ABSTRACT:
A holder for a tool or workpiece has a tubular working spindle centered on and rotatable about an axis, an elongated pulling element axially displaceable in the spindle and having a front end provided with holder jaws and a rear end with a forwardly directed face perpendicular to the axis. An actuating body axially displaceable in the spindle forward of the element face has an outwardly directed and rearwardly inwardly inclined face. A spring between the spindle and the body urges the body continuously backward. At least one wedge in the spindle between the body and the element face has a rear end face flatly abuttable with the element face, an inclined inner face flatly abuttable with the body face, and a forwardly outwardly inclined front end face. This wedge is movable between an outer position with its end faces respectively flatly abutting the element and body faces and an inner position with its rear end face flatly abutting the element face and its front end face inward of and out of contact with the body face. A support sleeve fixed in the spindle forward of the element face has a rearwardly directed and rearwardly outwardly inclined face flatly abuttable with the front face of the wedge.
