L'élément d'embiellage peut entraîner chaque bloc (4) de freinage en rotation, de telle sorte que le bloc (4) de freinage porte contre la partie de frein sur le loquet (5) de serrure ou soit séparé de celle-ci. Les parties de frein sont disposées symétriquement sur les deux extrémités du loquet (5) de serrure dans le dispositif de serrure. Lorsque le loquet (5) de serrure est verrouillé, les parties de frein disposées sur les deux extrémités du loquet (5) de serrure sont en contact avec un arbre principal (6). Le loquet (5) de serrure est soumis à des contraintes uniformes, et n'est pas distordu et déformé, de sorte que la durée de vie en service du dispositif de serrure est prolongée. Le dispositif de serrure peut être utilisé dans différents environnements de contraintes, de sorte que le domaine d'application du dispositif de serrure est agrandi. Le loquet (5) de serrure contraint sur deux côtés peut résister à un test d'impact dynamique important.
