   Es zeigt:       Fig.    1 eine Vorderansicht, und       Fig.    2. eine     Seitenansicht    des Schlüssels,  während       Fig.    3. die einzelnen auswechselbaren  Stifte, und       Fig.    4 den Schlüssel samt     mit    ihm an  ziehbaren     bezw.        losschraubbaren        Schraub-          stücken    darstellt.  



  Der in     Fig.    1 und 2     dargestellte    Schlüs  sel besitzt einen Griff H mit zwei halbrun  den Scheiben     m    und     n.    Die Scheibe     m    ist  mit dem Griff H fest verbunden, während  die Scheibe     n    um den im     Kopfstück    des  Griffes H gelagerten, senkrecht zur     Scheibe          rt    stehenden Bolzen     S    drehbar ist und durch  eine halbrunde Ausfräsung     t    an der Scheibe       in    geführt wird.

   Die halbrunden Aussparun  gen im Zentrum der Scheiben m und     n    haben  den Zweck, eventuell aus dem     Schraubstück     hervorragende     Bolzenenden        etc.    in sich auf-    zunehmen.     Die    Scheiben     in    und     n        tragen    an  ihrer     Peripherie    die     Rundstiften        a,    näher dem       Zentrum    zu dagegen die     schneidenförmigen     Stifte b.

  Keys for screwdrivers, especially those on bicycles. The present invention is a key for tightening BEZW. Loosen screw pieces, especially on bicycles. On the accompanying drawing an embodiment of the subject of the invention is shown.

   It shows: Fig. 1 is a front view, and Fig. 2 is a side view of the key, while Fig. 3, the individual interchangeable pins, and Fig. 4, the key and pullable respectively with it. represents unscrewable screw pieces.



  The key shown in Fig. 1 and 2 sel has a handle H with two semicircular discs m and n. The disc m is firmly connected to the handle H, while the disc n is mounted in the head of the handle H, perpendicular to the disc rt standing bolt S is rotatable and is guided through a semicircular recess t on the disc.

   The semicircular cutouts in the center of the washers m and n have the purpose of accommodating bolt ends etc. that may protrude from the screw. The disks in and n have the round pins a on their periphery, but closer to the center they have the blade-shaped pins b.

   These pins are exchangeable and are attached to the washers 7n and n by means of nuts.



  The key is now in the manner of the screw c BEZW. d (see Fig. 4) is laid out that the round pins a respectively into the holes k of the screw piece c. the cut-shaped: pins b engage in .die slots g of the screw piece d, so that now the screw piece c respectively. d can be easily loosened or tightened.
