[0002] During the optical fiber processing process, an optical fiber cutter is required to cut and segment the optical fiber. After cutting, the cut surface of the optical fiber needs to be kept flat. The operation of the existing optical fiber cutter is cumbersome and requires the operator to operate with both hands. In addition, the operator needs to manually switch the blade during the cutting process, which is inefficient.

[0003] In daily use environments, the movement or sliding of the optical fiber during the cutting process will lead to inaccurate cutting position, affecting the cutting quality and performance of the optical fiber. Unstable clamping may cause the optical fiber to break or produce microcracks, which will increase the loss of the optical fiber and reduce the transmission efficiency. Due to cutting errors, the optical fiber may need to be re-clamped and cut, which increases the workload and time cost. Unstable clamping may cause abnormal contact between the cutting knife and the optical fiber, thereby damaging the cutting knife or the workbench. Utility Model Content
