[0010] As a further description of the above technical solution:

[0011] The upper side surface of the arc plate is arranged flush with the upper side surfaces of the movable mounting seat and the fixed mounting seat.

[0012] As a further description of the above technical solution:

[0013] An arc buckle is arranged at the end of the hook plate, and the arc buckle is hooked on the limit column.

[0014] As a further description of the above technical solution:

[0015] The limiting column, the fixing plate and the hook plate are arranged at the same height.

[0016] Compared with the prior art, the utility model provides a wire crimping pliers with a convenient disassembly and assembly of the cutter head, which has the following beneficial effects:

[0017] 1. In the utility model, a detachable crimping cutter head is designed, the crimping cutter head is arranged in a fitting and clamping manner, and a torsion spring is used to generate pressure, so that the limit column and the hook plate are hooked to fix the crimping cutter head;

[0018] 2. In the utility model, the replacement of the crimping cutter head is achieved by pulling the hook plate to disengage the limit column. The replacement speed is fast and the operation is extremely simple. The design fully utilizes the characteristics of the hydraulic crimping pliers telescopic rod to push the crimping and does not require the crimping cutter head to be installed particularly firmly.
