Abstract

L'invention concerne une clé à double usage comprenant une roue à rochet (4), une détente (5), un ressort (6), un anneau à ressort (7) et un trou circulaire (3) formé sur l'extrémité d'un corps de manche (1). Une clé à fourche est formée sur une extrémité du corps de manche (1) et une clé à rochet est formée sur l'autre extrémité du corps de manche (1). Une fente en demi-lune (9) dans laquelle est montée la détente (5) est formée sur le côté du trou circulaire (3) à proximité du corps de manche (1). Le ressort (6) est emboîté sur une tête d'assemblage à l'extrémité de la détente (5). Une rainure (2) dans laquelle est insérée l'autre extrémité du ressort (6) est formée sur le côté inférieur de la fente en demi-lune (9). Le diamètre d'un côté du trou circulaire (3) est inférieur au diamètre externe de la roue à rochet (4). Une rainure annulaire (8) permettant de monter l'anneau à ressort (7) est formée sur la surface cylindrique interne de l'autre côté du trou circulaire (3) et le diamètre du côté du trou circulaire (3) est supérieur au diamètre externe de la roue à rochet (4). La roue à rochet (4) est placée dans le trou circulaire(3), les rochets de la roue à rochet (4) s'engrènent avec les rochets de la détente (5) et l'anneau à ressort (7) vient en contact de serrage avec la rainure annulaire (8).
