  Schnellverstellbarer Schlüssel für Röhren, Stangen usw.         Gegenstand,der    Erfindung ist ein Schlüs  sel zum Anziehen von Röhren,     Stangen    und       dergleichen,        welcher        eine    rasche     Verstellung     der Backen auf     verschiedene    Abstände er  möglicht.  



  Der     Nachteil    bisheriger     Schlüssel        ist,    dass       beim        Verändern.    des     Durchmessers    der Röhre  oder der Stange     es    notwendig     ist,    den Ab  stand der Backen     umständlich,    z. B.     @dhrch     Lösender     Verbindungsschraube,    zu verändern.  



  Abgesehen vom Zeitverlust,     besteht    noch  die     Möglichkeit        des.        Verlorengehens    der Ver  bindungsschraube oder Mutter.  



  In der     Zeichnung    ist ein     Ausführungms-          beiepiel        -des    Erfindungsgegenstandes darge  stellt.  



  Der     Schlüssel        besitzt    zwei Arme     L    und 2.  Der Arm 1 ist in     seinem    obern Teil     abge-          kröpft    und     bildet    eine Backe. Dieser Arm ist  massiv. Der Arm 2 ist     hohl,    und zwar     in:    der  Weise, dass er im Querschnitt     U-Form    be  sitzt.

   Sein oberer Teil bildet     dieuntere        Backe.     Die Backen     .der    beiden Arme     sind    mit einer  Reihe von     parallelen    Zähnen versehen., wo  durch die Möglichkeit des     Abrutechens    der  Backen beim     Fassen    einer     Rdhre        ausgeEchlos-          sen    ist.  



  Der Arm     2@        besitzt        eine        einzige    Öffnung  7,     der    Arm 1 eine     Reihe.    von Öffnungen, die  zur Änderung des,     Abstandes    der beiden     Bak-          ken    voneinander dienen. Durch ,die     Üfffnun-          gen        des    Armes 1 und 2 geht ein Zapfen 3  hindurch,     mittels        welches        b    erde Arme ,gelen  kig miteinander     verbunden    sind.  



  An seinem einen Ende     ist,der    Zapfen 3  mittels     einer    Schraube 5 oder einer Nute mit    einem freien Ende einer flachen Feder 4 fest  verbunden. Das zweite Ende 6 ,dieser     Feder     ist am Arm 2     befestigt.    Durch die Wirkung  der Feder ist     ,der    Zapfen in den sieh     decken     den     Öffnungen    der beidem     Arme    gesichert;  die     Lösung        .des        Zapfens        geschieht    durch  Kraftwirkung entgegen der     Feder.     



  Eine     derartige    Anordnung ermöglicht eine  rasche und     verlässrliche        Änderung        des    Ab  standes der Backen gemäss     des    Durchmessers       .der    Röhre, Stange und     dergleichen,    wobei die  Möglichkeit des     Verlorengehens    des     Verbin-          dun.gszapfens-    ausgeschlossen ist.



  Quickly adjustable key for tubes, rods, etc. The subject of the invention is a key for tightening tubes, rods and the like, which allows the jaws to be quickly adjusted to different distances.



  The disadvantage of previous keys is that when changing. the diameter of the tube or the rod it is necessary to stand the jaws awkward, z. B. @dhrch loosening connecting screw to change.



  Apart from the loss of time, there is still the possibility of the connecting screw or nut being lost.



  In the drawing, an exemplary embodiment of the subject matter of the invention is shown.



  The key has two arms L and 2. Arm 1 is bent in its upper part and forms a cheek. This arm is massive. The arm 2 is hollow, namely in: the way that it sits in a U-shape be in cross section.

   Its upper part forms the lower jaw. The jaws of the two arms are provided with a series of parallel teeth, which ruled out the possibility of the jaws slipping off when grasping a wheel.



  The arm 2 @ has a single opening 7, the arm 1 a row. of openings that serve to change the distance between the two jaws. A pin 3 passes through the openings of the arms 1 and 2, by means of which ground arms are articulated with one another.



  At one end, the pin 3 is firmly connected to a free end of a flat spring 4 by means of a screw 5 or a groove. The second end 6 of this spring is attached to the arm 2. By the action of the spring, the pin is secured in the openings of both arms; the solution of the pin is done by force acting against the spring.



  Such an arrangement enables a quick and reliable change in the distance between the jaws according to the diameter of the tube, rod and the like, with the possibility of the connecting pin getting lost is excluded.
