Abstract

An anti-jamming device for an energy storage handle of a universal circuit breaker comprises a circuit breaker body (1), and an operating mechanism (2) mounted on one side of the circuit breaker body (1). The energy storage handle (3) is mounted on the outside wall of one side of the operating mechanism (2). The energy storage handle (3) is rotated to manually store energy for the operating mechanism (2). The operating mechanism (2) comprises a V-shaped rotating shaft (4), wherein one end of the V-shaped rotating shaft (4) extends out of one sidewall of the operating mechanism (2), and the other end of the V-shaped rotating shaft (4) is sleeved with a ratchet (5) which is in linkage with the energy storage handle (3). A latch (6) which is in linkage with the ratchet (5) is arranged on one side, facing the ratchet (5), of the energy storage handle (3). The energy storage handle (3) is rotated to drive the ratchet (5) to rotate through the latch (6). An anti-jamming structure which prevents the latch (6) and the ratchet (5) from being jammed is arranged between the latch (6) and the ratchet (5). The anti-jamming structure comprises an anti-jamming plate (8). The anti-jamming plate (8) is configured to separate the latch (6) from the ratchet (5) when the energy storage handle (3) is in an initial state.
