摘要：
the mechanism comprises a spring-loaded rotary drive member (120), a rotary drive member (40), a pivot coupling (41, 121) coupling the driven member (40) and the drive member (120) in a coupled state and allowing relative clockwise and counterclockwise rotation between driven member (40) and drive member (120) in a decoupled state, and a spring (130) that biases the coupling (41, 121) in its state. coupled and allowing relative axial movement between the driving member (120) and the driven member (40) in the uncoupled state of the coupling (41, 121) against the spring bias (130). the engagement comprises a first crown tooth ring (121) on the drive member (120) and a corresponding second crown tooth ring (41) on the driven member (40) with each crown tooth (41, 121) having at the clockwise and counterclockwise different raised tooth angles, so that the teeth (41, 121) are allowed to overlap in the uncoupled state of the coupling with a different clockwise and counterclockwise resistance. the drive member material (120) may be polybutylene terephthalate (pbt) or polyoxymethylene (pom) and the rotary drive member material (40) may be pbt, pom or polycarbonate (pc).o mecanismo compreende um membro de acionamento giratório acionado por mola (120), um membro acionado giratório (40), um engate (41, 121) giratoriamente acoplar o membro acionado (40) e o membro de acionamento (120) em um estado acoplado e permitindo a rotação relativa no sentido horário e anti-horário entre o membro acionado (40) e o membro de acionamento (120) em um estado desacoplado, e uma mola (130) que polariza o engate (41, 121) em seu estado acoplado e permitindo o movimento axial relativo entre o membro de acionamento (120) e o membro acionado (40) no estado desacoplado do engate (41, 121) contra o viés da mola (130). o engate compreende um primeiro anel de dentes da coroa (121) no membro de acionamento (120) e um segundo anel de dentes da coroa (41) correspondentes no membro acionado (40) com cada d
