Abstract

Es wird ein Abschaltschrauber mit einer längsverschieb­ baren Schrauberspindei, einer durch diese Längsverschie­ bung ein- und ausrückbaren Trennkupplung und einer Drehmomentüberrastkupplung zum Abschalten der Antrieb­ sübertragung vom Schraubermotor auf die Schrauberspin­ del vorgeschlagen, bei dem der Einsatz dieser bewährten Kombination "Trennkupplung - Drehmomentüberrastkup­ plung" auch für Winkelschrauber verwendbar gemacht ist. Der Abschaltschrauber ist hierzu mit einem Winkelkopf (3) versehen, der über eine längsbewegliche Kupplung (46) mit der ebenfalls längsbeweglichen Schrauberspindel (15) ver­ bunden ist. Die Schrauberspindel (15) ist dabei gekoppelt mit einer Handhabe (56) zum Einrücken der Trennkupplung (25, 26). In weiterer Ausbildung sind die Handhabe (56) zum Einrücken der Trennkupplung (25, 26) und die Schalthandha­ be (59) zum Ein- und Auschalten des Schraubermotors (5) so kombiniert, daß sie einhändig bedient werden können und zwangsläufig das Einschalten des Schraubermotors (5) vor dem Einrücken der Trennkupplung (25, 26) bzw. das Aus­ schalten des Schraubermotors (5) nach dem Ausrücken der Trennkupplung (25, 26) erfolgt. It becomes a shut-off screwdriver with a longitudinal shift bar screwdriver, one through this longitudinal shift Exercise engaging and disengaging clutch and one Torque lock-up clutch to switch off the drive Transfer from the screwdriver motor to the screwdriver spin del suggested using this proven Combination "separating clutch - torque lockup plung "is also made usable for angle screwdrivers. The shut-off screwdriver is equipped with an angle head (3) provided with a longitudinally movable coupling (46) the also longitudinally movable screw spindle (15) ver is bound. The screw spindle (15) is coupled with a handle (56) for engaging the separating clutch (25, 26). In further training, the handle (56) for Engage the separating clutch (25, 26) and the switching hand be (59) for switching the screwdriver motor (5) on and off combined that they can be operated with one hand and inevitably switching on the screwdriver motor (5) the engagement of the separating clutch (25, 26) or the off switch the screwdriver motor (5) after disengaging the Separating clutch (25, 26) takes place.
