Referring to fig. 1 and 2, an extension spring 700 is disposed between the first and second clamp arms 100 and 200, two ends of the extension spring 700 are respectively connected to the first and second clamp arms 100 and 200, and the extension spring 700 can drive the first and second clamp arms 100 and 200 to move away from each other. In the specific implementation process, the first clamp arm 100 and the second clamp arm 200 are both provided with connecting columns, two ends of the extension spring 700 are respectively mounted on the connecting columns, when the two clamp arms are pinched by hands, the extension spring 700 is extended, and when the hands loosen, the extension spring 700 drives the two clamp arms to reset, so that the wire stripper can be recycled.
The working process is as follows: firstly, a wire is inserted into the wire pressing assembly 300 and the traction jaw 620, the first clamp arm 100 and the second clamp arm 200 are manually grasped, in the sliding process of the sliding gear, the wire pressing clamp plate 310 is driven by the transmission frame 321 to press the wire, and the rotary cutter body 410 is cut into an insulating skin of the wire. Meanwhile, the transverse cutter 510 is continuously driven to move, and the insulation sheath of the wire is longitudinally cut from the middle. In the process of the movement of the sliding gear, the protrusions on the sliding gear sequentially press the telescopic rod 421, and the telescopic rod 421 drives the rotary knife body 410 to rotate to cut off the insulation skin space between the two rotary knife sleeves 430. Finally, the pulling jaws 620 remove the severed insulation from the wire.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the present invention.
