[0030] Beneficial effects:

[0031] When the steel structure is hinged, first loosen the bolt 10 and turn the knob 4. The knob 4 drives the forward and reverse screws 3 to rotate. The forward and reverse screws 3 drive the two movable seats 5 to move. The two movable seats 5 move to the two ends of the base 1, select the corresponding connecting piece 8, and pass the fixed shaft 7 at one end of the connecting piece 8 through the bearing 6 of one of the movable seats 5. Turn the knob 4 in the opposite direction, and the two movable seats 5 approach each other, so that the other fixed shaft 7 passes through the bearing 6 of the other movable seat 5, thereby effectively installing the connecting piece 8.
