Abstract

L'invention vise à mettre au point un raccord coaxial, abouchable à la manière d'un raccord rapide, de calibre unitaire, et pouvant s'utiliser pour des outils rotatifs ou oscillants, de préférence comme matériel portatif pour découper de la viande rôtie (grill gyros-döner). A cet effet, il est prévu, pour fixer les parties de raccordement assemblées, au moins un aimant permanent (13, 23) sur la partie saillante (11) ou dans la base de l'évidement cylindrique creux (21), qui coopère avec la pièce antagoniste, de sorte que les deux parties soient attirées l'une contre l'autre, sous l'effet de l'interaction magnétique. Dans une version plus perfectionnée, une des parties de raccordement se présente sous forme de partie d'entraînement (40) et l'autre, sous forme de tête d'outil (50). Un arbre primaire accouplé de manière détachable transmet le mouvement rotatif ou oscillant à l'outil et il est prévu comme moyen d'entraînement, un moteur (42) et comme outil, une lame rotative (64).
