ABSTRACT:
A quick change tool holder of the block tool type wherein a tool nose assembly is releasably secured to a drive member or holder. The tool nose includes a bayonet portion extending axially outward from the rear end thereof which is receivable by an axial opening in a locking assembly housed in the drive member. The bayonet portion is positioned behind a locking ring in the locking assembly, and this locking ring is selectively shiftable axially of the drive member between disengaged and engaged conditions against and under the influence of spring biasing means. In the disengaged condition, the bayonet portion is insertable into and removable from association with the locking assembly. In the engaged condition, the spring biasing means acts against the locking ring to, in turn, act against the bayonet portion for moving the tool nose axially toward the drive member to place teeth on these two components in cooperative engagement to thereby effect a secure interconnection therebetween.
