Claims

[Claims for Utility Model Registration] A cutting tool 3 is attached to one end of the holder 1, and this cutting tool 3 is incorporated into a receiving hole 6 of the holder 1, and has an engaging protrusion 7 at its protruding end. The clamp shaft 4 is installed in the side hole 13 so as to be substantially orthogonal to the clamp shaft 4 in a misaligned manner, and is attached and detached by the cooperation of the operating shaft 5 that moves the clamp shaft 4 in the axial direction. In the quick change tool, the cutting tool 3 is provided with a center hole 3a for receiving cutting oil from the holder 1 side and for receiving a tool such as a center drill. 4, a through hole 10 communicating with the center hole 3a of the cutting tool 3 is bored in the shaft centerline portion, and a portion intersecting the operating shaft 5 is formed at an inclination angle α with respect to the axial direction. A concave notch 9 having a key groove 8 is provided, and the operating shaft 5 has a key 17 in its central portion that fits into the key groove 8 in the concave notch 9 of the clamp shaft 4. It is provided convexly, and at one end,
A quick change tool characterized in that it is equipped with a rotation screw 16 having left and right threads so that it can move forward and backward within the side hole 13.
