Description

Technical Field

[0001] The utility model relates to the technical field of cable stripping, in particular to a cable stripping device for building electrical construction. Background Art

[0002] During the construction of building electrical equipment, cables are needed to connect and lay lines. When the cables are connected, the outer sheath covering the outer core needs to be peeled off. Most cable stripping devices are manual circular cutter type, which are slow in use and require multiple circular cuts to completely strip the cable. The work efficiency is low and the cutting quality is poor. Therefore, the removal time of the main insulation of the cable is long, which is time-consuming and labor-intensive, and reduces the work efficiency. In the technical solution disclosed in the patent with the patent publication number CN219739790U and the patent name of the cable stripping device, the blade of the cutting disc is arranged along the length direction of the cable to achieve longitudinal cutting of the cable. The cutting disc can rotate around its own axis, which improves the cutting efficiency. However, during the cutting process, only one opening can be cut in the longitudinal direction of the cable at a time, which affects the stripping efficiency. The cable is only placed in the guide wheel, which is prone to movement, affecting the cutting. Utility Model Content
