said mounting blocks on each side of said threaded rod and polygonal sleeve tube, each having one or more pointed stakes/spikes capable of affixing said fan/fixture box and adjustable brace to each respective stud within the ceiling when said threaded rod is threadably moved toward said studs to form a tight fit there between;

said fan/fixture box being mounted and installed in a horizontal level orientation parallel to the preexisting drywall or ceiling panel, while said fan/fixture box extends downward to hold heavy components of a ceiling fan and associated lighting;

said mounting blocks each having a round plate extending in which a distal end of said threaded rod is engaged, within a tubular reciprocal threaded sleeve of said round plate, mating with respective threads of said threaded rod, on one inner-facing side of said mounting block; and

said round plate further having a larger diameter round distal plate, on the other outer-stud-facing side of said mounting block, said larger diameter round distal plate having said protruding stakes/spikes engageable with a respective stud above the preexisting drywall or ceiling panel to fix said adjustable brace with said threaded rod securely and horizontally level in place, where said fan/fixture box descends directly vertically down through the round hole in the preexisting drywall or ceiling panel, wherein the fan/fixture box is oriented in a vertical position below said threaded rod.

2 . The stable fan/fixture box and adjustable brace for ceiling fan electrical boxes in old work environments as in claim 1 further comprising said rectangular opposite end mounting blocks being configured with four sides, where the normally bottom edge has a predetermined fixed distance from a midpoint of a hole for said level threaded rod, which said predetermined fixed distance is equal to the distance from the left and right-side edges, also in an equal distance from the hole for a level threaded rod, so that if one end mounting block topples over on its side edge, the threaded rod will remain level and horizontal above the backside of the preexisting drywall or ceiling panel.

3 . The stable fan/fixture box and adjustable brace for ceiling fan electrical boxes in old work environments as in claim 2 further comprising at respective opposite ends of said mounting blocks there are provided respective left and right end plates with pointed stakes/spikes engageable with respective smooth sides of the studs on either side of the hole in the preexisting drywall or ceiling panel.

4 . The stable fan/fixture box and adjustable brace for ceiling fan electrical boxes in old work environments as in claim 2 wherein said adjustable brace is advanced toward said respective mounting end mounting blocks, as the installer turns said threaded rod within said polygonal sleeve tube so that said pointed stakes/spikes on either side of said mounting blocks point into the studs on either side of said mounting blocks.

5 . The stable fan/fixture box as in claim 1 wherein solid insert having a threaded hole therewithin, frictionally fit within an outer polygonal sleeve tube, wherein said frictionally fit solid insert is at least about four inches in length to support said threaded rod within said outer sleeve of said adjustable brace.

6 . The stable fan/fixture box and adjustable brace for ceiling fan electrical boxes in old work environments as in claim 1 wherein said polygonal sleeve tube is hexagonal in shape and said “friction fit” insert is hexagonal in shape.

7 . The stable fan/fixture box and adjustable brace for ceiling fan electrical boxes in old work environments as in claim 1 wherein said polygonal sleeve tube is attached to said fan/fixture box by a saddle brace having a top and inner side surfaces which conform in shape to the respective top and outer side polygonal surfaces of said polygonal sleeve tube, said saddle brace having opposite horizontal flanges having holes for insertion of said screw fasteners through each said flange and then into said fan/fixture box, said fan/fixture box being fastened in place securely to said saddle brace and therefore also to said polygonal tube sleeve having said threaded rod threadably in place therein.

8 . The stable fan/fixture box and adjustable brace for ceiling fan electrical boxes in old work environments as in claim 1 further comprising said polygonal tube sleeve being insertable within the hole in the preexisting drywall or ceiling panel and configured to be grasped by the installer and rotated manually to advance said threaded rod and said distal end mounting block toward a distal stud, wherein when said proximal end mounting block is in contact with a proximal, opposite facing stud.

9 . The stable fan/fixture box and adjustable brace for ceiling fan electrical boxes in old work environments as in claim 1 further comprising said fan/fixture box and adjustable brace supports a ceiling fan horizontally level below the preexisting drywall or ceiling panel with said mounting box for the ceiling fan and lighting components extending downward in a vertical orientation below a backside of said preexisting drywall or ceiling panel.

10 . The stable fan/fixture box and adjustable brace as in claim 1 , further comprising visual indicia indicating the direction of turning said polygonal sleeve tube.

11 . The stable fan/fixture box and adjustable brace for ceiling fan electrical boxes in old work environments as in claim 1 , further comprising: a crisscrossed recess in an end of said round plate, said crisscrossed recess configured to receive a bit of a drill before said threaded rod is inserted into the ceiling, wherein said mounting blocks are thereby configured to be moved by using the drill and bit to cause rotational movement of said threaded rod.

12 . The stable fan/fixture box and adjustable brace as in claim 1 , wherein said threaded rod has visual indicia indicating the limits of moving said threaded rod within said insert.

13 . A stable fan/fixture box and adjustable brace for ceiling fan electrical boxes in old work environments where a said fan/fixture box must be mounted and stabilized above the backside of the ceiling between a pair of adjacent ceiling studs, and where only a small hole can be made in the preexisting drywall or ceiling panel in order for an installer to carry and insert the fan/fixture box and adjustable brace into the small hole, without any visual access to the area above the preexisting drywall or ceiling panel, comprising:

said fan/fixture box supported by an adjustable brace wherein said fan/fixture box is mounted and extends through a hole in a vertical downward direction;

said fan/fixture box and adjustable brace having a threaded rod, said threaded rod being expandable by turning, so that said threaded rod moves between the adjacent ceiling studs above the preexisting drywall or ceiling panel;

said threaded rod being supported within a solid insert having a threaded hole therewithin, said solid insert frictionally fit within an outer polygonal sleeve tube;

said threaded rod, said insert and said polygonal sleeve tube being supported by opposite mounting blocks;

said mounting blocks being rectangular and having perpendicular walls, wherein if one of said mounting blocks falls over on one side, said fan/fixture box and adjustable brace will still remain level and horizontal when moved by the installer's hand reaching up into the dark hole above the preexisting drywall or ceiling panel;

said mounting blocks on each side of said threaded rod and polygonal sleeve tube, each having one or more pointed stakes/spikes capable of affixing said fan/fixture box and adjustable brace to each of the respective ceiling studs when said threaded rod is threadably rotated to form a tight fit there between;

said fan/fixture box being mounted and installed in a horizontal level orientation parallel to the preexisting drywall or ceiling panel, while said fan/fixture box extends downward to hold heavy components of a ceiling fan and associated lighting;

said mounting blocks each having a round plate extending in which a distal end of said threaded rod is engaged, within a tubular reciprocal threaded sleeve of said round plate, mating with respective threads of said threaded rod, on one inner-facing side of said mounting block; and

said round plate further having a larger diameter round distal plate, on the other outer-stud-facing side of said mounting block, said larger diameter round distal plate having said protruding stakes/spikes engageable with a respective one of the adjacent ceiling studs to fix said adjustable brace with said threaded rod securely and horizontally level in place, where said fan/fixture box descends directly vertically down through the round hole in the preexisting drywall or ceiling panel, wherein the fan/fixture box is oriented in a vertical position below said threaded rod.
