ABSTRACT:
A spindle centered on an axis and formed with an axially forwardly open recess centered on the axis is secured to a tool holder formed with a tubular extension projecting axially rearward and fitted complementarily in the recess by a mount having an actuating rod axially displaceable in the spindle and having a head in the recess formed with an inner frustoconical surface directed rearward toward the collar and an outer annular surface generally perpendicular to the axis and also directed rearward toward the collar. A retaining element on the rod in the tubular extension has a plurality of segments forming a frustoconical inner front face directed forward toward the head, an outer annular face generally perpendicular to the axis and also directed forward toward the head, and a rear face directed axially rearward. A sleeve axially displaceable on the rod has a front face engageable with the rear face of the segments and a spring braced between the spindle and the sleeve biases the sleeve axially forward against the segments. The rod can be displaced axially rearward to press the segments rearward against the sleeve and cam the segments radially outward into an outer position with the front face of the segments bearing against the rear face of the head and the rear face of the segments bearing axially rearward against the collar.
