[0058] In addition, as a preferred embodiment, Figures 1 to 3 As shown, the lock mechanism 3 of this embodiment includes a card joint 31 provided on the first shell 1, and a card slot 32 provided on the second shell 2. The card joint 31 can be carded in the card slot 32, and the first shell 1 can be fixed to the second shell 2 through the cooperation of the card joint 31 and the card slot 32. The setting of the card joint 31 and the card slot 32 facilitates the convenient opening of the lock mechanism 3, facilitates the flipping operation during maintenance by workers, and facilitates the design implementation.

[0059] As a preferred embodiment, Figure 6 and Figure 7 As shown, the clamping joint 31 in this embodiment is provided with an elastic clamping portion, and the clamping slot 32 is provided with a receiving slot for accommodating the elastic clamping portion. When the clamping joint 31 is clamped in the clamping slot 32, the elastic clamping portion can be clamped in the receiving slot, and the elastic clamping portion can be compressed during the process of the clamping joint 31 being clamped in the clamping slot 32.
