The utility model relates to a malfunction prevention device of a breaker, which is used for preventing the malfunction from occurring when the breaker is stricken. The utility model is characterized in that the malfunction prevention device comprises a stop catch (1), a limited piece (2), a support (3), a spring (4), and a rotating shaft (5). The support (3) is fixed on the breaker, and the limited piece (2) is fixed at the proper position of the breaker or the support (3). The stop catch (1) and the spring (4) which are sleeved on the rotating shaft (5) can rotate around the rotating shaft (5). The stop catch (1) is limited at the limited piece (2) under the action of the spring force. Under the condition of the strong impact, the mass center of the stop catch bears the impact force to rotate, and the rotation just causes a trip board rotating by the outside force to back the normal working position, thereby preventing the breaker from being stricken to cause the malfunction. At the moment of the strong imp
