Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber cutters, in particular to an optical fiber cutter structure with delayed return of the cutter. Background Art

[0002] A fiber optic cutter is a device used to precisely cut optical fibers. Its main function is to ensure the flatness of the fiber end face, which is crucial to the performance and transmission efficiency of optical fiber connectors. Fiber optic cutters are mainly used to cut single-core or multi-core quartz bare optical fibers. The material of optical fibers is generally quartz, a brittle solid material. The fiber end face after cutting must be flat and must have no obvious defects after being magnified hundreds of times before it can be used for device packaging, cold splicing, and discharge welding. Place the optical fiber in the V-groove of the cutter and secure it with a clamp. The outer sheath and coating of the optical fiber must be stripped off before placement.

[0003] When using existing fiber optic cutters, they all return to the knife mode instantly after opening the top cover. The instantaneous return of the knife will affect the cutting effect of the optical fiber. At the same time, because the optical fiber is very fragile, conventional fiber optic cutters often require one hand to fix the fiber optic cutter and the other hand to push the cutting module to drive the cutter to move to cut the optical fiber. Conventional fiber optic cutters are not stable enough when operated with only one hand, so it is easy to cause the optical fiber to break. In addition, the optical fiber is very thin and almost transparent. If the fiber optic cutter does not have a fiber optic waste storage box, the fiber optic waste container will easily pollute the environment and pose a threat to the personal safety of the operator. Utility Model Content

[0004] The purpose of the utility model is to provide a fiber optic cutting knife structure with delayed return, which delays the sliding of the slider on the slide through the meshing operation of the spur gear and the damping gear, thereby realizing delayed return and improving the situation of too fast return. A waste box is installed on one side of the fixed plate, and the fiber optic waste after cutting falls into the waste box for collection, thereby avoiding pollution to the environment caused by the fiber optic waste after cutting and affecting the personal safety of the operator.
