Technical Field

[0001] The utility model relates to the technical field of optical fiber clamping and fixing, and particularly relates to an optical fiber cutting knife. Background Technique

[0002] Before fusing an optical fiber, in order to make the fusing end face flat, it is necessary to use an optical fiber cutting knife to cut the end face of the optical fiber; before cutting the optical fiber, it is necessary to peel off the outer skin of the optical fiber, remove the optical fiber coating, clean the debris on the surface of the fiber core with an alcohol cotton ball, then fix the optical fiber, and then use a cutting machine to cut the end face of the optical fiber.

[0003] During cutting, it is necessary to control the cutter head of the cutting machine to gradually approach the side wall of the end of the optical fiber until it contacts and crosses the optical fiber to complete the cutting. Therefore, the distance between the cutter head of the cutting machine and the end of the optical fiber is a relatively important parameter. When this parameter is large, the cutter head needs to move a large distance to contact the optical fiber, and the cutting efficiency is low, and the volume of the entire device will also be affected and increase; when this parameter is small, although the cutting efficiency is effectively improved and the volume of the device is also effectively reduced, the cutter head is relatively close to the optical fiber loading position, and when loading and fixing the optical fiber, it will be affected by the cutter head, and it is easy to obstruct, bump or even damage the optical fiber.
