When the lifting plate 701 descends under the drive of the third driving assembly 702, the switch of the circuit breaker is placed in the space between the two toggle claws 705. At this time, the fourth driving assembly 704 drives the toggle frame 703 to move back and forth along the Y-axis direction, which can drive the two toggle claws 705 to move back and forth, and the switch of the circuit breaker is toggled through the action of the toggle claws 705 to close or open the circuit breaker, so that the circuit breaker can be tested for instantaneous opening and closing actions.

[0017] Specifically, the operation steps of using the circuit breaker automatic test tool provided in this embodiment to test the circuit breaker are as follows: using the conveying component 200 to convey the circuit breaker to be tested and move the circuit breaker to between the testing platform 300 and the positioning component 400; after the circuit breaker is moved between the testing platform 300 and the positioning component 400, the first driving component 403 drives the movable plate 402 to approach the testing platform 300 along the Y-axis direction; at this time, the clamping plate 404 pushes the circuit breaker into the positioning groove 301 and the circuit breaker is clamped between the clamping plate 404 and the pushing plate 601 after entering the positioning groove 301, so as to fix the position of the circuit breaker on the testing platform 300; at the same time, the connecting terminal 500 is connected to the circuit breaker to energize the circuit breaker; after the circuit breaker is fixed on the testing platform 300, the third driving component 702 drives the lifting plate 701 to descend so that the toggle claw 70 5 is close to the switch on the circuit breaker and the switch is placed between the two toggle claws 705. At this time, the fourth driving component 704 drives the toggle frame 703 to move back and forth along the Y-axis direction, and the two toggle claws 705 can respectively toggle the switch to rotate in opposite directions, so that the circuit breaker is repeatedly closed or opened for multiple times, and the circuit breaker can be automatically tested for instantaneous opening and closing actions. After the test is completed, the third driving component 702 drives the lifting plate 701 to reset, and the first driving component 403 drives the movable plate 402 to reset, and then the second driving component 602 is started to drive the push plate 601 to move along the Y-axis direction and push the circuit breaker in the positioning groove 301 that has been tested to the conveying component 200.

At this time, the push plate 601 pushes the circuit breaker in the positioning groove 301 onto the conveying assembly 200 to return the circuit breaker after inspection to the conveying assembly 200. When the second cylinder 604 drives the second piston rod 605 to retract the first cylinder 413, the second piston rod 605 pulls the push plate 601 to make the push plate 601 withdraw from the positioning groove 301, and the push plate 601 is reset.
