[0023] The effect achieved by the entire embodiment 1 is that, by setting the positioning block 202, the positioning block 202 can be embedded in the positioning groove on the other sliding frame 201, and the clamping block 204 is clamped in the positioning hole 207 by the elastic force of the spring 205. At this time, the two sliding frames 201 can be fixed. When the sliding frame 201 with the convex threaded block 3 moves, the sliding frame 201 with the convex sliding block 12 can be driven to move, so that the installation area can be adjusted and the use effect of the device is improved.

[0024] Embodiment 2, as Figure 1-3 As shown, a mounting frame 4 is provided on the surface of the sliding frame 201, the sliding frame 201 is slidably connected to the base 1, the block 204 is slidably connected to the slide groove, and a limiting plate is provided on the lower surface of the slide rod 203, so that the block 204 is more stable when moving. A fixing plate 5 is provided on one side of the base 1, and a baffle 6 is installed on the other side of the base 1 by bolts. A threaded rod 7 is rotatably connected to the surface of the fixing plate 5 through a bearing, and the threaded rod 7 is threadedly connected to the convex threaded block 3, and the threaded rod 7 is slidably connected to the convex sliding block 12. A limiting rod 8 is provided on the surface of the fixing plate 5, and the convex threaded block 3 and the convex sliding block 12 are both slidably connected to the limiting rod 8. A plurality of supporting tubes 9 are rotatably connected to the surface of the baffle 6 through a bearing, and the threaded rod 7 and the limiting rod 8 both pass through the supporting tube 9. A forward and reverse motor 11 is installed on the surface of the fixing plate 5, and the output end of the forward and reverse motor 11 is fixedly connected to the threaded rod 7.

[0025] The effect achieved by the entire embodiment 2 is that the provided mounting frame 4 is convenient for subsequent installation with an object, the provided limit plate can prevent the sliding rod 203 from sliding out of the limit groove, the provided threaded rod 7 can drive the convex threaded block 3 to move, and the threaded rod 7 is slidably connected with the convex sliding block 12, which makes it easy to install the convex sliding block 12. When adding a sliding frame 201, there is no need to move the position of the previous sliding frame 201. The provided limit rod 8 can make the convex threaded block 3 and the convex sliding block 12 more stable when moving, and can reduce the pressure on the threaded rod 7.
