The circuit breaker of the first embodiment is described. The mechanism for moving the movable conductor i is configured to be linearly moved by being coupled to an intermediate shaft u of an operation unit (not shown). In contrast, the circuit breaker of the present embodiment is provided with a hollow portion as shown in Fig. 315549 1260663. The movable conductor 1 is formed with a female thread on the inner peripheral surface of the main circuit side portion of the insulating rod 13: The male threaded threaded rod 14 is fixedly formed with a hollow portion of the female thread screw. The snail rod 14 is embedded in the movable conductor. According to the circuit breaker configured as described above, when the screw rod 14 of the insulating rod 13 is rotated: the insulating rod 13, the fixing can be fixed due to the inner peripheral surface of the hollow portion formed in the eight of the bolt rods 14. The threaded two threads of the female thread move linearly with the moving conductor 1 formed on the movable conductor 1. σ, when the bolt rod 14 rotates, the operation can save Φ„h i J, the movement of the cloud intermediate shaft 11 .乍 间 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , (:) indicates the state in which the circuit is connected to the ground when the circuit is connected.

This embodiment can save the intermediate car from being simplified. The 'axis' can move more [industry availability] 315549 14 1260663 According to the present invention, assembly and adjustment work is easy, and miniaturization is achieved. The three-point disconnection n (the circuit breaker in which the circuit is connected, the grounded state, and the open circuit) is effective.
