PURPOSE:To improve cutting characteristics and to provide sufficient withstanding in on-site use by containing a cutter blade giving an initial score to an optical fiber between a fiber stopper and a fiber retainer within a cutter box. CONSTITUTION:A pin 2 is mounted through the side plate 1a of a lower case 1. The root part of a cutter arm 3 is mounted freely rotatably to the central part of the pin 2, and a cutter box 4 contained with a cutter blade 5 giving an initial score to an optical fiber core in its leading end part is secured to said arm. The central parts of the arms 6a of fiber retainers 6 are mounted freely rotatably to both sides sandwhiching the arms 3, and abutting parts 6b opening the retainers 6 by abutting on the bottom surface in the right end part of an upper case 7 are provided to the root end parts of said arms 6a. Further, elastic materials are stuck to the bottom surfaces of the fiber retainers 6, so that the optical fiber core is retained by these. The right end part of a leaf spring 8 is secured to the left end part of the case 1 and a fiber stopper 9 is secured to the top surface of this spring 8. |
