ABSTRACT:
A driving device for securing fasteners (7) such as nails, staples, etc., which are stored in a magazine (6) to be supplied to an ejection channel (5) provided with an opening (8) closed by a spring biased nose plate (9) elastically held by a spring (14) against the opening (8) of the ejection channel (5) in the nose portion (4) on the side opposite the magazine (6). When jamming occurs between a driving plunger (2) and fastener (7), the nose plate (9) lifts itself against the bias of the spring, whereby jamming is frequently avoided automatically. If jamming occurs nevertheless, the nose plate (9) may be completely removed from the opening (8) of the ejection channel (5) so that the jamming may easily be cleared. Potential jamming situations are often avoided since the nose plate (9) may deflect to partially open the ejection channel (5).
