[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 Four nuts 4 are provided, and the four nuts 4 are evenly distributed on the steel structure building board body 2.

Through the setting of the card slots 8, it is convenient to cooperate with the elastic clamping block 9 for clamping.

[0026] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5, a limiting mechanism 10 is jointly provided on the bolt 5 and the mounting bracket 1. The limiting mechanism 10 includes a limiting hole 101. The limiting hole 101 is provided on the surface of the bolt 5. There are multiple limiting holes 101, and the multiple limiting holes 101 are arranged in a circular array on the limiting rod 102.

The horizontal part of the mounting bracket 1 is slidably connected with a limiting rod 102, and the limiting rod 102 is slidably connected with the limiting hole 101. A moving piece 103 is fixedly sleeved on the outer side of the limiting rod 102, and the moving piece 103 is slidably connected with the horizontal part of the mounting bracket 1.
