Description

Die bisher gebräuchlichen Schraubenzieher litten unter dem Nachteil, daB sie dauernd abrutschten und dadurch das zu bearbeitende Werkstück beschädigtem. . . ., Diesen Übelstand beseitigt die Erfindung. Sie besteht darin, daß über den vorderen Teil der Schraubenzieherklinge eine zurückfedernde Hülse geschoben ist, die die einzuschraubende Schraube umfaßt. Dadurch wird das Einziehen der Schrauben schneller und sicherer besorgt. Ein Abgleiten der Klinge an der Schraube ist nicht mehr möglich.The previously used screwdrivers suffered from the disadvantage that they kept slipping off and thereby damaged the workpiece to be machined. . . ., The invention eliminates this drawback. It consists in the fact that about the a spring-back sleeve is pushed into the front part of the screwdriver blade, which includes the screw to be screwed. This will tighten the screws worried faster and safer. The blade does not slide off the screw more is possible.

Der Erfindungsgedanke kann auch in Bohrwinden und Drillbohrern verwirklicht werden, wodurch ein noch schnelleres Arbeiten von Massenverschraubungen gewährleistet wird.The concept of the invention can also be implemented in drill jacks and drill bits which ensures that bulk screw connections can be carried out even more quickly will.

Zweckmäßigerweise versieht man die Hülse am unteren Ende mit einem Kontrollschlitz, um jederzeit feststellen zu können, wie weit die Schraube eingeschraubt ist.Appropriately, one provides the sleeve at the lower end with a Control slot to be able to determine at any time how far the screw is screwed in is.

Die Abbildungen zeigen ein Ausführungsbeispiel der Erfindung.The figures show an embodiment of the invention.

Abb. i ist eine Ansicht mit Schnitt; Abb. 2 zeigt eine Einzelheit.Fig. I is a sectional view; Fig. 2 shows a detail.

i ist die zurückfedernde Hülse, die über die einzuziehende Schraube gesteckt wird, 2 ein Kontrollschlitz, 3 die Schraubenzieherklinge, 4 die Klingenschneide, 5 eine Hülse, in der die zurückfedernde Hülse i auf und ab gleitet, 6 der Raum zur Aufnähme der Druckfeder 7 und 8 der Holzgriff des Schraubenziehers.i is the spring-back sleeve that goes over the screw to be retracted is inserted, 2 a control slot, 3 the screwdriver blade, 4 the blade edge, 5 a sleeve in which the resilient sleeve i slides up and down, 6 the space for Recording of the compression spring 7 and 8 of the screwdriver's wooden handle.

Die Wirkungsweise ist folgende: Der Schraubenzieher wird mit seiner Hülse i auf die einzuziehende Schraube gesteckt und heruntergedrückt. Dabei wird die Schraubenzieherklinge 3 in den Schlitz der Schraube gedrückt. Die Hülse i umschließt die Schraube und läßt sie während des Arbeitsganges nicht mehr los.The way it works is as follows: The screwdriver is used with his Sleeve i placed on the screw to be pulled in and pressed down. It will the screwdriver blade 3 pressed into the slot of the screw. The sleeve i encloses the screw and does not let go of it during the operation.

Durch den Kontrollschlitz 2 läßt sich jederzeit feststellen, wie tief die Schraube eingeschraubt ist.The control slot 2 can be used to determine at any time how deep the screw is screwed in.
