A clamping structure is installed in the mounting hole of the fastening plate.

[0007] The utility model is further provided with the clamping structure, which comprises a clamping screw, a clamping nut and a clamping arc plate. The clamping screw is movably inserted into the mounting hole of the fastening plate. The clamping arc plate is installed at the inner side of one end of the clamping screw. The clamping nut is movably sleeved outside the clamping screw through threads.

[0008] The utility model is further provided with two limiting washers between the two size limiting nuts and the fastening plate. The two limiting washers are movably sleeved at both ends of the fixed U-shaped ring.

[0009] The utility model further sets up the central part of fastening plate is equipped with the radian of outward bulge.

[0010] The utility model further sets up the outside movable sleeve of clamping screw is equipped with the leveling washer, and the leveling washer is located between fastening plate and clamping nut.

[0011] The utility model further sets up the inner wall of clamping arc plate is equipped with a plurality of clamping nails.

[0012] The utility model has the advantages that: the utility model adjusts the size of the closed loop of the rigging clamp by screw thread, the screw thread has certain self-locking property, and the fastening property is better, and the rigging will not be loosened, meanwhile, only one nut needs to be twisted in the process of clamping, so that the clamping force is evenly distributed in the rigging clamp.
