[0023] Specifically, Figure 1 and Figure 3 As shown, when in use, after the fixing bolt 8 is loosened, the expansion plate 6 inside the storage slot 5 can slide outward, so that the position of the side end platform 9 can be moved and adjusted. After the adjustment is completed, the fixing bolt 8 can be tightened to fix it;
[0024] The surface of the object platform 9 is provided with a mounting hole 10, and an insertion rod 11 is provided inside the mounting hole 10. The cross section of the insertion rod 11 is smaller than the cross section of the mounting hole 10. The insertion rod 11 and the mounting hole 10 form a detachable structure. A mounting nut 12 is provided on the outside of the insertion rod 11, and a hanging hook 13 is fixed to the bottom end of the insertion rod 11.
[0025] Specifically, Figure 1 and Figure 3As shown, when in use, the insertion rod 11 at the top of the hanging hook 13 can be inserted into the mounting hole 10 on the surface of the platform 9, and then the outer mounting nut 12 is rotated to install the hanging hook 13 at the bottom position of the platform 9 for use;
[0026] A rod assembly is provided at the bottom end of the balance board 2, and the rod assembly includes a guide rod 16, a guide platform 18 and a spring 19. A slide groove 14 is provided at the bottom end of the balance board 2. Four groups of slide grooves 14 are provided at the bottom end of the balance board 2, and the four groups of slide grooves 14 are symmetrically distributed. A sliding ball 15 is provided inside the slide groove 14. The cross section of the sliding ball 15 is smaller than the cross section of the slide groove 14.
