Description

Technical Field

[0001] The utility model belongs to the field of electrician tools, in particular to a wire stripper with a wire twisting function. Background Art

[0002] Wire strippers are one of the commonly used tools for inside electricians, motor repairmen, and instrumentation electricians. They are used to allow electricians to strip the surface insulation layer of the wire head. The automatic wire strippers among wire strippers have the highest stripping efficiency because they integrate the three functions of clamping, cutting and stripping. However, in actual use, the metal wires inside the wires are very easy to spread out after stripping, and usually manual rubbing of the wires is required to twist the spread wires together, which has low production efficiency and needs to be improved.
