Dieser läßt sich mit einem Aufsetzfuß 6 auf das Werkstück 7 aufsetzen, in seiner Führungsbohrung 8 ist die Schrauberklinge 9 achsial verschiebbar gelagert. Zwischen einem Flansch 10 von Führungshülse 4 und Lagerkörper 5 ist eine Druckfeder 11 angeordnet.The screwdriver attachment 2 consists in a known manner of a guide sleeve 4, in which a bearing body 5 is slidably mounted. This can be placed on the workpiece 7 with a mounting foot 6, the screwdriver blade 9 is mounted axially displaceably in its guide bore 8. A compression spring 11 is arranged between a flange 10 of the guide sleeve 4 and the bearing body 5.

Die Schrauben 12 sind mit einem Haltegurt 13 zu einem Schraubenstreifen 14 verbunden, der in einem Magazin 15 spiralig aufgerollt gespeichert ist. Eine Vorschubvorrichtung 16 am Lagerkörper 5 dient dem Vorschub der Schrauben 12 unter die Schrauberklinge 9.The screws 12 are connected to a holding belt 13 to form a screw strip 14 which is stored in a magazine 15 rolled up in a spiral. A feed device 16 on the bearing body 5 serves to feed the screws 12 under the screwdriver blade 9.

Das Verlängerungsrohr 3 ist an seinem werkstückseitigen Ende mit einer Endhülse 17 verbunden, die in einer Bohrung 18 von Führungshülse 4 eingreift und mittels einer Schraube 19 an der Führungshülse 4 festgeklemmt wird.The extension tube 3 is connected at its workpiece end to an end sleeve 17 which engages in a bore 18 of the guide sleeve 4 and is clamped to the guide sleeve 4 by means of a screw 19.

Am antriebsseitigen Ende des Verlängerungsrohrs 3 ist ein Klemmstück 20 befestigt, das mit seiner Bohrung 21 mit einer Schraube 19 auf ein Zwischenstück 22 festgeklemmt wird. Das Zwischenstück 22 ist mit einem Gewindeschaft 23 versehen, auf den die verschiedenen handelsüblichen Antriebseinheiten 1, wie z.B. alektrisch oder pneumatisch betriebene Bohrmaschinen, aufgeschraubt werden können.At the drive end of the extension tube 3, a clamping piece 20 is fastened, which is clamped with its bore 21 with a screw 19 onto an intermediate piece 22. The intermediate piece 22 is provided with a threaded shaft 23 on which the various commercially available drive units 1, e.g. electrically or pneumatically operated drills, can be screwed on.

Das Klemmstück kann zweckmäßigerweise mit einem Handgriff 24 versehen sein.The clamping piece can expediently be provided with a handle 24.

Die Verbindung zwischen dem Achsstummel 25 der Antriebseinheit 1 und der Schrauberklinge 9 erfolgt über eine Verlängerungsstange 26. Diese weist an ihrem werkstückseitigen Ende einen Innensechskant 27 auf, in den der Sechskantzapfen 28 der Schrauberklinge 9 eingreift. Am antriebseitigen Ende ist die Verlängerungsstange 26 mit einem Zwischenglied 29 verschraubt, dessen Sechs- kantzapfen 30 in den Innensechskant 31 von Achsstummel 25 eingreift.The connection between the stub shaft 25 of the drive unit 1 and the screwdriver blade 9 takes place via an extension rod 26. This has an internal hexagon 27 at its workpiece end, into which the hexagon pin 28 of the screwdriver blade 9 engages. At the drive end of the extension rod 26 is screwed with an intermediate member 29, the six k antzapfen 30 into the hexagon socket 31 engaged by shaft stubs 25th

Zum Betrieb des Einschraubgeräts wird dieses mit seinem Aufsetzfuß 6 auf das Werkstück 7 aufgesetzt und die Antriebseinheit 1 eingeschaltet, so daß Schrauberklinge 9 über Verlängerungsstange 26 in Drehung versetzt wird. 0bt jetzt der Bedienungsmann auf die Antriebseinheit 1 und damit über das Verlängerungsrohr 3 auf die Führungshülse 4 eine Kraft in Richtung Werkstück 7 aus, so verschiebt sich die Führungshülse 4 und damit auch dieSchrauberklinge 9, die die erste Schraube 12 vom Haltegurt 13 trennt und ins Werkstück 7 einschraubt.To operate the screw-in device, it is placed on the workpiece 7 with its mounting foot 6 and the drive unit 1 is switched on, so that the screwdriver blade 9 is rotated via the extension rod 26.
