Grounding contact knife control mechanism of isolation type vacuum circuit breaker

The invention is applicable to the technical field of grounding contact knives of vacuum circuit breakers, and provides a grounding contact knife control mechanism of an isolation type vacuum circuit breaker, which comprises a mounting plate, a circuit breaker body and a knife switch mechanism, and is characterized in that the rear side surface of the mounting plate is fixedly connected with two mounting blocks, and a rotating shaft is transversely and rotatably connected between the two mounting blocks; the knife switch mechanism is arranged on the surface of the rotating shaft. According to the grounding contact knife control mechanism of the isolation type vacuum circuit breaker, the knife switch mechanism is arranged, the grounding contact knife control mechanism of the vacuum circuit breaker drives the contact piece to move through the pull rod, the pull rod is perpendicular to the contact piece, and when the grounding contact knife control mechanism does not need to be connected with the output end of t
