Abstract
A tool or workpiece having a mounting collar centered on an axis and for internally with an axially directed shoulder is mounted on a bolder having a drive sleeve also centered on an axis and fitted coaxially over the collar and a plurality of angularly spaced jaws in the sleeve having axially outer ends each formed with a rearwardly directed face. The jaws are displaceable radially between an outer locking position with their faces bearing axially inward on the shoulder and an inner freeing position with their faces out of engagement with the collar. An axially displaceable actuating member in the sleeve moves the jaws between their inner and outer positions. Axially extending retaining fingers each have a rear end secured in the sleeve and a front end with a rearwardly directed face. The front ends normally lie in an outer holding position with their faces bearing axially inward on the shoulder and the fingers are elastically deformable into an inner releasing position with their faces out of engagement with the collar.
