Abstract

L'invention porte sur une clé à rochet permettant des rotations par rochet pour appliquer une série de courses de rotation sur un boulon sans dégagement entre les courses de rotation. La clé à rochet a un corps de clé (10) et une mâchoire à rochet (20). Le corps de clé (10) présente une tête (12) et une fente incurvée (16). La tête (12) a une surface interne. La fente incurvée (16) est formée dans la surface interne de la tête (12). La mâchoire à rochet (20) est montée à coulissement dans la fente incurvée (16) pour appliquer un couple à une tête de boulon pendant une rotation dans la direction vers l'avant ainsi que pour une rotation par rochet pendant une rotation vers l'arrière.
