Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
All other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-3, the utility model provides a kind of technical solution: a kind of business management politics of the firm teaching is pacified with projector
Platform is filled, including bracket 1 and supporting plate 6,1 appearance wall of bracket are rotatably connected to the first drive rod 2, and the first drive rod 2 by shaft
Inside offers first sliding groove 5, and 5 internal slide of first sliding groove is connected with sliding axle 4, and the first drive rod 2 passes through sliding axle 4 and the
The rotation connection of two drive rods 12, first sliding groove 5 offer tooth socket 8 far from the side of bracket 1, and engagement is connected with inside tooth socket 8
Motion thread column 9,1 bottom of bracket are fitted with supporting plate 6, and the annular that supporting plate 6 is welded by opening up annular groove 7 with 1 bottom of bracket
Fixture block 10 is clamped, and 7 inside top table wall central axis of annular groove is welded with convex block 16, and convex block 16 pushes up table wall and passes through the second compression bullet
Spring 17 and 19 elastic connection of pressing plate offer second sliding slot 14, and 14 side table wall of second sliding slot inside 19 two sides annular groove 7 of pressing plate
It is rotatably connected to sliding block 18 by shaft, so that can rotate at the top of sliding block 18 and block projector.
