Description

Schraubenzieher mit Nebenklinge. Die Erfindung bezieht sich auf einen Schraubenzieher jener bekannten Art, bei der eine zweite schmale Klinge angebracht ist, die je nach Bedarf hoch- oder niedergebracht wird, so daß mit dem Schraubenzieher die kleinste wie auch die größte Schraube eingedreht werden kann.Screwdriver with secondary blade. The invention relates to a Screwdriver of the known type in which a second narrow blade is attached which is brought up or down as required, so that with the screwdriver the smallest as well as the largest screw can be screwed in.

.Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise :dargestellt.The subject of the invention is shown in the drawing, for example:

In das Heft A wird eine breite Klinge B und eine Hülse D eingeführt, in der sich eine schmale, mit einem Gewind e versehene Klinge C befindet. Auf :den beiden Klingen B und C wird eine Stellmutter E angebracht, deren Gewinde dem Gewinde der Klinge C entspricht. Um eine Verschiebung :der Stellmutter zu vermeiden, wird zu beiden Seiten von ihr je ein Haltestift durch die Klinge B durchgeführt.A wide blade B and a sleeve D are inserted into the handle A, in which there is a narrow blade C provided with a thread e. On: the An adjusting nut E is attached to both blades B and C, the thread of which corresponds to the thread corresponds to blade C. To avoid displacement: the adjusting nut will A retaining pin is passed through blade B on both sides of it.

Wie aus der Zeichnung ersichtlich, sind die Klinge B und die Hülse D im dem Heft A gelagert. Die Stellmutter E wird -derart angebracht, .daß sie mit ihrem Gewinde in das der Klinge C eingreift, so daß sich letztere auf- oder abwärts bewegt, wenn die Stellmutter gedreht wird. Die Klingenbreite kann durch Drehen der Stellmutter verringert oder vermehrt werden. Wird die Klinge C nach auswärts geschoben, so kann sie für sich allein gebraucht, und durch die so gewonnene Breite kann die feinste -Arbeit ausgeführt werden. Befindet sich aber die Klinge C in der Schutzhülse zurückgeschoben, so ist eine Breite hergestellt für den gewöhnlichen Gebrauch.As can be seen from the drawing, the blade B and the sleeve D are stored in the handle A. The adjusting nut E is attached so that its thread engages that of the blade C so that the latter moves up or down when the adjusting nut is rotated. The blade width can be reduced or increased by turning the adjusting nut. If the blade C is pushed outwards, it can be used on its own, and the finest work can be carried out thanks to the width obtained in this way. However, if the blade C is pushed back in the protective sleeve, a width is made for normal use.

Um der verstellbaren Klinge beize Einschrauben eines gewissen Gegenstandes einen guten Halt zu geben, muß sie so beschaffen sein, .daß sie mit ihrem Ende dauernd in der Schutzhülse sitzt.To stain the adjustable blade screwing in a certain object To give a good hold, it must be made in such a way that it lasts with its end sits in the protective sleeve.
