[0002] Distribution control equipment is a device used to control and protect electrical equipment in the power distribution system of the power system. They are mainly used to control, monitor and protect electrical equipment in the power system to ensure the safe and stable operation of the power system. Distribution control equipment usually includes various types of switchgear, circuit breakers, contactors, relays, protection devices, metering instruments, etc. These devices can monitor and control the current, voltage, power and other parameters in the power system, and can also perform corresponding protection actions according to the operating status of the system to ensure that the power system can respond correctly in time under various abnormal conditions and ensure the safe and stable operation of the system. Distribution control equipment is widely used in the power distribution system of various places such as industry, commerce, and residence, and is an indispensable and important part of the power system. Through the effective control and protection of distribution control equipment, the reliability, safety and efficiency of the power system can be improved, the normal operation of electrical equipment can be guaranteed, and the failure rate and maintenance cost of the power system can be reduced.

[0003] Circuit breakers are usually fixed with screws, and the fixing method must be firm and reliable to ensure that the circuit breaker will not loosen or shift during use. However, when installing the circuit breaker with screws, the screws are easily loosened due to vibration, which can easily cause the circuit breaker to loosen and affect the normal operation of the circuit breaker.
