For example, three anti-theft screws 212 are set on both sides and the bottom where the back plate 11 and the middle frame 21 overlap. The back plate 11 is designed with a snap 211 and an anti-theft screw 212 fixing method, which not only meets the sealing requirements but also simplifies the assembly. After the snap 211 is tightened, the anti-theft screws 212 are driven, and no additional manual lifting of the charger body 2 is required.
