Abstract

A thrust mechanism for screwdriving devices is proposed which has a screwdriver spindle movable in its longitudinal axis. The screwdriver spindle is driven by means of an electric motor. When the screwdriver spindle strikes the screw to be tightened, a spring system which presses the screwdriver spindle against the screw is stressed. A control pin, which acts on a transmitter which, for its part, transmits pulses for control electronics, can be moved simultaneously by the spring system. <IMAGE>
