Detailed Implementation

[0037] like Figures 1-6 As shown, this application provides a telescopic adjustment plate 1, which includes a main body 10, a telescopic plate 20, a drive assembly 30, and a protective assembly 40.

[0038] Specifically, the main body 10 is composed of a support frame 11 and a main board 12.

The power structure 32 drives the telescopic plate 20 to extend and slide along the guide direction of the guide structure 31. Optionally, the guide direction of the guide structure 31 in this embodiment can be the length direction of the main board 12. When the telescopic plate 20 is retracted to its lowest point, the telescopic plate can be completely stored between the main board 12 and the support frame 11.

[0043] Optionally, in this embodiment, there are two baffles 13, which are respectively disposed on both sides of the main board 12 along the width direction.

The gasket 43 is disposed between the first support plate 412 and the second support plate 422 for fixing the first support plate 412 and the second support plate 422.

[0046] In this embodiment, the first protective plate 41, the second protective plate 42 and the gasket 43 are configured to limit the movement of the first guide wheel 311 and the second guide wheel 312 in the up-down and left-right directions.

[0047] Furthermore, the protective component 40 further includes a fixing tube 44, which is fixedly disposed on the side of the telescopic plate 20 near the support frame 11. The second protective plate 42 is further provided with an extension plate 423 parallel to the second support plate 422.
