[0002] Distribution switches are an important type of electrical equipment in power systems, mainly used to distribute and control the flow of current in power systems, and to achieve access, isolation, load switching, and fault protection for power lines and users. Distribution switches can be divided into many types according to their functions and structures, such as load switches and circuit breakers. Circuit breakers can not only switch on and off normal load currents, but also quickly disconnect circuits in the event of short-circuit faults. They have complete short-circuit and overload protection functions, and some also have ground fault protection capabilities.

[0003] Currently, existing distribution boxes are usually equipped with a protective cover that can be rotated and opened. When the circuit breaker in the distribution box trips, it is convenient to repair it. However, it is difficult to lock the protective cover with existing devices, and the cover is easy to open, which is prone to accidental touch and cause danger.
