ダ。[Claims for Utility Model Registration] An eccentric sleeve comprising an outer cylinder having a generally cylindrical shape and a cylindrical part fitted inside the outer cylinder, and in which the outer peripheral surface and the inner peripheral surface of the cylindrical part are eccentric. a tool holder, which has a shaft portion with a circular cross section that is fitted inside the cylindrical portion of the eccentric sleeve, and holds a cutting tool in a portion that protrudes further forward from the front end of the eccentric sleeve and the outer cylinder; A relative rotation prevention mechanism that allows relative movement of the tool holder with respect to the outer cylinder in the radial direction but prevents relative rotation, and a rotation drive mechanism that rotates the eccentric sleeve, and a rotation drive mechanism that rotates the eccentric sleeve by the rotation drive mechanism. In the tool holder whose cutting tool edge position is adjustable based on the cutting tool, the outer cylinder has a bottomed cylindrical shape with a bottom at the rear end, and the eccentric sleeve has its eccentric A fixed gear concentric with the outer circumferential surface of the sleeve is installed,
A pinion having an axis parallel to the center line of the outer cylinder and meshing with a gear is rotatably held in the outer cylinder, a ratchet wheel is provided concentrically and integrally with the pinion, and the ratchet wheel and the pinion are rotatably held in the outer cylinder. A slide equipped with engaging ratchet pawls is held at the bottom of the outer cylinder in a state where it can move in a direction substantially perpendicular to the center line of the outer cylinder at a position closer to the center line of the outer cylinder than the ratchet wheel, and A tool holder characterized in that the eccentric sleeve is rotated by a constant angle by one reciprocation of the slide.
