ABSTRACT:
A chuck has a chuck body rotatable about a chuck axis and provided with a plurality of jaws which can be radially displaced toward one another by rotation of a tightening sleeve on the chuck body in a tightening direction and which can be displaced radially apart by rotation of the tightening sleeve in an opposite loosening direction. A latching pin is displaceable chordally in a blind bore of the chuck body and is urged radially outwardly. This latching pin is engageable between the teeth of an array of radially inwardly directed teeth formed on the tightening sleeve. The spring of the locking pin presses this pin chordally forwardly into engagement with the teeth with the edge defined between the side and end surfaces of the pin fitting between two adjacent teeth and the end surface flatly engaging one of the front flanks with the side surface engaging the back flank of the tooth immediately trailing this one back flank in the loosening direction. An unlocking element can be rotated on the chuck to displace the locking pin chordally inwardly out of engagement with the teeth.
