The screwdriving power tool includes a hollow spindle (8) rotatably
supported in the tool housing (4) and driven by a motor (26), a clutch
(30) that rotatably connects and disconnects the hollow spindle (8) with
and from the motor (26), respectively, in engagement and disengagement
positions of the clutch (30), a screwing-in spindle (6) connected with a
chuck (10) for a working tool (12) and connected with the hollow spindle
(8) for a joint rotation therewith and for an axial displacement relative
thereto, and a percussion mechanism (14) for applying a pulsed axial
force to the screwing-in spindle (6), with the clutch (30) being brought
into its engagement position by the screwing-in spindle (6) by being
displaced against a biasing force of the clutch springs (40, 44), and
being locked in its engagement position.
