Description

Technical Field

[0001] The utility model relates to the technical field of cable cutting, in particular to a cutting device with a protective function. Background Art

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. It is usually a rope-like cable made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. Usually, the cable needs to be cut during the production process.

[0003] At present, in the prior art, for example, a Chinese patent with a publication number of CN217343364U discloses a cable cutting device based on the construction of power transmission lines. The device accommodates and limits the cables through a limit groove arranged on a platform. The pressing end of the pressing member can cooperate with the limit groove to limit and clamp the cables to avoid position displacement of the cables during the cutting process. The pressure rod on the mounting seat is used to drive the knife seat to move downward, and the knife head at the bottom of the knife seat is pressed into the cutting groove to cut the cable, thereby avoiding the burrs caused by the displacement of the cable and ensuring the cutting quality of the cable. However, during the long-term cutting process, the blade of the cutter will curl, thereby affecting the working efficiency of the device. In view of this, we propose a cutting device with a protective function. Utility Model Content
