Claims

[Claims for Utility Model Registration] (1) A tool device including an adapter fixed to a cutting tool mounting part of a machine tool and a tool holder detachable from the adapter, wherein the tool holder is planar. and a fitting protrusion with a circular cross section protruding from the first adhesion surface, and a circumferential annular groove on the outer peripheral surface of the fitting protrusion and a groove free from the annular groove of the fitting protrusion. an axial groove extending to the end, and both side wall surfaces of the annular groove are tapered surfaces inclined in the same direction; an adapter body having a through hole formed in a radial direction from the fitting hole, and a second contact surface that comes into close contact with the first contact surface; A clamp whose end portion protruding into the fitting hole is capable of fitting into the annular groove and selectively engaging with the inclined both side wall surfaces, and is an engaging portion large enough to pass through the axial groove. and a clamp member drive mechanism that is provided between the clamp member and the adapter body and moves the clamp member forward and backward, and the engaging part is moved in a relative phase in which the engaging part and the axial groove do not match. By being selectively engaged with both side wall surfaces of the annular groove, the tool holder is attracted to and pushed away from the adapter, and the axis of the engaging part is aligned in a relative phase where the engaging part and the axial groove match. A tool device capable of quickly changing a cutting tool, characterized in that the tool holder is attached and detached while passing through a directional groove. (2) Both side wall surfaces of the annular groove formed in the fitting protrusion of the tool holder extend from the free end side of the fitting protrusion toward the axis from the outer peripheral surface of the fitting protrusion. The tool device according to claim 1, wherein the tool device has a tapered surface that slopes toward the end.
