Abstract

La présente invention divulgue un mécanisme de mouvement, un dispositif de chauffage et une machine de thermorétraction. Le mécanisme de mouvement comprend : une première tige de liaison (21) reliée à un mécanisme d'entraînement pour se déplacer avec cette dernière ; une seconde tige de liaison (22) qui est reliée de manière pivotante à la première tige de liaison (21) pour tourner autour d'un axe de pivotement par rapport à la première tige de liaison (21) ; une broche de guidage (23) fixée sur la seconde tige de liaison (22) ; et un rail à fente (24) formé avec une fente de guidage (240) qui est mise en correspondance de manière coulissante avec la broche de guidage (23) pour guider le déplacement de la broche de guidage (23) le long de cette dernière. Lorsque la première tige de liaison (21) est entraînée à se déplacer, la seconde tige de liaison (22) entraîne une unité d'actionnement reliée à cette dernière pour commuter entre différentes orientations, de telle sorte que l'unité d'actionnement entraînée présente différentes orientations. Dans la présente invention, le mécanisme de mouvement peut entraîner le dispositif de chauffage à se déplacer entre différentes stations et commuter entre différentes orientations, de telle sorte que le dispositif de chauffage peut non seulement chauffer le tube thermorétractable sur l'extrémité du câble, mais également chauffer le tube thermorétractable entre deux extrémités du câble. Par conséquent, la présente invention peut augmenter la plage d'application et l'efficacité de fonctionnement de la machine de thermorétraction.
