ABSTRACT:
A drill chuck has a body centered on and rotatable about an axis, a plurality of jaws radially displaceable on the body, and an adjustment ring rotatable but not axially displaceable on the body and having a screwthread engaging the jaws for radially displacing the jaws when the adjustment ring is rotated on the body. A locking sleeve rotatable on the body at most through a small acute angle is axially displaceable on the body between a freeing position and a locking position. The locking sleeve and adjustment ring are formed with axially interengageable teeth that mesh only in the locking position. A spring braced between the locking sleeve and the body urges the locking sleeve into the locking position. A holding ring limitedly axially displaceable on the body is axially engageable with the locking sleeve. A pair of angularly spaced abutments on one of the rings and a part on the other ring permit only limited relative angular movement of the rings between a pair of angularly offset positions. Coupling formations between the rings couple same together for axial movement of the locking sleeve into its freeing position on rotation of the holding ring on the adjustment ring into one of its positions and for opposite axial movement of the locking sleeve into its locking position on rotation of the holding ring on the holding ring into the other of its positions.
