摘要

The pneumatic screw driver includes a supply arm (4) for feeding screws individually from a supply to the screw driver channel. This supply arm has a front arm section (5) which is swivel mounted about an axis (21), and an axially movable rear arm section (6). In the screw supply position the two arm sections adjoin one another in alignment. To swivel the front arm section the rear section can be moved axially back up to a stop (14), preferably through compressed air.
