Claims

[Scope of utility model registration request]

The tool mounting attachment is formed into a hollow cylindrical shape, and within this hollow cylindrical tool mounting attachment, a tool drive shaft having a rotational force transmission section at the base end and a tool mounting section at the distal end is axially supported. , the attachment has an abutted surface that abuts the abutment surface of the tool attachment part on the machine tool side, and a fitting shaft part that protrudes from the abutment surface and fits into the fitting hole of the tool attachment part. A recess having an inclined inner wall surface is provided on the outer peripheral surface of the fitting shaft portion, and a screw hole extending in a direction perpendicular to the axial direction of the fitting hole portion is provided in the tool mounting portion. A screw rod having a tapered engagement shaft portion at its tip end is screwed into the screw hole so that the engagement shaft portion can move in and out of the recess of the fitting shaft portion. The tool clamp is configured to drive the attachment in the forward and reverse directions, and to draw the attachment inward by pushing the tapered engagement shaft into the recess and sliding along the inclined inner wall surface during forward rotation.
