[0028] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Please refer to the attached Figure 1-4 A replaceable pliers set structure includes a pliers rod 1 and a pliers handle 2. The pliers handle 2 includes a fixed handle 3 and a movable handle 4 movably connected to the fixed handle 3. The end of the fixed handle 3 is provided with a connecting port 5. One end of the pliers rod 1 is inserted into the connecting port 5 for use. The pliers rod 1 can be disassembled and replaced for use as needed, which is also convenient for subsequent cleaning and maintenance.

[0030] When used specifically:

[0031] A transmission assembly is provided in the fixed handle 3 and connected to the movable handle 4. A fixed head 6 and a hinged movable head 7 are provided at the end of the pliers rod 1 away from the pliers handle 2. A linkage rod 8 connected to the end of the movable head 7 is movably connected in the pliers rod 1. The linkage rod 8 is arranged in linkage with the transmission assembly. The linkage rod 8 is driven by the transmission assembly to complete the movement of the movable head 7 and the use of the pliers head is completed.

[0032] In one embodiment

[0033] Transmission assembly: The fixed handle 3 is provided with two sets of upper and lower shaft bodies, the end of the movable handle 4 is sleeved with the lower shaft body, and a driven ratchet 16 is sleeved on the upper shaft body. The end of the movable handle 4 is provided with a driving tooth 17 that is meshed with the driven ratchet 16. A push rod 18 is hinged on one end of the driven ratchet 16 toward the connecting port 5, and the linkage rod 8 is sleeved in the push rod 18. The movement of the push rod 18 controls the movement of the linkage rod 8 to complete the transmission control.

[0034] In one embodiment:

[0035] A rotating sleeve 9 is sleeved on one end of the clamp rod 1 near the connecting port 5, and a vertically arranged sliding groove 10 is recessed in the end of the fixed handle 3 near the connecting port 5. A positioning sleeve 11 is slidably sleeved in the sliding groove 10. The positioning sleeve 11 is sleeved and fixed to the end of the clamp rod 1, and the assembly and use of the clamp rod 1 is completed through the positioning sleeve 11.

[0036] More specifically, the upper and lower ends of the positioning sleeve 11 are respectively recessed with a slide groove opening 12 and a limit opening 13, the slide groove 10 is connected to a limit rod 14 that is inserted into the slide groove opening 12, the limit opening 13 is arranged toward the direction of the clamp rod 1, and the outer wall of the rotating sleeve 10 is recessed with two groups of symmetrically arranged limit grooves 15 in cooperation with the limit opening 13. The setting of the two groups of limit grooves 15 allows the clamp rod 1 to have two specific installation directions, so that the direction of the clamp head can be changed for use to meet different needs. The targeted setting of the rotating sleeve 9 facilitates the memory of the rotation angle. During disassembly and assembly, the positioning sleeve 11 needs to be pressed to release the lock on the limit groove 15, and the disassembly can be completed by rotating the rotating sleeve 9 90° and pulling it out.

[0037] In one embodiment

[0038] In order to ensure the stability of the stroke during use, the end of the push rod 18 is inserted into the rotating sleeve 9, and a protrusion 19 is provided on the push rod 18 near the driven ratchet 16. A groove 20 is provided on the driven ratchet 16 to cooperate with the protrusion 19. At the same time, a stroke limit block 21 is also connected to the movable handle 4 along its movement direction for use.

[0039] The active teeth are driven to mesh with the driven ratchet wheel by pinching the movable handle, so as to adjust the position of the push rod 18 and complete the linkage control of the linkage rod. The end of the linkage rod is hinged with the movable head to drive it to move and complete the use of the pliers head.
