The clamp is a connecting device for connecting pipe fittings, valves and pipe fittings with grooves. It is used to tighten the joints. Generally, clamps can be divided into worm drive type, bolt structure type clamps, etc. The clamps of the bolt structure all use bolts to connect and fasten the opening of the clamp. The structure is simple and the cost is low. It is widely used in occasions where disassembly is not frequent and requires high firmness. The bolt structure clamps in the prior art are mostly used.
