Abstract

Ce système de maintien d'outil comprend une partie de mécanisme de verrouillage (600) destiné à verrouiller un outil maintenu par une partie de maintien d'outil (51). La partie de mécanisme de verrouillage (600) présente : une partie de mise en prise (531) mobile entre une première position (Pa) dans laquelle la partie de mise en prise (531) vient en prise avec l'outil et verrouille l'outil, et une deuxième position dans laquelle la partie de mise en prise (531) est rétractée à partir de la première position (Pa) et déverrouille l'outil ; un élément de sollicitation (541) mobile entre une troisième position (Pc) dans laquelle l'élément de sollicitation (541) sollicite la partie de mise en prise (531) en direction de la première position (Pa), et une quatrième position dans laquelle l'élément de sollicitation (541) est rétracté à partir de la troisième position (Pc) et libère la sollicitation par rapport à la partie de mise en prise (531) ; et un élément de restriction (551) mobile entre une cinquième position (Pe) dans laquelle l'élément de restriction (551) vient en contact avec la partie de mise en prise (531), limite le mouvement de la partie de mise en prise (531) à partir de la première position (Pa) en direction de la deuxième position et maintient la partie de mise en prise (531) dans la première position (Pa), et une sixième position dans laquelle l'élément de restriction (551) est rétractée à partir de la cinquième position (Pe) et permet le mouvement de la partie de mise en prise (531) entre la première position (Pa) et la deuxième position.
