In order to avoid that the left supporting plate 61 and the right supporting plate 62 bear larger gravity and are bent sideways, the requirement of supporting force is not met, and supporting force is ensured through the transverse supporting channel steel 5.

In order to facilitate the connection strength of the transverse strut channel steel 5 with the left support plate 61 and the right support plate 62. The two lateral sides of the two ends of the transverse supporting channel steel 5 are folded to form folded plates 51, the center of each folded plate 51 is provided with an assembly hole 52, the positions adapting to the assembly holes 52 penetrate through the left supporting plate 61 and the right supporting plate 62 to form matching holes 63 respectively, and the penetrating assembly holes 52 are fixedly connected with the matching holes 63 through fixing pieces.
