に記載のチツプクランプ機構。[Scope of Claim for Utility Model Registration] (1) An insertion hole in which a circular recess with a diameter larger than the inner diameter of the hole is formed in the upper opening on the bottom surface of the chip mounting seat of the holder body in which the hole is bored. A sheet member having a diameter of approximately the same diameter as the hole is placed on the sheet member with its insertion hole communicating with the hole, and the large diameter of the insertion hole is placed at the tip of a cylindrical main body having approximately the same diameter as the hole. The main body of the clamp pin is provided at a position eccentric to the axis of the main body, and the eccentric pin is provided at a position eccentric to the axis of the main body, with the flange interposed therebetween, and the flange is engaged with the large diameter portion of the sheet member. The clamp pin is inserted rotatably around an axis, and a chip serving as a cutting blade is placed on the sheet member by inserting an eccentric pin of the clamp pin into a mounting hole formed in the center of the chip. In a chip clamp mechanism that fixes the chip by rotating a pin and pressing the inner wall surface of the mounting hole of the chip against the side wall of the chip mounting seat with the eccentric pin, the axis of the flange of the clamp pin is aligned with the axis of the flange of the clamp pin. A tip clamp mechanism characterized by aligning the axis. (2) The sheet member is formed into a diamond shape, and the hole and the insertion hole are bored so that the axes of the main body and the flange of the clamp pin are located on a diagonal line of the sheet member. Claim 1
