[0038] Working principle:

[0039] The first step is that when the equipment is used, the equipment needs to be installed at the designated position, when the equipment is installed on the assembly frame, the equipment needs to be lifted to reach the designated height, the slot below the mounting seat 41 is aligned with the cross bar on the assembly frame, the cross bar on the assembly frame is clamped on the lower surface of the mounting seat 41 and located on both sides of the U-shaped buckle plate 47, after clamping is completed, the rotating head 52 is twisted to drive the screw rod 51 to rotate on the U-shaped buckle plate 47, the screw rod 51 is provided with threads opposite to the threads, so that the two rectangular sliding blocks 49 move in opposite directions on the screw rod 51, the movement of the rectangular sliding blocks 49 drives the movement of the pressing plate 48, the pressing plate 48 is attached to the cross bar on the assembly frame, the attachment of the pressing plate 48 and the cross bar applies pressure to the side wall of the cross bar, achieving the installation of the equipment, the movement of the pressing plate 48 in the U-shaped buckle plate 47 is controlled to attach the pressing plate 48 to the cross bar on the assembly frame, generating extrusion pressure, and stably fixing the equipment on the assembly frame.
