[0010] An adjusting structure is provided inside the mounting groove, for driving the first guide rail and the second guide rail to move.

[0011] A driving structure is provided on the front surface of the mounting shell, for driving the adjusting structure to work.

[0012] Preferably, the adjustment structure includes a spur gear rotatably mounted on the inner wall of the mounting groove, and a first rack and a second rack respectively fixedly mounted on the opposite surfaces of the first guide rail and the second guide rail.

[0013] Preferably, both the first guide groove and the second guide groove extend to the lower end of the mounting housing.

[0014] Preferably, both the first and second spur racks mesh with spur gears for transmission.

[0015] Preferably, the blade of the transverse cutting blade is perpendicular to the blade of the longitudinal cutting blade.

[0016] Preferably, the drive structure includes a worm gear rotatably mounted on the front of the mounting housing, a support frame fixedly mounted on the front of the mounting housing, and a worm rotatably mounted on the inner wall of the support frame, and a handle that can drive the worm to rotate is provided on the right side of the support frame.

[0017] Preferably, the worm gear meshes with the worm shaft for transmission.

[0018] Preferably, the back side of the worm gear extends into the interior of the mounting groove and is fixedly connected to the front side of the spur gear.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By setting up a wire stripping structure, the wire is placed inside the wire guide ring. Then, the horizontal cutting blade pierces the wire insulation. Rotating the handle causes the wire guide ring to rotate on the surface of the wire, thus separating the insulation. Next, the vertical cutting blade extends and enters the cutting path of the horizontal cutting blade, moving along the longitudinal direction of the wire to cut through the insulation longitudinally. Then, the horizontal cutting blade extends again to pierce the insulation, and rotating the handle causes the wire guide ring to rotate on the surface of the wire. This allows for quick stripping of the insulation from the wire surface in the middle, making it easy for operators to use.

[0021] 2. By setting an adjustment structure, rotating the worm gear can drive the drive structure to rotate the spur gear. The spur gear meshes with the first and second spur racks to drive the first and second guide rails to move synchronously in opposite directions. This allows adjustment of the position of the transverse and longitudinal cutting blades relative to the wire guide ring, thus enabling the cutting of wires of different diameters.
