Abstract

Ein Ratschenschlüssel mit in einem maulförmigen Schlüsselkopf (2) durch ein Klinkengesperre in nur einer Richtung drehbaren, ein Maul (4) aufweisenden Nuß (3) besitzt ein Paar bewegbarer Eingriffsglieder, die in zwei einen Abstand aufweisende und dadurch die Maullücke überbrückende Bereiche eines an der Nuß angeordneten Drehkranzes eingreifen und die beim Bewegen ein Drehen der Nuß entgegen der Sperrwirkung des Gesperres bewirken. A ratchet wrench with a jaw-shaped key head (2) can be rotated in one direction only by a ratchet mechanism The nut (3) has a pair of movable jaws (4) Engagement members that are spaced apart in two and thereby areas of the gap bridging one on the nut arranged turntable and engage when moving Rotate the nut against the locking effect of the locking mechanism.

Die Eingriffsglieder und der Drehkranz sind vorzugsweise als Klinken/Klinkenverzahnung oder als Zahnräder ausgebildet. The engagement members and the slewing ring are preferably as Pawls / pawl teeth or designed as gear wheels.

Dies erleichtert das zum Abziehen des Ratschenschlüssel von Verschraubungen, deren Gewindeenden nicht frei sind, erforderli­ che Verdrehen der Nuß, bis das Maul der Nuß (4) und das Maul des Schlüsselkopfes (6) übereinander stehen und das Werkzeug radial abgezogen werden kann. This makes it easier to remove the ratchet wrench from Screw connections, the thread ends of which are not free, required che twisting the nut until the mouth of the nut (4) and the mouth of the Key head (6) are one above the other and the tool is radial can be deducted.
