Optical fiber cutter

摘要

A slider is attached to a cutter main body of an optical fiber cutter in a forward/backward movable state. A round blade member for making a scratch in an optical fiber is attached to the slider in a rotatable state. An operation lever pin for changing over rotation operation modes from one to another is attached to one end side of a pin member which penetrates a wall of the cutter main body. The rotation operation modes include a non-rotation mode for preventing the round blade member from being rotated and a continuous rotation mode for rotating the round blade member by a predetermined angle with every backward movement of the slider.

主权项

1. An optical fiber cutter for cutting an optical fiber, comprising:
a cutter main body having a fiber guide that positions the optical fiber; a slider attached to the cutter main body in a movable state; a round blade member attached to the slider in a rotatable state and arranged to make a scratch in the optical fiber; round blade rotating means that rotates the round blade member; and rotation operation mode setting means that sets any one of a plurality of rotation operation modes including a first mode of restricting rotation of the round blade member, and a second mode of rotating the round blade member by a predetermined angle by the round blade rotating means with every movement of the slider in one direction relative to the cutter main body, and wherein the rotation operation mode setting means comprises an operation lever for changing over the plurality of rotation operation modes from one to another, and a stopper that regulates the movement of the slider in the one direction so as to restrict rotation of the round blade member by the round blade rotating means when the first mode is selected as the rotation operation mode by the operation lever.
