However, the fixing brackets are currently rigidly fixed, which can easily lead to failure of the connection due to excessive internal stress when the pole vibrates. In addition, the existing fixing brackets are fixed and cannot be adjusted to the distance between them and the pole. Since circuit breakers with different loads have different sizes, if a circuit breaker with a small load is replaced with a circuit breaker with a large load, the circuit breaker cannot be installed, thus affecting normal use.
