Claims

[Scope of utility model registration request]

An optical fiber cutter has a blade for generating initial scratches on the optical fiber core, a fiber clamp and backing plate for fixing the optical fiber, and a leaf spring for bending and cutting, and cuts the optical fiber using tensile force and bending force. A circle that defines the bending shape of a leaf spring that provides a tensile force to the cutting position, and has a cover plate with a notch so that the optical fiber and the optical fiber cutter do not come into contact between the fiber sheathing part and the cutting position. An optical fiber cutter characterized by having an arc-shaped guide plate.
