[0038] Figure 4 It is a schematic diagram of the three-dimensional structure of the mounting bracket in the first embodiment of the present invention.

[0039] like Figure 1 and Figure 4 As shown, the mounting bracket member 12 is a special-shaped profile structure with a bent cross section, and one end thereof has a fitting surface 12a that can fit with the side surface 11a of the beam member 11; the fitting surface 12a is provided with a positioning rib 121 that protrudes outward and matches the longitudinal guide groove 111. In the first embodiment, a 0.1 mm gap is reserved on one side of the longitudinal guide groove 111 and the positioning rib 121, which can ensure positioning accuracy and prevent the problem that the positioning rib 121 cannot be installed in the longitudinal guide groove 111 due to manufacturing errors.
