Description

Schraubenzieher. Schraubenzieher, deren Schneiden aus zwei federnden, durch eine Spreizvorrichtung einstellbaren Backen bestehen, sind bekannt.Screwdriver. Screwdrivers, the blades of which consist of two springy, exist adjustable jaws by a spreader are known.

Die Erfindung besteht darin, daß die federnden Backen mit einer Hülse verbunden sind, die auf dem Schraubenzieherschaft um eine halbe Drehung drehbar ist der an seinem zwischen die Backen greifenden Ende ellipsenförmig verbreitert ist.The invention consists in that the resilient jaws with a sleeve are connected, which can be rotated on the screwdriver shaft by half a turn the end that extends between the jaws is widened in an elliptical shape is.

In der Zeichnung ist ein solcher Schraubenzieher in einer beispielsweisen Ausführungsform veranschaulicht.Such a screwdriver is shown as an example in the drawing Embodiment illustrated.

Hierbei zeigen die Abb. z und 3 den Schraubenzieher schaubildlich von vorn und seitlich, während Abb. a und q. verschiedene Querschnitte nach Linie A-B der Abb. z und 3 erkennen lassen.Here, Figs. Z and 3 show the screwdriver diagrammatically from the front and side, while fig. a and q. different cross-sections according to line A-B in Fig. Z and 3 can be seen.

Wie hieraus hervorgeht, trägt der an seiner Spitze ellipsenförmig ausgebildete Schaft a des Schraubenziehers an seinem oberen Ende mittels eines in einem Schlitz b geführten Stiftes c eine Hülse d, die um eine halbe Drehung drehbar ist. Die Hülse d hat federnde Backen f, f', zwischen welche das ellipsenförmige Ende des Schraubenzieherschaftes a zu liegen kommt, wodurch es möglich ist, die Backen f.# f' durch Verdrehen der Hülse d auf die gewünschte Entfernung voneinander einzustellen.As can be seen from this, the shaft a of the screwdriver, which is elliptical at its tip, carries a sleeve d at its upper end by means of a pin c guided in a slot b, which sleeve can be rotated by half a turn. The sleeve d has resilient jaws f, f ', between which the elliptical end of the screwdriver shaft a comes to lie, making it possible to adjust the jaws f. # F' by turning the sleeve d to the desired distance from each other.
