Power tool with deployable appendage

1 . A power tool comprising:

an outer casing forming a housing;

a motor;

a motor-driven appendage having a distal end, a proximal end, a secured portion, and an unsecured portion, the secured portion positioned near the proximal end, anchoring the motor-driven appendage within the housing, and the unsecured portion consisting of a portion of the motor-driven appendage distal to the secured portion;

a hinge mechanism having a hinge axis between an appendage-leg and a motor-leg, the appendage-leg comprising the motor-driven appendage and the motor-leg comprising an output shaft affixed to the motor;

wherein the motor-driven appendage has a closed state and an open state, the closed state defined by the unsecured portion fully contained within the housing, and the open state defined by the unsecured portion being in the space external to the outer casing,

wherein the hinge axis is a lock-pin shaft,

wherein the lock-pin shaft engages to render the motor-driven appendage in a locked position to restrict the motor-driven appendage from hinging about the hinge axis and disengages to render the motor-driven appendage in an unlocked position to enable the motor-driven appendage to hinge about the hinge axis.

2 . The power tool of claim 1 , wherein:

the housing comprises an appendage port adjacent to the secured portion and capable of housing the unsecured portion;

the outer casing comprises an aperture creating consecutive space between the appendage port and a space external to the outer casing, the aperture shaped to allow the unsecured portion to pass through it, laterally and longitudinally; and

the motor-driven appendage moves between the closed state and the open state by hinging about the hinge axis and by laterally passing through the aperture.

3 . The power tool of claim 1 , wherein a battery powers the motor.

4 . The power tool of claim 1 , wherein a microprocessor couples the motor to a battery configured to power the motor.

5 . The power tool of claim 1 , wherein an angled hinge-blade maintains the motor-driven appendage perpendicularly to the lock-pin shaft.

6 . The power tool of claim 1 , wherein the motor-leg comprises a proximal pinion gear affixed to the output shaft; and wherein the proximal pinion gear articulates with a bevel gear through a plurality of gears.

7 . The power tool of claim 1 , wherein:

the appendage-leg comprises the proximal end of the motor-driven appendage connected to a distal pinion gear;

the distal pinion gear articulating with a bevel gear, either directly, or indirectly, through a plurality of gears; and

the motor-driven appendage hinges about the hinge axis using the distal pinion gear's articulation with the bevel gear through the plurality of gears.

8 . The power tool of claim 1 , wherein the outer casing is compact such that it fits within one's pocket and within a palm of one's hand.

9 . A power tool comprising:

an outer casing forming a housing;

a motor;

a motor-driven appendage having a distal end and a proximal end;

the proximal end of the motor-driven appendage connected to a distal pinion gear, the distal pinion gear articulating with a bevel gear through a plurality of gears;

the bevel gear affixed to a lock-pin shaft, the lock-pin shaft extending perpendicularly from the bevel gear, in axial alignment;

the bevel gear further articulating with a proximal pinion gear, either directly or indirectly, through a plurality of gears;

the proximal pinion gear affixed to an output shaft; the output shaft affixed to a motor; and

the lock-pin shaft acting as a hinge axis about which the motor-driven appendage hinges; the lock-pin shaft engaging to restrict the motor-driven appendage from hinging about the hinge axis in a locked position and disengaging to enable the motor-driven appendage to hinge about the hinge axis in an unlocked position.

10 . The power tool of claim 9 , wherein, in the locked position, but not the unlocked position, rotation of the proximal pinion gear translates to rotation of the motor-driven appendage through the proximal pinion gear's articulation with the bevel gear, either directly or indirectly, through the plurality of gears, and through the bevel gear's articulation with the distal pinion gear, either directly or indirectly, through the plurality of gears.

11 . The power tool of claim 9 , wherein an angled hinge-blade holds the proximal end of the motor-driven appendage perpendicularly to the lock-pin shaft.

12 . The power tool of claim 9 , wherein the outer casing is compact such that it fits within one's pocket and within a palm of one's hand.

13 . The power tool of claim 9 , wherein a microprocessor couples the motor to a battery configured to power the motor.

14 . The power tool of claim 13 , wherein the power tool has a first directional button and a second directional button, wherein:

the first directional button is coupled to the battery, the motor, and the microprocessor such that pressing the first directional button causes rotational movement of the motor-driven appendage in a clockwise direction, and

the second directional button is coupled to the battery, the motor, and the microprocessor such that pressing the second directional button causes rotational movement of the motor-driven appendage in a counter-clockwise direction.

15 . The power tool of claim 13 , wherein the power tool has a speed switch that communicates with the battery, the motor, and the microprocessor such that when mechanically manipulated, the speed switch varies a speed at which the motor-driven appendage rotates.
