The present invention relates to a feeder cutter that is capable of cutting the cross section of the coaxial cable held by the fixing unit smoothly through the rolling operation of the cutting unit.

In general, coaxial cables are installed for communication purposes such as communication base stations, and such coaxial cables have insulators positioned between inner conductors and outer conductors having different diameters, and coated wires are wrapped on the outer surface of the outer conductors.

The coaxial cable is cut to a certain length and then coupled to a separate connector to a separate connector is connected to the communication equipment of each base station, the method of cutting the coaxial cable is usually used by the operator directly cut the saw directly have.

In the case of cutting using the saw, when cutting the coaxial cable by sawing, the surface of the cutting part is very irregular and rough, and the material is not only attached to the outer surface, but also cut in the direction perpendicular to the longitudinal direction of the coaxial cable. Since it is not possible to cut in an oblique shape and to perform additional foreign matter removal and finishing work, the work time is excessively required, and even after such foreign matter removal work, foreign matter remains on the cutting surface, thereby deteriorating electricity conduction efficiency.
