[0026] A mounting frame 13 is installed on the top of the mounting seat 8, and lifting support legs 14 are installed at the four corners of the bottom of the mounting frame 13. Limiting grooves 1301 are symmetrically provided at both ends of the inner side of the top of the mounting frame 13. A stage panel 15 is embedded in the top of the mounting frame 13. Fixing holes 1501 are symmetrically provided on the two outer sides of the stage panel 15. Limiting blocks 16 are symmetrically installed on the other two outer sides of the stage panel 15. Movable plates 17 are symmetrically embedded on the two outer sides of the mounting frame 13. Cavities 1302 are symmetrically provided at both ends of the interior of the mounting frame 13. Movable rods 18 are installed on the inner side walls of the cavity 1302. A reset spring 19 is installed on the outer ring surface of the movable rod 18, and a limiting plate 20 is installed on one end of the reset spring 19.

[0028] Furthermore, the outer ring surface of the support rod 12 is slidably connected to the inner wall of the sleeve 11, and a limit ring is provided on the top of the support rod 12 to prevent the sleeve 11 from separating from the support rod 12, thereby ensuring that the support frame 7 is lifted and lowered with increased stability through the support rod 12.

In the process of lifting and lowering, the lifting support legs 14 synchronously support the mounting frame 13, which increases the stability of the mounting frame 13, and the movable plate 17 is driven to be lifted and lowered by pulling the movable plate 17 outward. The movable rod 18 moves outward, and the movable rod 18 moves outward while driving the limit plate 20 to move and compressing the reset spring 19. One end of the movable rod 18 is retracted to the inside of the mounting frame 13, and the stage board 15 is embedded and installed on the top of the mounting frame 13 by connecting the limit block 16 to the limit groove 1301, and then the stage board 15 is embedded and installed on the top of the mounting frame 13 and the movable plate 17 is released.
