Claims

[Scope of utility model registration request]

It is a pincer-like tool made of two members that intersect with each other around an axis and can rotate with each other, with two parallel semicircular grooves on one side on the surface of each member that overlaps and faces the tip from the axis. 7 in the longitudinal direction, further comprising a fixed sharp cutting blade 4 projecting in the groove direction between the two grooves on one of the members, and on one side of the other one. is provided with one semicircular groove 8 in the longitudinal direction, and in the center of the one semicircular groove 8 is provided with a circular or semicircular cutting blade 15 fixed so as to protrude in the groove direction, Further, on one of the opposing and overlapping surfaces at the rear end of the shaft, a pin 17 is provided in the center of the surface, the amount of feeding being adjustable in a direction perpendicular to the longitudinal direction. Internal and external line cutting tool.
