Description

Technical Field

[0001] This utility model relates to the field of cable stripping technology, specifically to a cable stripping knife. Background Technology

[0002] In the process of railway electrical engineering construction, the outer sheath of the cable is stripped to expose the core wire, and terminals are made and connected. In the past, this was done manually with an electrician's knife or utility knife. However, it is easy for novice or inexperienced construction workers to cut the insulation sheath of the cable core wire with the knife, resulting in the cable head being scrapped and having to be remade. This reduces work efficiency and wastes cable materials. Sometimes, remaking the cable terminal may result in insufficient length, leading to the cable being scrapped. Utility Model Content
