When the circuit breaker needs to be disassembled, the claw 401 is pulled so that the elastic card block on the claw 401 is located inside the positioning slot 6, and the guide rail is separated from the mounting slot 2. By setting up the positioning slot 6, when the elastic card block on the claw 401 is located inside the positioning slot 6, the mounting block 404 will no longer contact the guide rail, which can prevent the guide rail from being damaged when it detaches from the mounting slot 2.
[0017] A stopper 405 is fixedly connected to one side of the mounting block 404 , and the stopper 405 is located inside the slide groove 3 ; by setting up the stopper 405 , the mounting block 404 can be prevented from falling off from the slot 8 .
