Description

Der bisher bekannte Schraubenzieher mit Vorrichtung zum Festhalten der Schraube beruht auf einem Prinzip, das nur für geschlitzte Schrauben und ohne Längsverschiebung der Festhaltevorrichtung anwendbar ist.The previously known screwdriver with a device for holding the screw is based on a principle that is only applicable to slotted screws and without Longitudinal displacement of the retaining device is applicable.

Der erfindungsgemäße Schraubenzieher zeichnet sich durch ein auf der Schraubenzieherklinge verschiebbares Rohr aus, das vorn federnde Zungen trägt und das je nach dem zu erfassenden Gegenstand (Schraube mit und ohne Schbitz, Nieten, Muttern oder Unterlegscheiben) in Stellung -gebracht oder auch ganz zurückgeschoben werden kann, wenn der Schraubenzieher ohne die Festhaltevorrichtung Verwendung finden soll. In der Zeichnung ist z. B. der Federsatz zum Festhalten einer Schraube mit Schlitz gezeigt. Die Federzungen a, zwischen die die Schraube geklemmt ist, werden durch Vorschieben der Spannhülse b zusammengedrückt. Der auf der Spannhülse b sitzende kordierte oder geriffelte Knopf c dient zum mühelosen und sicheren Bewegen der Spannhülse b. Zum Freigeben der Schraube wird die Spannhülse b mittels des Knopfes c zurückgeschoben.The screwdriver according to the invention is characterized by a on the Screwdriver blade made of a sliding tube that carries spring tongues at the front and depending on the object to be detected (screw with and without Schbitz, rivets, Nuts or washers) brought into position or pushed back completely if the screwdriver can be used without the retaining device target. In the drawing, for. B. the spring set for holding a screw with Slot shown. The spring tongues a, between which the screw is clamped, are compressed by advancing the clamping sleeve b. The one sitting on the adapter sleeve b Corded or grooved button c is used to move the clamping sleeve effortlessly and safely b. To release the screw, the clamping sleeve b is pushed back by means of the button c.

Der gewerbliche Vorteil liegt in der Zeitersparnis beim Anbringen und Entfernen von Schrauben u. d@gl. an schwer zugänglichen Stellen.The commercial advantage lies in the time it saves when installing and removing screws and the like. in hard-to-reach places.

Claims (3)
