Claims

[Scope of claim for utility model registration] A hole is drilled in the chip mounting seat of the holder body,
A clamp pin whose main body is cylindrical and has a rotation pin at a position eccentric to the axis of the main body at the tip is inserted into this hole so as to be rotatable around the axis, and a tip serving as a cutting blade is inserted. The rotating pin of the clamp pin is inserted into the mounting hole formed in the center and placed on the chip mounting seat, and the clamp pin is rotated and the rotating pin is inserted into the mounting hole of the chip. In a chip clamp mechanism for fixing the chip by pressing the inner wall surface against the side wall of the chip mounting seat, a recess is formed along the circumferential direction on the outer periphery of the main body of the clamp pin, and the clamp is attached to the holder main body. An insertion hole is formed that communicates with the recess at the pin tightening position, and a fixing pin that is inserted into the recess and locks the clamp pin from moving in the axial direction can be inserted and removed into the insertion hole. A chip clamp mechanism is provided.
