[0002] With the progress of society, optical fiber network has become an indispensable part of modern life. With its high speed, stability and reliability, it makes our life and work more convenient and efficient. In order to ensure the stable operation of the optical fiber network, regular maintenance is required. During the maintenance, a stripping device will be used to strip the optical fiber to facilitate the connection of the optical fiber connector. The existing stripping device is generally a wire stripping pliers type, which can use the cutting edge of the front groove to strip the wire. The structure is simple and the cost of use is low. Generally, the degree of closure of the two pliers cannot be adjusted. When the cutting edge is worn, the through hole formed after the two grooves are closed will become larger, and the cutting effect on the outer skin is poor, which affects the stripping quality. At the same time, it is generally impossible to cut and strip multi-strand optical cables, and the scope of use is small. Utility Model Content
