[0002] Wire crimping pliers, also known as wire crimping pliers, are mainly used for crimping the connectors of network cables and telephone cables, such as connecting crystal heads or cutting and stripping cables. They are widely used in telephone and computer line connections. Wire crimping pliers are comprehensive and constantly innovating, and a variety of new functions and types have been developed, such as rechargeable crimping pliers, rechargeable hydraulic crimping pliers, and manual integral crimping pliers. Among them, manual crimping pliers are suitable for simple wire cutting, insulation stripping, etc. Manual crimping pliers in the prior art generally have the same cutting edge for both stripping and shearing. It is more difficult to cut or strip slightly thicker wires, and the operation is not convenient. At the same time, the diameter of the stripping opening cannot be adjusted for wires of different diameters, which can easily damage the cable core. Utility Model Content

[0004] The utility model provides a labor-saving wire crimping pliers, comprising a first handle, a second handle, a first pliers head, a second pliers head, a first connecting assembly and a second connecting assembly; the first pliers head and the second pliers head are rotatably connected by the first connecting assembly; the first handle and the second handle are rotatably connected by the second connecting assembly; the first handle is fixedly connected to the first pliers head; the second handle and the second pliers head are fixedly connected; a first wire cutting opening is provided on the outer side of the first pliers head; a first cutting blade is provided on the other side; a second wire cutting opening is provided on the outer side of the second pliers head, and a second cutting blade is provided on the other side; by gripping the first handle and the second handle, the first cutting blade is caused to cut toward the second wire cutting opening; and the second cutting blade is caused to cut toward the first wire cutting opening.
[0005] The present invention's wire crimping pliers utilize side-cutting rather than top-jawed cutting, resulting in a shorter torque and greater labor savings. Furthermore, the first cutting blade is integrally formed with the first pliers head, and the second cutting blade is integrally formed with the second pliers head, eliminating the need for additional space. The overall structure is compact, and the side-cutting can be operated simultaneously with the jaws. During side-cutting, the process of gripping is the same as the cutting process.
[0006] Furthermore, the jaws of the first pliers head are provided with a plurality of semicircular first wire stripping openings; the jaws of the second pliers head are provided with a plurality of second wire stripping openings; the first wire stripping openings and the second wire stripping openings match to form a plurality of circular wire stripping holes.
[0007] In order to realize the wire stripping function of the wire crimping pliers, the jaws of the first pliers head and the second pliers head of the utility model are respectively provided with a semicircular first stripping opening and a second stripping opening, and different circular stripping holes can be selected according to the diameter of the wire.
[0008] Preferably, the number of the circular wire stripping holes is 2 to 5, and the diameter increases from the top end to the tail end.
[0009] More preferably, in one embodiment of the present invention, the number of the circular stripping holes is 3 to 4, and the diameter increases from the top to the tail. In one embodiment of the present invention, the number of the circular stripping holes is 3.
[0010] Furthermore, the second connecting assembly includes a torsion spring and a first latch; the two ends of the torsion spring are respectively in contact with the inner walls of the first handle and the second handle; the first latch is used to connect the first handle, the torsion spring and the second handle; when the first handle and the second handle are tightened, the torsion spring is compressed, so that the jaws of the first pliers head and the second pliers head, the first wire cutting mouth and the second wire cutting mouth are closed; when the first handle and the second handle are loosened, the jaws of the first pliers head and the second pliers head, the first wire cutting mouth and the second wire cutting mouth are opened under the rebound action of the torsion spring.
[0011] The utility model utilizes the opening and closing of the handle to control the opening and closing of the pliers head. Preferably, a torsion spring connection mode is adopted, and the natural resilience of the torsion spring can be utilized to realize the opening of the first handle and the second handle, which is more labor-saving and simple to operate.
[0012] Furthermore, a first connecting portion is provided on the inner side of the first handle, and a second connecting portion is provided on the inner side of the second handle; the second connecting portion is embedded in the first connecting portion, and the upper end of the first connecting portion is rotatably connected to the second connecting portion through the first pin.

[0014] In order to prevent the first and second handles from being spread apart during storage or carrying, which may cause the first and second pliers to separate, the present invention also designs a rivet that can fix the first and second handles. When gripping, the rivet is slid upward and embedded into the locking groove on the second connecting portion, so that the first and second handles are fixed by the rivet. Alternatively, when gripping, the first and second pliers are facing downward, and under the action of gravity, the rivet can slide into the installation position along the first sliding groove. At this time, due to the resilience of the torsion spring, the rivet can be stably stuck in the locking groove under the action of the lateral tensile force on both sides. By firmly gripping the first and second handles again, the lateral tensile force on both sides of the rivet disappears, and the rivet slides out of the locking groove under the action of gravity, thereby unlocking the first and second handles.
[0015] Furthermore, the first connecting assembly includes a central male screw, a first washer, a second washer and a central female screw; the central male screw passes through the first washer, and the central female screw passes through the second washer, the first clamp head, the second clamp head and is connected to the central male screw.

The positions of the central female screw and central male screw can be interchanged, and this is within the scope of protection of this utility model. Furthermore, the first handle is fixedly connected to the first pliers by a second latch, and the second handle is fixedly connected to the second pliers by a third latch.
[0017] Preferably, both ends of the first latch, the second latch and the third latch of the present invention are provided with retaining rings.
[0018] Preferably, the labor-saving crimping pliers of the present invention further include two sets of anti-slip handles, wherein mounting positions are provided inside the anti-slip handles, and the first handle and the second handle are respectively embedded in the mounting positions of one set of the anti-slip handles.
[0019] The first and second handles of the present invention are square in structure and are detachably connected to the anti-slip handle in an insertable manner, preventing the anti-slip handles from slipping relative to the first and second handles when applying force. The insertable installation method also facilitates replacement of the anti-slip handles.
[0020] Furthermore, the outer side of the anti-slip handle is provided with transverse anti-slip grooves; the anti-slip handle is provided with a patch slot, and the patch slot is provided with a nameplate patch. To better meet the requirements of human ergonomics, the anti-slip handle of this utility model has the area with the transverse anti-slip grooves protrude outward to form a certain arc, which can increase the contact area with the hand. The nameplate patch is also designed in this utility model, which can be customized according to requirements.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] The side-cutting design of these labor-saving crimping pliers allows for side-cutting, saving even more effort.
