Hand tool and method for loosening of attachment means, such as a nut, bolt, screw or the like. The hand tool comprises three main parts, a support arm (1), a torque application arm (2) and a socket (3). The socket (3) is intended to grip into the bolt head and mediate a torque from the axle (6) of the hand tool. The support arm (1) forms a holding-up against a supporting base and the torque application arm (2) is used to apply a torque. Both the support arm (1) and the torque application arm (2) have latching devices with respect to the axle (6), which locks in the same direction and implies that a torque applied by the torque application arm (2) is maintained by action of the latching mechanism of the support arm (1). Furthermore, the hand tool is preferably designed with a torque enhancement (8).
L'invention concerne un outil à main et un procédé permettant de desserrer un moyen de fixation, tel qu'un écrou, un boulon, une vis ou équivalent. L'outil à main comprend trois parties principales, un bras support (1), un bras d'application de couple (2) et une douille (3). La douille (3) permet de saisir la tête du boulon et d'induire un couple depuis l'axe (6) de l'outil à main. Le bras support (1) constitue un support contre une base d'appui et le bras d'application de couple (2) permet d'appliquer un couple. Le bras support (1) et le bras d'application de couple (2) ont, par rapport à l'axe (6), des dispositifs de verrouillage qui verrouillent dans le même sens, ce qui signifie qu'un couple appliqué par le bras d'application de couple (2) est maintenu par l'action du mécanisme de verrouillage du bras support (1). En outre, l'outil à main est, de préférence, conçu avec un renforceur de couple (8).
