Abstract

L'invention concerne un dispositif de serrage à axe double dans lequel en attachant une seule vis, un premier axe est tout d'abord serré, puis ladite vis est attachée, serrant ainsi un second axe, et qui permet une meilleure précision de positionnement dans une opération de serrage ainsi qu'une amélioration de l'opérabilité. Le dispositif de l'invention comporte un châssis (10), un corps de serrage (20) maintenu dans le châssis, et un boulon d'attache (33) assemblé sur le châssis. En attachant le boulon d'attache (33), l'extrémité avant de ce dernier pousse le corps de serrage (20), et le premier axe (31) est tout d'abord coincé et maintenu entre une première surface de contact d'axe agencée côté châssis et une première surface de contact d'axe agencée côté corps de serrage. Puis, un second axe (32) se trouvant passé au travers d'un second trou d'insertion du corps de serrage, et présentant une structure se déformant facilement de façon élastique à l'aide d'une fente (23) aménagée côté second trou d'insertion, se trouve ainsi maintenu.
