Technical Field

[0001] The utility model belongs to the technical field of electrician tools, and in particular relates to a cable stripping tool. Background Art

[0002] During the construction of power cables, in order to improve the reliability of the cable joints, it is usually necessary to strip the cable joints before wiring. In the traditional way, cable stripping requires operators to use a utility knife or electrician's knife to strip the cable outer sheath. However, due to the high requirements for on-site operators' cable stripping skills, insufficient experience or improper operation can easily damage the wire core or uneven quality, making it difficult to ensure good conductivity of the cable joints. At the same time, using a blade during cable stripping may injure hands or break, posing a safety hazard. Utility Model Content
