Claims

[Claims for Utility Model Registration] (1) An adapter whose rear end is attached to a spindle and whose distal end is formed with a first fitting portion consisting of either a tapered portion or a tapered recess; a tool body having a cutting edge, and a second fitting portion formed on a rear end surface of the tool body to fit into the first fitting portion when the rear end surface is abutted against the distal end surface of the adapter;
A clamper whose rear end is inserted movably in an axial direction into an insertion hole formed on a distal end surface of the adapter, and whose distal end is removably inserted into an engagement recess formed on a rear end surface of the tool body; , the adapter is inserted into the adapter from its outer periphery toward the mounting hole, and an eccentric portion formed at an end protruding into the mounting hole is fitted into a long groove formed on the outer periphery of the clamper in a direction perpendicular to its axis. The distance between opposing portions of the tool body and the clamper in the direction of movement of the clamper when the tool body is attached to the adapter is defined as the amount of movement of the tool body by one rotation of the lock pin. A quick-change tool holding device characterized by being set smaller than . (2) The quick change engine according to claim 1, wherein the eccentric portion is formed such that an end portion on the side to be fitted into the long groove is elastically displaceable with respect to the lock pin. type tool holding device. (3) The eccentric portion is formed such that the end portion on the side to be fitted into the long groove is elastically deformable.
The quick-change tool holding device described in Section 1.
