Abstract

L'invention concerne un appareil (100, 200) destiné à interagir avec un composant mécanique tel qu'un élément de fixation. L'appareil comprend une poignée (102, 202) et une tige allongée (104, 204, 304, 404, 504, 604) présentant une extrémité proximale (124, 230) et une extrémité distale opposée (108, 208, 308, 408, 508, 608). L'extrémité distale porte un entraîneur (106, 206, 306, 406, 410, 506, 606) d'outils. L'extrémité proximale est couplée (120, 226) de façon pivotante à un emplacement décalé par rapport à la ligne médiane (115, 210) de la poignée afin de faciliter l'alignement de la tige le long de la poignée dans des positions respectivement allongée et raccourcie, opposées par basculement. En position allongée, l'entraîneur d'outils dépasse d'une première distance au-delà d'une première extrémité (110) de la poignée. En position raccourcie, l'entraîneur d'outils dépasse au-delà d'une deuxième extrémité opposée (112) de la poignée, d'une deuxième distance inférieure à la première distance.
