[0018] The present invention sets a protective mechanism.

When the protective cover moves, it will push the card block and the card slot to move in the direction of approaching each other, and the card block and the card slot are fixed to each other. When the protective cover moves, it pushes the lower push rod to move in the direction of approaching each other. When the lower push rod moves, it pushes the connecting terminal to move downward. When the connecting terminal moves, it pushes the connecting column to move downward. When the lower push rod moves, it pushes the plug terminal to move upward. When the plug terminal moves, it pushes the plug column to move upward. When the connecting column and the plug are connected, the plug terminal and the plug are connected. When the connecting terminal moves to a certain position, the surface of the connecting column and the inner wall of the connecting hole are plugged into each other. When the connecting terminal and the plug-in terminal move, the elastic plate will be squeezed. When the elastic plate is squeezed, the middle part will move in the direction of moving away from each other. When the elastic plate moves, it will push the passive plate to move in the direction of moving away from each other. When the passive plate moves, it will push the sealing rubber plate to move in the direction of moving away from each other and fit into the position where the two protective covers meet and seal them. When the sealing rubber plate moves, it will drive the pulling plate to move in the direction of moving away from each other, effectively protecting the connecting terminal and preventing the connecting terminal from being damaged.

[0019] The present invention provides a fixing mechanism, and the connecting wire passes through the wire insertion hole and is connected to the connecting groove. When the protective cover moves, it drives the right-angle plate to move in the direction of mutual approach, and when the right-angle plate moves, it pushes the pressing rod to move in the direction of mutual approach, and when the pressing rod moves, it pushes the sealing disk to move in the direction of mutual approach, and when the sealing disk moves, it pushes the sliding right-angle rod to move in the direction of mutual approach, and when the sliding right-angle rod moves, it pushes the telescopic rod to retract in the direction of mutual approach, and when the pulling plate moves, it pulls the pulling rod to move in the direction of mutual separation, and when the pulling rod moves, it pulls the passive column to move in the direction of mutual separation. When the passive column moves, it will drive the telescopic rod to move in the direction of approaching each other. When the telescopic rod moves, it will push the sliding right-angle rod to slide on the inner wall of the moving groove in the direction of approaching each other. When the sliding right-angle rod slides, it will push the shrinkage ring to shrink in the direction of approaching each other. When the shrinkage ring moves, it will push the reset elastic rod to move in the direction of approaching each other. When the reset elastic rod moves, it will push the contact rubber ring to move in the direction of approaching each other and fit with the connected surface. It not only fixes the connection to prevent loosening, but also seals the connection between the connecting wire and the wire plug hole to prevent water leakage.

[0020] The present invention provides a reinforcement mechanism. When the sealing disk moves, it drives the passive right-angle plate to move in a direction approaching each other. When the passive right-angle plate moves, it pushes the push plate to move in a direction approaching each other. When the push plate moves, it pushes the driven frame to move in the direction of the protective cover. When the driven frame moves, it pushes the fixed ring to move in the direction of the protective cover. When the contact plate contacts the surface of the protective cover, it squeezes the elastic frame backward. When the elastic frame is squeezed, it pushes the extension ring to slide in a circular shape on the inner wall of the extension groove in a direction away from each other and wraps the surface of the protective cover, thereby effectively reinforcing the surface of the protective cover.
