Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a cable cutting device for electrical engineering installation. Background Art

[0002] In the wiring process of the electrical cabinet, a large number of wires are needed to connect the terminals of various electrical components. Since the spacing between the terminals is different, if the wire is too long, it will easily lead to problems such as chaotic wiring and wire entanglement. If the wire is too short, the two terminals cannot be connected. Therefore, it is necessary to cut the wire according to the spacing between the two terminals so that the length of the wire is suitable for the wiring work of the electrical cabinet.

[0003] However, traditional cutting tools cannot measure the length of the wire, and are prone to cutting too much or too short. At the same time, manual pulling is required and the wire is prone to skew, resulting in large errors in length measurement. To this end, we propose a cable cutting device for electrical engineering installation to solve the above problems. Utility Model Content
