The drilling chuck has clamping jaws (2) which form a receptacle for the drilling tool and are adjustable by a clamping ring (5) guided on the chuck body (6). A retaining ring (13) serves to lock the clamping ring (5), for which purpose the axially displaceable retaining ring (13) is held by a retaining spring (28) in the advanced locking position against the clamping ring (5). A holding ring (16) is connected to the retaining ring (13) via an adjusting device, by means of which the retaining ring (13), during the turning of the holding ring (16) relative to the retaining ring (13), can be displaced between its locking position and an unlocking position releasing the clamping ring (5) for turning. <IMAGE> |
