Abstract

Le carottier comprend, dans un train de tubes extérieurs, un tube intérieur à tête d'accrochage avec un crochet tronconique supérieur et cône de déverrouillage, tube intérieur verrouillable en position de carottage par un verrou à pattes Le carottier a une pièce de descente à cloche inférieure fendue reliée à une tige s'étendant vers le haut, une tête supérieure d'accrochage à crochet tronconique, solidaire d'un tube intermédiaire s'étendant vers le bas, un ressort hélicoïdal logé entre celui-ci et la tige et prenant appui sur des embases du tube et de la tige, et une bague vissée sur le tube et entourant la cloche en position inférieure. La pièce de descente coopère avec le porte-verrou du tube intérieur pour déplacer ce dernier.
