[0043] In the embodiment, a guide rod 13 is further arranged on the support 11.

[0044] With the structure, the guide rod 13 plays a role in guiding the butt joint of the secondary beams.

[0045] In the embodiment, the upper end of the inclined rod 12 is provided with a protrusion 14, the protrusion 14 is sleeved with a ring block 15, and the ring block 15 is fixed with a Z-shaped handle 16.
