Abstract

Afin de fournir un dispositif électrique présentant une grande facilité d'utilisation par rapport aux dispositifs antérieurs, un outil électrique 1 selon l'invention comporte un boîtier 2, une partie de poignée 3 disposée de manière rotative sur le boîtier 2 par l'intermédiaire d'un axe de rotation 10 et un crochet 5 (outil de suspension) disposé au niveau d'une partie d'extrémité de la partie de poignée 3. En position rétractée, le crochet 5 entoure un côté d'extrémité de la partie de poignée 3 dans une direction autour d'un axe de la partie de poignée 3. Une section de coin d'un bloc-batterie 30 coopère avec le crochet 5 de manière à limiter la rotation du crochet 5 de la position rétractée vers une position d'utilisation.
