Abstract

L'invention porte sur un outil à multiples embouts qui comprend un boîtier ayant un mandrin à embout avec une ouverture de réception d'embout. Un élément de cadre principal sensiblement rigide définit une pluralité de canaux longitudinaux et est disposé à l'intérieur du boîtier, de telle sorte que chacun de la pluralité de canaux longitudinaux est globalement aligné selon l'axe longitudinal de l'outil à multiples embouts. Une pluralité de mécanismes d'actionnement à ressort sont montés dans une relation de retenue rigide à l'intérieur d'un canal de l'élément de cadre. Chaque mécanisme d'actionnement à ressort a un élément de support mobile entre une position vers l'arrière et une position vers l'avant, et un élément de déclenchement mobile entre une position de repos, une position de déclenchement vers l'avant et une position de déclenchement vers l'arrière. L'élément de support est déplacé à sa position vers l'arrière par déplacement de l'élément de déclenchement à sa position de déclenchement vers l'arrière et l'élément de support est déplacé à sa position vers l'avant par déplacement de l'élément de déclenchement à sa position de déclenchement vers l'avant. Des ensembles embouts ayant un embout d'outil sont montés de manière fonctionnelle à l'intérieur du boîtier pour un déplacement, par le mécanisme d'actionnement, entre une configuration rétractée et une configuration d'utilisation étendue vers l'avant correspondante. Chaque ensemble embout est relié de manière fonctionnelle à l'élément de support sur un mécanisme à ressort correspondant pour un déplacement coopératif avec celui-ci.
