Abstract: A power screwdriver (1) with a rotationally driven, axially displaceable mounted tool spindle (2) with a low-noise torque clutch (3) which comprises a ratchet-spring biased ratchet coupling (6) driven by a driven ratchet part (12) and a rigid slack clutch spring (7) biased claw coupling (8). The ratchet coupling (6) and the claw coupling (8) are combined using a common, axially displaceable, freely rotatable coupling sleeve (9). The ratchet coupling (6) has opposing oriented, peripheral inclined beveled cams (10) and the claw coupling (8) has opposing oriented catches (11). The driven ratchet part (12) and the coupling sleeve (9) are arranged freely rotatably on an intermediate sleeve (13), which is mounted freely rotatable and axially displaceable on the tool spindle (2). The ratchet spring (5) is arranged between the intermediate sleeve (13) and the coupling sleeve (9) and the clutch spring (7) is arranged between the intermediate sleeve (13) and the tool spindle (2).

Abstract: A drill chuck for a hand-held drilling device, such as a hammer drill, percussion drill or the like, includes a chuck body mounting a plurality of clamping jaws. An adjusting sleeve is rotatably mounted on the chuck body for positioning a partly frusto-conically shaped bracing sleeve for radially positioning the clamping jaws to secure or release a tool shank. The adjusting sleeve includes gear teeth which can be engaged by a ring gear key for rotating the adjusting sleeve relative to the chuck body. A locking sleeve is axially displaceably mounted on the adjusting sleeve. In a first position, the locking sleeve blocks engagement of the key with the ring gear teeth. In a second position, the locking sleeve is moved affording access by the key to the ring gear teeth so that the adjusting sleeve can be rotated and the clamping jaws radially positioned by the bracing sleeve.
