[0024] The working principle of this utility model is as follows: When using this utility model, the circuit breaker body 1 needs to be assembled with the rear assembly plate 211 via the front mounting plate 216 at the rear end. During the installation of the rear assembly plate 211 and the front mounting plate 216, the adapter slots 214 and mating blocks 215 at the rear and front ends respectively complete the mating process. After the adapter slots 214 and mating blocks 215 are mated, the front mounting plate 216 and the rear assembly plate 211 are positioned using the assembly screws 213. Before installation, the circuit breaker body 1 needs to... The two sets of shock-absorbing inner protective plates 223 are pushed towards the outer walls on both sides by the staff. After the two sets of shock-absorbing inner protective plates 223 are pushed, the distance between the two sets of shock-absorbing inner protective plates 223 increases. After the distance between the shock-absorbing inner protective plates 223 increases, the circuit breaker body 1 can be moved down and installed inside the two sets of shock-absorbing inner protective plates 223. After the circuit breaker body 1 is installed, the two sets of shock-absorbing inner protective plates 223 rebound and squeeze the outer walls on both sides of the circuit breaker body 1 through the damping spring group 222 on the side, so as to carry out the protection and shock absorption work for the outer walls on both sides of the circuit breaker body 1.
