Abstract

Die beschriebene Schraubenhalterung ist sowohl für Hand­ schraubendreher als auch für Schraubendrehwerkzeuge, wie Elek­ troschrauber, geeignet und ermöglicht auch bei beengten Raum­ verhältnissen das Eindrehen von Schrauben (5) mit verschieden geformten Schraubenköpfen. Diese Schraubenhalterung weist eine auf dem Schraubendreherwechselfutter (13) befestigbare Hülse (6) auf, an deren aufweitbarem freien Ende (7) innenseitig zum erfassen des Schraubenkopfes (5a) mindestens eine Ringnut vor­ gesehen ist. Um die Handhabung zu erleichtern, wird die Schrau­ benhalterung auf dem Wechselfutter (13) mit Hilfe einer Druck­ feder (16) in Richtung auf die Schraube (5) vorgespannt. Für den Einsatz bei Schrauben mit stark unterschiedlichem Kopf­ durchmesser können bei der Schraubenhalterung in dem freien Ende der Hülse hintereinander mehrere Ringnuten mit unter­ schiedlichem Durchmesser vorgesehen sein, so daß bei unter­ schiedlichen Schraubenkopfdurchmessern ein Wechseln der Schrau­ benhalterung nicht erforderlich ist. The screw bracket described is both for hand screwdriver as well as for screwdriving tools, such as Elek troicopter, suitable and enables even in confined spaces conditions the screwing in of screws (5) with different shaped screw heads. This screw holder has one sleeve (6) attachable to the screwdriver chuck (13) on, at the expandable free end (7) on the inside for Detect the screw head (5a) at least one annular groove is seen. To make handling easier, the screw holder on the changeable chuck (13) with the help of a pressure spring (16) biased towards the screw (5). For use with screws with very different heads diameters can be in the screw holder in the free End of the sleeve one after the other several ring grooves with under Different diameters can be provided so that at under different screw head diameters a change of the screw bracket is not required.
