1. Unidirektionaler Ratschenschlüssel, der folgendes umfaßt:
einen Schlüsselkörper (10), mit einem in einem Ende definierten gezahnten Hohlraum (12), wobei an einem Innenumfang des gezahnten Hohlraums (12) mehrere Zähne (13) ausgebildet sind und jeder Zahn (13) eine geneigte Fläche (131) und eine aufrechte Fläche (133) aufweist, wobei die geneigten Flächen (131) alle in der gleichen Richtung angeordnet sind;
eine Ratsche (20), die unidirektional und drehbar im gezahnten Hohlraum (12) des Schlüsselkörpers (10) befestigt ist und
einen in der Ratsche (20) definierten und zum Eingriff mit einer Mutter oder einem ähnlichen Verbindungsteil ausgeführten Einsatz (21);
eine in Querrichtung um einen Außenumfang der Ratsche (20) herum definierte ringförmige Aussparung (22); und
mindestens zwei in gleichmäßigen Abständen im Außenumfang der Ratsche (20) definierte Blockaussparungen (23) aufweist;
einen Expansionsring (30), der in der ringförmigen Aussparung (22) angebracht ist und dessen Innendurchmesser etwas größer ist als der Außendurchmesser eines Teils in der ringförmigen Aussparung (22) der Ratsche (20); und
mindestens zwei Klemmblöcke (40), die jeweils in den mindestens zwei Blockaussparungen (23) aufgenommen und am. Expansionsring (30) angebracht sind, wobei jeder Klemmblock (40) eine nach außen weisende gezahnte Fläche zum Eingriff mit dem gezahnten Hohlraum (12) des Schlüssels (20) aufweist;
wobei der Expansionsring (30) eine elastische Rückstellkraft an den mindestens zwei Klemmblöcken (40) bereitstellt, um zu bewirken, daß die Klemmblöcke (40) mit dem gezahnten Hohlraum (12) in Kontakt bleiben.1. One-way ratchet wrench, which includes:
a key body ( 10 ) with a toothed cavity ( 12 ) defined in one end, a plurality of teeth ( 13 ) being formed on an inner circumference of the toothed cavity ( 12 ) and each tooth ( 13 ) having an inclined surface ( 131 ) and an upright one Surface ( 133 ), the inclined surfaces ( 131 ) are all arranged in the same direction;
a ratchet ( 20 ) which is unidirectionally and rotatably mounted in the toothed cavity ( 12 ) of the key body ( 10 ) and
an insert ( 21 ) defined in the ratchet ( 20 ) and configured to engage a nut or similar connector;
an annular recess ( 22 ) defined transversely around an outer periphery of the ratchet ( 20 ); and
has at least two block recesses ( 23 ) defined at regular intervals in the outer circumference of the ratchet ( 20 );
an expansion ring ( 30 ) mounted in the annular recess ( 22 ) and the inside diameter of which is slightly larger than the outside diameter of a part in the annular recess ( 22 ) of the ratchet ( 20 ); and
at least two clamping blocks ( 40 ), each received in the at least two block recesses ( 23 ) and attached to the expansion ring ( 30 ), each clamping block ( 40 ) having an outwardly facing toothed surface for engagement with the toothed cavity ( 12 ) of the Key ( 20 );
wherein the expansion ring ( 30 ) provides an elastic restoring force on the at least two clamping blocks ( 40 ) to cause the clamping blocks ( 40 ) to remain in contact with the toothed cavity ( 12 ). 2. Unidirektionaler Ratschenschlüssel nach Anspruch 1, bei dem der Einsatz (21) als ein regelmäßiges Vieleck definiert ist.2. A unidirectional ratchet wrench according to claim 1, wherein the insert ( 21 ) is defined as a regular polygon. 3.
