Abstract

Dans un dispositif d'ancrage, une tête de perçage et un ou des éléments d'expansion sont configurés de manière à se verrouiller en coopération l'un avec l'autre en vue de fournir des mouvements orientés de la tête de perçage par rapport à un axe longitudinal de l'arbre. Des surfaces de contact de coopération entre la tête de perçage et le ou les éléments d'expansion sont configurées de manière à ce que le mouvement longitudinal relatif de la tête de perçage par rapport à l'élément ou aux éléments d'expansion déplace le ou les éléments d'expansion vers l'extérieur de sorte que le ou les éléments d'expansion peuvent fournir un contact de friction avec un forage une fois insérés dans ce dernier.
