Description

Schraubenschlüssel mit Spannhebel. Die Erfindung betrifft einen Schraubenschlüssel mit Spannhebel, 'wobei als Verbindung der Schiebebacke mit dem Hebel eine Zugfeder dient, die den Schlüssel nach Gebrauch wieder öffnet.Wrench with clamping lever. The invention relates to a wrench with clamping lever, 'with a tension spring connecting the sliding jaw to the lever which opens the key again after use.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung veranschaulicht. ix zeigt die Zugfeder, welche wie bei 7 ersichtlich an der Schiebebacke 5 befestigt ist und anderseits bei =q. am Spannhebel 8 angebracht, diesen nach vorn und aufwärts sowie gleichzeitig die Schiebebacke abwärts zieht.An exemplary embodiment of the invention is illustrated in the drawing. ix shows the tension spring which, as can be seen at 7, is attached to the sliding jaw 5 is and on the other hand at = q. attached to the clamping lever 8, this forward and upward as well as pulling the sliding jaw downwards at the same time.

Gegenüber bekannten Werkzeugen dieser Art besteht das Wesen der vorliegenden Erfindung darin, daß die bei 15 freiruhend auf dem Spannhebel angeordnete Schiebebacke 5 mit diesem Hebel durch die Schraubenzugfeder so verbunden ist, daß die Feder den Schlüssel nicht nur nach jedem Gebrauch wieder öffnet, sondern gleichzeitig auch die Hebelachse 12 in dem eingestellten Nutenlager q. festhält, so daß der Schlüssel in keiner Lage seine Greifweite ändern kann.Compared to known tools of this type, there is the essence of the present Invention is that the sliding jaw arranged free-standing at 15 on the clamping lever 5 is connected to this lever by the helical tension spring that the spring the The key not only opens again after each use, but also at the same time the lever axis 12 in the set grooved bearing q. holds tight so that the key cannot change its reach in any position.
