Abstract:
A tripping mechanism of a circuit breaker, and a circuit breaker. The tripping mechanism comprises a jump pin (17), a re-buckle (18) and a lock latch (20), which are rotatably arranged, wherein the re-buckle (18) is of a labor-saving lever structure and comprises a first lever arm (181) and a second lever arm (182); a first lap joint portion (1703) is arranged on the jump pin (17), a first press-fitting portion (1801) is correspondingly provided on the first lever arm (181); and a second lap joint portion (1803) is provided on the second lever arm (182), and a second press-fitting portion (2001) is correspondingly provided on the lock latch (20). The relative positions of the jump pin (17), the re-buckle (18) and the lock latch (20) are configured in such a way that, by means of relative rotation between each other, the first press-fitting portion (1801) is press-fitted to the first lap joint portion (1703) while the second press-fitting portion (2001) is press-fitted to the second lap joint portion (1803), thus the rotation of the jump pin (17) is limited, a first rotating force arm (L1) of the first press-fitting portion (1801) being smaller than a second rotating force arm (L2) of the second lap joint portion (1803).
