Abstract

The utility model relates to circuit breaker detection technical field especially relates to a circuit breaker pusher device. The circuit breaker pusher device includes the base plate, first drive component, swing component, second drive component and first limit component. The drive end of first drive component is connected with base plate drive to drive the base plate to be close to or away from circuit breaker. Swing component is rotatably connected with base plate, and swing component is configured to push the handle of circuit breaker, and the movement track of swing component coincides with the movement track of the handle of circuit breaker. The drive end of second drive component is connected with swing component drive to drive swing component rotation and push the handle of circuit breaker. First limit component is set up on the base plate along the movement track of swing component, and first limit component is configured to limit the rotation range of swing component. The movement track of swing component coincides with the movement track of the handle, and reduces the handle wear and tear risk, and the movable range of the circuit breaker pusher device is controllable, and the stability of pusher operation is improved.
