The second base 12 includes a second body 121, two second extensions 122 and a second connecting seat 123. The second base 12 has the same structure as the first base 11, and will not be described in detail here. The first connecting seat 113 and the second connecting seat 123 are connected by a stabilizing member, thereby connecting the first base 11 and the second base 12. In this embodiment, the stabilizing member can be a bolt.

[0041] like Figure 1 and Figure 2 As shown. The column 2 is arranged vertically perpendicular to the base 1. Specifically, two columns are arranged symmetrically. One of them is perpendicular to the first base 11, and the other is perpendicular to the second base 12. Each column 2 includes a column body 21, a connecting plate 22, a baffle 23 and a reinforcing beam 24.

[0042] The column body 21 is configured as a box-type structure composed of two plate-frame structures and welded beam members. Each plate-frame structure includes a groove 211 and a pad 212; the opening of each groove 211 is outward, and the two grooves 211 are symmetrically arranged, forming a accommodating space in the middle, and the pad 212 is fixedly connected to the groove body of the groove 211. The outer side surfaces of the two grooves 211 close to the end of the base 1 are connected from top to bottom by multiple connecting plates 22. The outer side surfaces of the two grooves 211 away from the end of the base 1 are connected from top to bottom by multiple baffles 23. The multiple connecting plates 22 and the multiple baffles 23 are staggered. A plurality of reinforcing beams 24 are obliquely arranged near the bottom of the column body 21, one end of which is connected to the side of the column body 21, and the other end is connected to the base 1.
