[0056] When the vertical rod 11 slides upward, the lower locking mechanism 16 is sleeved on the outside of the upper pre-tightening mechanism 13 to lock the crossbar assembly 2 and the transverse support rod 3;

[0057] When the construction personnel apply a thrust in the direction of the vertical pole 11 through the hinge arm 168, the first linkage ring 164 is driven to move up along the direction of the vertical pole 11, the internal threaded cylinder 161 is sleeved on the outside of the pre-tightening cylinder 131, and the internal threaded cylinder 161 is rotated to be threadedly connected to the outside of the external threaded teeth 134, so as to lock the pre-tightening cylinder 131;

[0058] By utilizing the locking area 23 set on the cross bar 21, when the cross bar 21 passes through the first through hole 14, the locking area 23 can be synchronously extended into the first through hole 14. When the construction personnel use tools to rotate the polygonal ring 163, the internal threaded tube 161 can be driven to continuously move upward so that the edge of the port is clamped in the embedded groove 22, which is used to further reinforce the cross bar 21 in the first through hole 14.
