Abstract

PURPOSE:To improve the fitting rigidity as well as to quickly load and unload the cutting head by fixing a cutting head through tractive process to the concave part of the notched step of a holder, via a tractive shaft. CONSTITUTION:A recess 5 and a service hole 6 are provided together on the upright wall of a notched step 4 for receiving a cutting head 3 formed on the holder 1, and the convex part 7 of the cutting head 3 is fitted in said recess 5. And, a tractive shaft 9 and a spring 10 are inserted into the service hole 6, and the engaging head part 11 formed on the projection end against the service hole 6 of the tractive shaft 9 is received into the engaging hole 13 of the cutting head 3. Moreover, traveling of the service hole 6 of the tractive shaft 9 in the axial direction is set by the cooporation with a spring 10 subsequent to the going in and out of wedge piece against the side hole 13 of the tractive shaft 9 by making a pair of wedges 14 to come near and to separate from each other by the rotation of a spring member 15.
