Coil spring 5 and the cable of electric winch 3 provide additional limiting action for the steel frame through hooks 6. When the steel frame tends to swing under the action of wind force or external force, coil spring 5 and the cable of electric winch 3 will generate a reaction force to inhibit the swing of the steel frame. By hanging four hooks on four corners of the steel frame and cooperating with the cable of crane, the steel frame is fixed, which effectively prevents the steel frame from moving randomly during hoisting, especially during high-altitude installation or adjustment, which can inhibit the swing of the steel frame under the action of wind force or external force, so that the steel frame is more likely to be stationary, improves the stability of the hoisting process, and facilitates subsequent splicing or other operations, reduces the adjustment time caused by the swing of the steel frame, and significantly improves the installation efficiency of the stage steel frame.
