Abstract

L'invention concerne un tournevis à cliquet. L'ensemble embrayage (20) est disposé dans la poignée de préhension (10) et est emmanché sur un arbre principal (11) de la poignée de préhension (10). L'ensemble de commande (30) est ensuite disposé mobile sur la poignée de préhension (10), de telle sorte que l'ensemble de commande (30) se déplace vers une première position, une deuxième position ou une troisième position par rapport à la poignée de préhension (10). Lorsque l'ensemble de commande (30) est situé dans la première position, l'ensemble de commande (30) peut commander un ensemble embrayage (20) en vue de permettre à l'arbre principal (11) d'être situé à une première position d'engrenage. Lorsque l'ensemble de commande (30) est situé dans la deuxième position, l'ensemble de commande (30) peut commander l'ensemble embrayage (20) en vue de permettre à l'arbre principal (11) de tourner le long d'une première direction de rotation, de façon à former une deuxième position d'engrenage. Lorsque l'ensemble de commande (30) est situé dans la troisième position, l'ensemble de commande (30) peut commander l'ensemble embrayage (20) en vue de permettre à l'arbre principal (11) de tourner le long d'une deuxième direction rotative, de façon à former une troisième position d'engrenage, ce qui permet d'obtenir un effet bénéfique pour faciliter des opérations.
