Claims

[Scope of utility model registration request]

The first part is pivoted on the proximal side and can be opened and closed on the distal side.
, a second arm, first and second workbenches provided opposite to each other at the tips of the first and second arms, and the first and second workbenches. first and second fiber guide grooves, which are provided in a corresponding manner across the surface of the fiber guide grooves, through which the tape-shaped multi-core optical fiber core wire whose coating is to be cut are passed; and the first fiber guide. A coated edge cutting tool is supported on the first workbench with its cutting edge facing each widthwise end of the groove, and the first and second core wires are placed on the first and second workbench. a first provided across the guide groove;
a second cutting tool moving groove, and a cutting tool accommodated in the first and second cutting tool moving grooves with a cutting edge facing in a direction transverse to the width direction of the first and second core wire guide grooves; a first pivotably supported on the first and second workbenches so that the cutting edge can rotate in the direction of the first and second core wire guide grooves;
The second sheathing cutting tool and usually the first and second sheathing cutting tools take a cutting attitude with respect to the sheathing of the tape-shaped multi-core optical fiber core within the movement grooves of the first and second cutting tools. When the tape-shaped multi-core optical fiber is moved relative to each other, the first and second sheathing cutting tools are tilted so that their cutting edges are removed from the coating of the tape-shaped multi-core optical fiber. The first and second loincloth cutting tools are biased in the first and second cutting tool movement grooves so that
, and a second spring.
