Abstract

Une pince de blocage 16 est entraînée par frottement d'une nervure 17 entre les fentes de la douille de blocage 11, entre deux butées 18 et 20. Une fois en position avant la pince de blocage 16 s'ouvre sous l'effet du couple exercé par la butée 21 de la douille de liaison 24. Cette pince de blocage 16 revient en arrière, entraînée par frottement par la douille de blocage 11 et ne se referme qu'une fois arrivée en position arrière.
