When the adjusting plate 3 drives the supporting plate 4 to move up and down, the lifting seat 6 moves up and down in the groove 11 along the guide slide bar 12, which has a guiding and limiting function so that the supporting plate 4 can maintain a horizontal state.

[0021] Further, a slide groove is provided on the lifting seat 6, and the side wall of the support plate 4 is slidably connected with the slide groove of the lifting seat 6.
