The support is detachably arranged on the connecting rod. The support is provided with two U-shaped grooves in the same direction. The steel bar truss includes two bottom trusses, and the two bottom trusses are respectively clamped in the two U-shaped grooves.

[0005] Further, a plurality of slots are arranged at intervals along the length direction of the connecting rod, and the middle part of the support is inserted into the slots.
