[0049] The plier head further comprises a one-way bearing 26 and a positioning sheet 27. The outer peripheral surface of the one-way bearing 26 cooperates with the plier head body, and the one-way bearing 26 is sleeved on the rotating shaft part 23 to limit the one-way rotation of the rotating shaft part, thereby limiting the one-way rotation of the winding wheel. The positioning sheet 27 is arranged in the positioning part 24. The positioning sheet 27 and the transmission part 22 jointly clamp the rotating shaft part 23 in the one-way bearing 26. The one-way bearing 26 and the plier head body are respectively provided with a groove 14 structure, and the one-way bearing 26 and the groove of the plier head body are positioned and fixed by a positioning pin shaft 15. In other embodiments, the positioning can also be achieved by the relative arrangement of the groove and the protrusion.

[0050] The second handle 4 is provided with a rotating hole 41, and the side wall of the rotating hole 41 is provided with an inner groove 42. The ratchet assembly 5 comprises a gear ring 51, a pawl 52 and a pawl reset member 53. The pawl 52 and the pawl reset member 53 are arranged in the inner groove 42. One end of the pawl reset member 53 abuts against the bottom wall of the inner groove 42. The bottom wall of the inner groove 42 can be further provided with a containing hole for containing the pawl reset member to limit the movement of the pawl reset member. The shape of the inner groove can be a circular arc groove. The other end of the pawl reset member 53 is connected with the pawl 52. The outer periphery of the gear ring 51 is provided with external teeth. The gear ring 51 is arranged in the rotating hole 41, and the pawl 52 is connected with the external teeth of the gear ring 51. The transmission part 22 is connected with the gear ring 51.

[0051] The wire tightening pliers further comprise a reset tension spring 7. One end of the reset tension spring is connected with the second handle 4, and the other end of the reset tension spring is connected with the plier head body.

[0052] Please refer to Figure 13 and Figure 14 . In use, one end of the cable is clamped on the locking assembly, the other end of the cable is clamped in the winding groove, and the second handle is continuously pressed to gradually tighten the cable. After being tightened, the cable can be connected by using the cable connecting piece 400, and the cable connecting piece can be locked by using a crimping plier to fix the cable. After being fixed, the locking assembly is opened, and the wound cable is unwound and scattered, and the operation is completed.

[0053] Optionally, the cable connecting piece is two circular rings which are fixedly connected with each other.

[0054] As shown in Figure 13 , the two ends of the cables in different directions need to be crossed and reinforced. One end of the cable is passed through one of the circular rings of the cable connecting piece, and then is inserted from the locking hole (from one side close to the winding wheel to the other side, that is, the free end of the cable is located on the side away from the winding wheel), and is reinforced by using the locking assembly. The other end of the cable is inserted into the other circular ring of the cable connecting piece and is clamped in the winding groove. The second handle is continuously pressed to gradually tighten the cable, and then the cable connecting piece is locked by using a crimping plier to fix the cable. After being fixed, the locking assembly is opened, and the wound cable is unwound and scattered, and the operation is completed. As shown in Figure 14 , the cables in the same direction need to be tightened and reinforced. The method is the same as that of the two ends of the cables in different directions, except that one end of the cable is passed from the side away from the winding wheel to the other side, that is, the free end of the cable is located on the side close to the winding wheel. However, the use method of the wire tightening pliers is not limited in the application, and in another use mode, the middle end of the cable can be clamped on the locking assembly or the middle end of the cable can be clamped on the locking assembly, and the like.

[0055] When the second handle 4 moves towards the first handle 3, the second handle drives the pawl reset member 53 to be compressed, when the pawl reset member 53 is compressed to a certain degree, the pawl 52 is further pushed to move, the pawl 52 drives the gear ring to rotate through meshing, the rotation of the gear ring further drives the transmission part 22 to rotate, so that the winding part 21 rotates, the cable can be gradually wound on the outer circumferential surface of the winding part, the cable is gradually shortened to realize the tensioning of the cable. When the second handle is released, the second handle 4 is reset under the action of the reset tension spring 7, and the second handle 4 moves away from the first handle 3. At the same time, the pawl reset member 53 is reset, the pawl 52 is reset, the transmission part does not rotate under the action of the one-way bearing 26 at this time, so that the wound cable is not scattered, and the gear ring and the transmission part are in gear connection. Under the cyclic reciprocating action of the second handle, until the cable reaches the required tension.

[0056] Those skilled in the art should understand that in the disclosure of the present application, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the above terms cannot be understood as a limitation of the present application.

[0057] Although the present application has been disclosed by the preferred embodiments as above, it is not intended to limit the present application, and any person skilled in the art can make some changes and modifications without departing from the spirit and scope of the present application, therefore the protection scope of the present application shall be subject to the scope required by the claims.
