Optical fiber cutter

An optical fiber cutter comprising:

• a device main body that includes a lid rotatably mounted with respect to a base and that grips an optical fiber;
• a first gripping mechanism comprising:
• a first lower gripper disposed on a lower gripping member;
• and
• a first upper gripper disposed on the lid;
• a second gripping mechanism comprising:
• a second lower gripper disposed on the lower gripping member;
• and
• a second upper gripper disposed on the lid, wherein
• the second gripping mechanism faces the first gripping mechanism in a longitudinal direction of the optical fiber;
• a movable blade member that scratches a surface of the optical fiber gripped between the first lower gripper and the first upper gripper from the base;
• and
• a pressing portion that presses the optical fiber scratched by the blade member to cut the optical fiber, wherein
• the first lower gripper is separate from the base and is rotatable about a rotation fulcrum of the first lower gripper,
• a rotation fulcrum of the first upper gripper is paired with the rotation fulcrum of the first lower gripper and is on a same center line as the rotation fulcrum of the first lower gripper,
• a rotation fulcrum of the second lower gripper is a rotational center common to the first lower gripper and the second lower gripper,
• the lower gripping member includes the rotation fulcrum of the first lower gripper on a base end of the lower gripping member,
• the base includes a displacement mechanism that displaces a distal end of the lower gripping member opposite to the base end of the lower gripping member, and
• the displacement mechanism includes a vertical member that is vertically movable and a manipulating knob that manipulates the vertical member.
