Vacuum mount type support device

1. A vacuum mount type support device, comprising:

a vacuum mount base member, said vacuum mount base member comprising a multilateral upright shaft, and a rubber disk located on a bottom side of said multilateral upright shaft for attaching to a smooth surface for producing a vacuum suction force, said multilateral upright shaft having an outer thread extending around the periphery of a lower part thereof, and a connector located on a top end thereof; a first arm rotatably connected to said multilateral upright shaft, said first arm rotating about a first horizontal rotational axis formed by said connector of said multilateral upright shaft; a second arm rotatably connected to said first arm, said second arm rotating about a second horizontal rotational axis formed through connection of said second arm to said first arm; annular teeth rotatably connected to said second arm, said annular teeth rotating about a vertical axis formed through connection of said second arm to said annular teeth; a vacuum mount cap member made of a hard material, said vacuum mount cap member having a cup-like body capped on a top side of said rubber disk of said vacuum mount base member and a through hole cut through the center of said cup-like body for the passing of said multilateral upright shaft, said multilateral upright shaft extending both through and above said through hole to expose said connector located on the top end of said multilateral upright shaft; a control device sleeved onto said multilateral upright shaft and rotatably to impart a pressure to said vacuum mount cap member against said vacuum mount base member, said control device having an inner thread threaded onto the outer thread of said vacuum mount base member; a stop member fastened to said multilateral upright shaft to prohibit escape of said vacuum mount cap member from said multilateral upright shaft; and a device holder for holding an external device, a top of said annular teeth being connected to a bottom of said device holder.

2. The vacuum mount type support device as claimed in claim 1 , wherein said rubber disk has a flat polyurethane pad bonded to a bottom side thereof.

3. The vacuum mount type support device as claimed in claim 1 , wherein said device holder comprises a recessed holder base, a mounting portion located on a bottom side of said recessed holder base for mounting, an extension bar extended from one side of said recessed holder base, a shell fastened to said extension bar, and a clamping plate inserted into said shell and movable in and out of said shell between a received position and an extended position and biasable relative to said shell when extended out of said shell to the extended position.

4. A vacuum mount type support device, comprising: a vacuum mount base member, said vacuum mount base member comprising a multilateral upright shaft, and a rubber disk located on a bottom side of said multilateral upright shaft for attaching to a smooth surface for producing a vacuum suction force, said multilateral upright shaft having a connector located on a top end thereof; a first arm rotatably connected to said multilateral upright shaft, said first arm rotating about a first horizontal rotational axis formed by said connector of said multilateral upright shaft; a second arm rotatably connected to said first arm, said second arm rotating about a second horizontal rotational axis formed through connection of said second arm to said first arm; annular teeth rotatably connected to said second arm, said annular teeth rotating about a vertical axis formed through connection of said second arm to said annular teeth; a vacuum mount cap member made of a hard material, said vacuum mount cap member having a cup-like body capped on a top side of said rubber disk of said vacuum mount base member and a through hole cut through the center of said cup-like body for the passing of said multilateral upright shaft, said multilateral upright shaft extending both through and above said through hole to expose said connector located on the top end of said multilateral upright shaft; a control device pivotally connected to said vacuum mount cap member and biasable relative to said vacuum mount cap member to impart a pressure to said vacuum mount cap member against said vacuum mount base member, said control device having two cam portions kept in contact with a top surface of said vacuum mount cap member; a stop member fastened to said multilateral upright shaft to prohibit escape of said vacuum mount cap member from said multilateral upright shaft; and a device holder for holding an external device, a top of said annular teeth being connected to a bottom of said device holder.

5. The vacuum mount type support device as claimed in claim 4 , wherein said rubber disk has a flat polyurethane pad bonded to a bottom side thereof.

6. The vacuum mount type support device as claimed in claim 4 , wherein said device holder comprises a recessed holder base, a mounting portion located on a bottom side of said recessed holder base for mounting, an extension bar extended from one side of said recessed holder base, a shell fastened to said extension bar, and a clamping plate inserted into said shell and movable in and out of said shell between a received position and an extended position and biasable relative to said shell when extended out of said shell to the extended position.
