Abstract

L'invention porte sur une pince mécanique ou pince de tenue qui comprend un ensemble mâchoire que l'on pousse de sorte qu'il vienne en contact avec un tuyau par l'intermédiaire d'un suiveur de came qui vient en contact avec la surface de came sur la circonférence interne d'une couronne, le suiveur de came se présentant sous la forme d'une série de roues agencées comme un palier de circulation. Selon une forme préférée, les roues sont des appuis cylindriques et l'ensemble mâchoire est monté de façon à avancer par coulissement vers le tuyau contre lequel il doit venir en contact. En variante, le suiveur de came comprend un guide d'indexage qui maintient les appuis cylindriques dans un alignement correct.
