Description

Technical Field

[0001] The utility model relates to the technical field of shearing pliers, in particular to a cutting device suitable for cables. Background Art

[0002] Cable cutters are tools specially designed for cutting cables. When using cable cutters, you only need to place the cable between the cutting blades and then press the handles together to easily cut the cable. This tool is suitable for cutting thicker or harder cables, such as power cables, communication cables, etc.

[0003] When using cable cutters to cut cables, the shearing blades of the cable cutters will exert a concentrated shearing force on the cables when they are closed, causing pressure on the cables at the shearing points. Due to the elastic and plastic properties of the cables, the cables will deform and displace to a certain extent when subjected to shearing force, causing the cables to warp on both sides of the shearing blades. This warping phenomenon may change the actual cutting position of the cable by the cutters, resulting in inaccurate cutting. In addition, the warping may increase the resistance during the cutting process, making cutting more difficult, and may even cause the shearing blades to get stuck or damaged. In addition, the warping of the cable during cutting may also cause the cable end face to be uneven after cutting, affecting subsequent connection or processing. Utility Model Content
