Two second reinforcing beams 203 are symmetrically installed on the bottom outer side of the first vertical frame 201. The second reinforcing beams 203 are used to connect the first vertical frame 201 and the platform base 1, thereby also forming a stable triangular structure, thereby further improving the stability of the first bracket 2.

[0050] In this embodiment, the second bracket 3 includes a second vertical frame 301 and a horizontal frame 305. The second vertical frame 301 and the horizontal frame 305 are arranged vertically.
