Summary:The utility model provides a tripping mechanism and a circuit breaker, and belongs to the technical field of electrical equipment. The tripping mechanism comprises a tripper, a pulling assembly and a reset piece. The pulling assembly is matched with the release, and when the release acts, the position of the pulling assembly is changed relative to the release so as to control the circuit breaker to release. The reset piece is rotationally connected to one side, close to the moving contact assembly, of the mounting bracket of the release, the reset piece comprises a stress part and an action part, the stress part faces the moving contact assembly, and the action part faces the pulling assembly. In the tripping process of the circuit breaker, the moving contact assembly rotates in the first direction and abuts against the stress part, so that the reset piece rotates in the first direction. When the reset piece rotates in the first direction, the action part abuts against and pushes the pulling assembly so that
