At this time, the first spring 10 will rebound and push the clamping column 13 to slide on the inner wall of the circular groove 11 and slide to the clamping groove opened on the outer wall of the second connecting block 6. 28, at this time, the second connecting block 6 will no longer rotate on the inner wall of the main diagonal brace 5, and then the second fixing plate 7 will not rotate. At this time, the second fixing plate 7 can be fixed to the upper surface of the cross steel 9 by the second threaded column 8, thereby completing the installation of the entire connecting piece, which can effectively prevent the main diagonal brace 5 from angular deviation during installation, reduce installation time, and improve installation efficiency. The connecting piece can not only effectively prevent the main diagonal brace 5 from angular deviation during installation, reduce installation time, and improve installation efficiency, but also improve the convenience of installation and reduce time and cost at the construction site.
