[0016] In summary, the beneficial technical effects of the present invention are:

[0017] 1. A first cover body and a second cover body are used, and a card seat and a card block are added to the two sets of cover bodies. By installing the two sets of cover bodies with the shell, and then engaging the card block with the card seat, and then engaging the plug block with the socket through the expansion and contraction of the spring, the two sets of cover bodies are fixed together, which makes disassembly and assembly convenient;

[0018] 2. Positioning blocks, positioning grooves, sealing rings and sealing strips are used. Positioning grooves and positioning blocks are added to the connecting ring and the cover to achieve the positioning function, so that the cover can be installed more stably, preventing the structure from rotating after installation, ensuring a more stable structure and producing a stable working effect.
