At this time, after respectively clamping the first clamping block 111 and the second clamping block 133 on the cross bar and the vertical bar, fix them through the cooperation of the bolts and the positioning holes. Finally, rotate the first circular plate 131 to drive the first threaded rod 130 to rotate for fine adjustment to abut and support and fix the cross bar and the vertical bar.
