Claims

[Claims for Utility Model Registration] 1. A tool mounting attachment has a contact surface that contacts the contact surface of a tool mounting portion on the machine tool side, and a contact surface that protrudes from the contact surface and that fits into the tool mounting portion. A fitting shaft portion that fits into the hole portion is provided, a recess having an inclined inner wall surface is provided on the outer circumferential surface of the fitting shaft portion, and the tool attachment portion is provided with a recess that has an axial direction of the fitting hole portion. A screw hole extending in orthogonal directions is provided through the screw hole, and a screw rod having a tapered engagement shaft portion at the tip thereof is inserted into the screw hole so that the engagement shaft portion protrudes and retracts from the recess of the fitting shaft portion. The threaded rod is driven in forward and reverse directions, and the tapered engagement shaft part is thrust into the recess and slid along the inclined inner wall surface during forward rotation, so that the attachment can be rotated. 1. A tool clamping device adapted to be pulled inward, characterized in that the recess is formed in the shape of a substantially triangular pyramidal hole. 2. The tool mounting attachment has a hollow cylindrical shape, and within this hollow cylindrical tool mounting attachment, a tool drive shaft having a rotational force transmitting portion at the base end and a tool mounting portion at the distal end is supported. A tool clamping device according to claim 1 of the utility model registration claim.
