The pliers head 1 can be detachably installed in the interface. The pliers head 1 includes an inner caliper head 11 and an outer caliper head 12. The head can be chrome vanadium steel head, and can have other different configurations according to different needs. The main rod 2 of the pliers body and the auxiliary rod 3 of the pliers body are respectively provided with connecting ears 41, and the two connecting ears 41 are hinged through the connecting shaft 4. The tail is provided with a connecting rod square tenon 91 . The square tenon 91 and the square hole 92 are matched, and can be combined with each other, and can be inserted and fixed. The multi-purpose booster rod 5 has two connecting rod square holes 92 , one square hole is arranged on the head, and one square hole is arranged on the side, namely the connection port 51 . The multi-purpose booster rod 5 is detachably installed on the connecting rod square tenon 91 at the tail of the secondary rod 3 of the caliper body through the square hole 92 in the head. The socket wrench joint 6 is used to connect the socket pliers head, and square tenons 91 are provided at both ends of the socket wrench. In the combined state, it is connected to the square hole 92 at the tail of the main rod 2 of the pliers body. When the split state is shown in Figure 3, both It can be detachably connected to the connection port 51 , and can also be detachably connected to the square hole 92 of the head of the multi-purpose booster rod 5 .
