摘要

The object of the invention is in a hand-held device with Drehschlagbohr against a restoring force axially movable drill spindle, the drill spindle in a simple manner and with little effort set for the drilling operation, while at the same time to prevent the connection of the striking mechanism.; This object is inventively achieved in that the drill spindle (16) frees in its relaxed position an engagement gap (28) for a bracket (29) which is pivotably mounted in the transmission housing (14) under the action of a spring (34), by means of a toggle lever (31) operable to prevent axial movement of the drill spindle in the operating case and the hammer mechanism is disengaged from the drive shaft (7) stops (Figure 1).
