Claims

[Scope of utility model registration request]

A punch case that holds a punch or a punch holder that supports the punch itself so that it can move forward and backward in the axial direction is moved in a distance direction with respect to a pressed surface of a notch formed on the circumferential surface of the punch case or the circumferential surface of the punch itself. A fixing screw shaft can be screwed through the fixing screw shaft, and a square shaft portion is provided at the outer end of the fixing screw shaft, and a rotation preventing protrusion having a polygonal outer peripheral surface is inserted from the punch holder into the fixing screw shaft. and a polygonal inner peripheral surface for preventing rotation that fits into the protrusion for preventing rotation at one end, and a corner that fits into the square shaft portion of the fitting shaft for fixing at the other end. A cylindrical operating tool having a hole is arranged such that the polygonal inner circumferential surface for preventing rotation fits into the protrusion for preventing rotation, and the square hole fits into the square shaft of the fixing screw shaft. Punch mounting structure in parts former that can be attached and detached like this.
