Abstract
The invention relates to a screwing head having a device for the automatic uncoupling of the screwdriver (18) when a given screwing-in depth is reached, in which position an edge (R or R') surrounding the screwdriver (18) rests on the component receiving the screw (19) and, by longitudinal displacement of a coupling sleeve (10) counter to spring action, uncouples a coupling between a clamping socket sleeve (2) and the screwdriver exchangeably held in a central receptacle (17), and proposes, to facilitate the exchange of the screwdriver (18), improve guidance and reduce wear, to arrange the central receptacle (17) in a sleeve (8) which is mounted relative to the clamping socket sleeve (2) and can be disengaged therefrom, relative to which sleeve (8) an actuating sleeve (29) sits, which forms an annular portion (30) located in front of the front edge (10') of the coupling sleeve (10), and forms the edge (R) with its lower free end, and which is displaceable counter to spring action, in which displaced position it releases the clamping members (21, 28) for retaining the screwdriver (18).
