[0035] In the present technical solution, the adjustment mechanism includes a movable shaft 18 and a threaded shaft 19. The bottom of the movable shaft 18 is fixedly connected to a limiting rod 21. The top edge of the threaded shaft 19 is provided with a groove 20 that engages with the limiting rod 21, and the top of the movable shaft 18 is connected to the support rod 3 through a second connecting rod 22.

[0036] In the present technical solution, there are four support blocks 4 , each of which is an L-shaped structure and overlaps with the plate 12 on all sides, and the plate 12 is inserted through the surface of the guide rod 5 .

[0037] In this technical solution, the limiting mechanism includes a movable rod 14 and a clamping rod 16. The movable rod 14 is embedded and plugged into the top of the column 1. The bottom of the movable rod 14 is connected to the inside of the column 1 through a spring 15, and the top of the movable rod 14 is rotatably connected to the clamping rod 16.

[0038] In this technical solution, the clamping rod 16 is a T-shaped structure with clamping blocks 17 fixedly connected at both ends. The top of the clamping rod 16 is located between two symmetrically distributed limiting plates 13 . The cross-section of the limiting plate 13 is an L-shaped structure and is engaged with the clamping block 17 .

[0039] In the present technical solution, there are four limiting rods 21 , each limiting rod 21 has an L-shaped cross section, and the bottom of the limiting rod 21 is slidably connected to the inside of the groove 20 .
