Abstract

L'invention concerne une structure de bras d'arbre à tête sphérique et une structure à tête sphérique comportant la structure de bras d'arbre à tête sphérique. La structure de bras d'arbre à tête sphérique (1) comprend un premier bras d'arbre (2), un second bras d'arbre (3) et un mécanisme de verrouillage (10) apte à verrouiller le premier bras d'arbre (2) et le second bras d'arbre (3). Le mécanisme de verrouillage (10) comprend : un élément coulissant, un élément d'entraînement et un élément de serrage (151) disposé sur le second bras d'arbre (3). L'élément d'entraînement amène l'élément coulissant à se déplacer d'une première position à une seconde position de façon à permettre à l'élément de serrage (151) de fixer ou de libérer le premier bras d'arbre (2), ce qui permet de verrouiller et de déverrouiller le premier bras d'arbre (2) et le second bras d'arbre (3). La structure de bras d'arbre à tête sphérique de la présente invention permet le déplacement de l'élément coulissant, par l'intermédiaire de l'élément d'entraînement, de la première position à la seconde position, afin de permettre à l'élément de serrage de fixer ou de libérer le premier bras d'arbre, ce qui permet de verrouiller ou de déverrouiller le premier bras d'arbre et le second bras d'arbre.
