Abstract

Es wird ein Drehschlüssel (100) für Mehrkantschrauben oder Muttern vorgeschlagen, dessen Kopfteil stirnseitig eine Aufnahme mit einer die Mehrkantschraube oder Mutter umlaufende Wandung aufweist. In der Wandung (4) der Aufnahme (3) ist vorzugsweise mindestens eine Öffnung (5) vorgesehen, in welcher mindestens ein Klemmteil (9) sitzt. Ein Teil des Klemmteils (9) ragt in die Aufnahme hinein. Im Bereich der Öffnung ist ein Widerlager (7) vorgesehen. Zwischen dem Klemmteil (9) und dem Widerlager (7) ist ein Federelement (13) angeordnet. Beim Einsetzen der Mehrkantschraube wird das Klemmteil (9) gegen die Kraft des Federelements (13) radial nach aussen gegen das Widerlager (7) gedrückt. Bevorzugt ist das Widerlager als Stabilisierungshülse (7) ausgebildet, die dem Kopfteil zusätzliche Stabilität verleiht.

It is proposed a rotary key (100) for polygonal screws or nuts, the headboard has a frontal recording with a polygonal screw or nut circumferential wall. In the wall (4) of the receptacle (3) is preferably at least one opening (5) is provided, in which at least one clamping part (9) sits. A part of the clamping part (9) protrudes into the receptacle. In the area of the opening, an abutment (7) is provided. Between the clamping part (9) and the abutment (7), a spring element (13) is arranged. When inserting the polygonal screw, the clamping part (9) against the force of the spring element (13) is pressed radially outward against the abutment (7). Preferably, the abutment is designed as a stabilization sleeve (7), which gives the headboard additional stability.
