Claims

[Scope of claims for utility model registration] (1) A plurality of clamps that grip an optical fiber;
A cutting blade is disposed between the two adjacent clamps and moves horizontally or in an arc in a plane perpendicular to the optical fiber to scratch the optical fiber, and the optical fiber is pushed and bent from the opposite side of the scratch. In the optical fiber cutting device, the optical fiber cutting device is provided with at least one reference straight line in a direction perpendicular to the moving direction of the cutting blade immediately below the optical fiber held by the clamp. Characterized by
Optical fiber cutting device. (2) The optical fiber according to claim 1 of the utility model registration claim, characterized in that a plate is provided on the front outer side of the clamp, which is located at the front, and a reference straight line is provided on the upper surface of the plate. Cutting device.
