[0003] In related technologies, wire strippers include two rotatably connected jaws, each jaw being fixedly connected to a handle, and both jaws having stripping grooves for stripping wires.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: when it is necessary to strip wires of different outer diameters, the wire strippers of the aforementioned technologies are difficult to handle. Utility Model Content

[0005] In order to enable wire strippers to strip wires of different radii, this application provides a wire stripper.

[0006] The wire stripper provided in this application adopts the following technical solution:

The first blade and the second blade are rotatably connected to the first jaw, and a stripping space is formed between the first blade and the second blade. The stripping space communicates with the jaw jaw. The wire stripper includes a positioning device for positioning the relative positions of the first blade and the second blade.

[0008] By adopting the above technical solution, the angle between the first blade and the second blade is positioned by the positioning device, thereby realizing the adjustment of the stripping space between the first blade and the second blade, so that it can adapt to stripping wires with different outer diameters.

[0009] Preferably, the positioning device includes a sliding block and a limiting bolt. The first jaw has a dovetail groove. The sliding block is located in the dovetail groove. The limiting bolt is threaded to the sliding block, and the tail of the limiting bolt abuts against the bottom of the dovetail groove. The limiting bolt is located between the first blade and the second blade, and the head of the limiting bolt is in contact with both the first blade and the second blade.

[0010] The angle between the first and second blades can be adjusted by adjusting the position of the sliding block and the limiting bolt. Tightening the limiting bolt positions the sliding block, and loosening the limiting bolt releases the sliding block for adjustment. The structure is simple.

[0011] Preferably, the wire stripper includes a positioning part, the positioning part having a first contact wall and a second contact wall, the positioning part and the second jaw, and the first contact wall and the second contact wall forming a positioning space, the positioning space, the wire stripping space and the jaw are all connected.

[0012] By setting the first contact wall and the second contact wall, the wire can be pre-positioned, making the wire more stable and easier to strip during the process.

[0013] Preferably, the positioning part includes a first cylinder and a second cylinder, the first cylinder having a first contact wall and the second cylinder having a second contact wall, and both the first cylinder and the second cylinder being rotatably connected to the second jaw.

[0014] By rotating the first cylinder and the second cylinder with the second jaw, wear between the first and second blades and the positioning part can be reduced, thus extending the service life of the first and second blades.

[0015] Preferably, the clamp body includes a first handle, a return spring, and a second handle. The first handle is connected to the first jaw, the second handle is connected to the second jaw, the first jaw and the second jaw are rotatably connected, the return spring is located between the first handle and the second handle, one end of the return spring is connected to the first handle, and the other end of the return spring is connected to the second handle.

[0016] The reset spring design allows the first and second handles to reset after wire stripping, improving ease of use.

[0017] Preferably, the wire stripper includes a fixing bolt that passes through the first blade and the second blade, and the tail of the fixing bolt is threaded to the first jaw, and the head of the fixing bolt is used to abut against the first blade or the second blade.

[0018] By using fixing bolts, the relative positions of the first and second blades can be fixed, reducing the occurrence of relative rotation between the first and second blades during wire stripping.

[0019] Preferably, the wire stripper includes a bearing, the outer ring of the bearing is fixedly connected to the first jaw, the first blade and the second blade are rotatably sleeved on the outer ring of the bearing, and the fixing bolt is located on the inner ring of the bearing.

[0020] By using bearings, the occurrence of rotating the fixing bolts and driving the first or second blade can be reduced.

[0021] Preferably, a contact portion is fixedly connected to the fixing bolt, the contact portion is located between the head of the fixing bolt and the first blade, the contact portion is fixedly connected to the head of the fixing bolt, and the contact portion abuts against the first blade.
