In order to ensure that the bent outgoing busbar 6 and the incoming busbar 5 are in good contact, an adjustable device 3 is arranged between the mounting plate 4 of the outgoing busbar 6 and the circuit breaker 2. The connecting plate 33 can be ejected out from the fine adjustment of the accommodating groove 34 of the fixing seat 31 by operating the fine adjustment mechanism 32, so that the outgoing busbar 6 on the mounting plate 4 is indirectly closely attached to the incoming busbar 5 on the same side, and the outgoing busbar 6 and the incoming busbar 5 are kept in good contact connection.
The fixing seat 31 is of a U-shaped structure, the accommodating groove 34 includes a first sliding cavity 341 and a second sliding cavity 342 which are rectangular and sequentially communicated, the length direction of the first sliding cavity 341 is perpendicular to the moving direction of the connecting plate 33, and the first sliding cavity 341 is located between the second sliding cavity 342 and the circuit breaker 2; the fine adjustment mechanism 32 is disposed in the first sliding chamber 341, and the connection plate 33 is disposed in the second sliding chamber 342.
