[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Usually, a cable is made of one or more mutually insulated conductors and an outer insulating protective layer, which transmits electricity or information from one place to another; or a rope-like cable made of several or several groups of wires (at least two in each group), each group of wires is insulated from each other and often twisted around a center, and the entire outside is covered with a highly insulating covering.

[0052] Furthermore, through the transmission mechanism, the cutter disc and the cutter disc assembly connected to the transmission mechanism can be moved in the direction where the cable outer sheath is to be stripped, thereby ensuring smooth stripping of the cable outer sheath and avoiding the problems of low efficiency and inaccurate movement of the cutter disc and the cutter disc assembly by manual movement.

[0054] Furthermore, by setting the blade to an arc-shaped structure, the blade can fit the cable well when stripping the cable outer sheath, making the stripping of the cable outer sheath cleaner and avoiding the situation where the outer sheath is too thick or too thin when stripping.

[0055] Furthermore, by providing a baffle structure on the blade, the stripped cable outer sheath is prevented from entering the cutter disc and causing cutter disc failure, thereby ensuring smooth stripping of the cable outer sheath and safe and smooth operation of the device of the present invention.
