An adjustable support device includes a housing secured on a base, a platform pivotally secured to the housing for supporting a level facility. A threaded member is rotatably supported on the base, a motor is coupled to the threaded member to rotate the threaded member relative to the base. A follower is threaded to the threaded member and pivotally coupled to the platform with a link, to allow the platform to be rotated toward and away from the housing by the motor. A receiver device is received in the housing, and a remote control device may emit control signals to the receiver device, to control the motor to rotate the threaded member, and to rotate and to adjust the platform toward and away from the housing.

I claim: 1. An adjustable support device comprising: a base, a housing secured onto said base, a platform including a first end pivotally secured to said housing with a pivot shaft, to allow said platform to be rotated up and down relative to said housing to different angular positions, a level facility supported on said platform, a threaded member rotatably supported on said base and received in said housing, a motor disposed in said housing and coupled to said threaded member, to rotate said threaded member relative to said base and said housing, a follower threaded to said threaded member, a link pivotally coupled between said follower and said platform, to pivotally couple said platform to said follower, and to allow said platform to be rotated toward and away from said housing by said motor via said threaded member and said follower, a receiver device received in said housing, and a remote control device for emitting control signals to said receiver device, and to control said motor to rotate said threaded member, and to rotate and to adjust said platform and said level facility up and down relative to said housing to different angular positions. 2. The adjustable support device for level facility as claimed in claim 1, wherein said housing includes a casing secured therein to rotatably receive and support said threaded member. 3. The adjustable support device for level facility as claimed in claim 2, wherein said casing includes two end brackets secured thereto to rotatably receive and support said threaded member. 4. The adjustable support device for level facility as claimed in claim 3, wherein said motor is secured to one of said end brackets of said casing. 5. The adjustable support device for level facility as claimed in claim 1, wherein said housing includes a passage formed therein, said follower includes at least one flap extended therefrom, and extended out through said passage of said housing, and pivotally coupled to said link. 6. The adjustable support device for level facility as claimed in claim 5, wherein said casing includes a bar secured on top thereof and received in said passage of said housing, and having a width smaller than that of said passage of said housing, to form at least one slot between said bar and said housing, and to slidably receive said at least one flap of said follower. 7. The adjustable support device for level facility as claimed in claim 1, wherein said housing includes a cap disposed therein and located in front of said receiver device, to allow said receiver device to receive the control signals from said remote control device. 8. The adjustable support device for level facility as claimed in claim 1, wherein said motor includes a reduction gearing attached thereto, to reduce a rotational speed of a spindle of said motor. 9. The adjustable support device for level facility as claimed in claim 1 further comprising a seat disposed below said base, and a table rotatably attached onto said seat, and including at least one latch provided thereon, for engaging with said base, and for securing said base on said table, and to allow said base on said table to be rotated and adjusted relative to said seat. 10. The adjustable support device for level facility as claimed in claim 9, wherein said base includes a plurality of foot stands threaded thereto, to adjustably support said base above ground, and to selectively elevate and space said seat from the ground. 11. The adjustable support device for level facility as claimed in claim 1, wherein said base includes two switches disposed thereon and located close to two end portions of said threaded member, for being actuated by said follower, and to control and to limit a movement of said follower relative to said threaded member.
