[0047] Moreover, the two plate structures are symmetrical and parallel to the axis of the corresponding round tube, so that the axial force of the diagonal brace 14 can be applied to the diagonal brace 14 after the diagonal brace 14 is connected to the clamping ear plate 22, which is more reliable, easier to control the assembly quality, and ensure the overall safety of the structure.

[0048] In some embodiments, each clamping piece 21 is formed by opening a through groove 24 passing through the axis in the tube wall near the end of the corresponding circular tube, and then pressing the tube wall into two parallel plate structures.
