[0030] Working principle: When the manual circuit breaker and the circuit breaker are used at the same time, the cylinder 31 is started. Under the action of the cylinder 31, the cylinder 31 drives the telescopic rod 33 to move through the connecting plate 1 32. Under the action of the telescopic rod 33, the telescopic rod 33 squeezes the connecting plate 2 34.
