By utilizing the overall arrangement of the bolt head, a thickened reinforcement sleeve is arranged on one side of the bolt head, and a pressure head is arranged at the same time, so that during disassembly and installation, the staff can directly pinch the pressure head to prevent it from slipping as a whole. By arranging the main gasket and the auxiliary gasket, the device can fully squeeze and rub with the surface of the clamped object through the friction protrusions and the auxiliary gasket, and the friction force is relatively large, which effectively prevents slipping during installation.

[0019] (2) The easily disassembled high-strength bolt connection substructure is fixedly connected with an anti-sliding block through the surface of the nut. The shape of the anti-sliding block is arc-shaped. By setting the nut, the device can directly hold the anti-sliding block through the external anti-sliding block without slipping, which is convenient and quick to operate.
