[0007] The circular charging port cover is placed inside the limiting ring, and the lower positioning rod is turned to cooperate with the limiting ring to limit and fix the circular charging port cover. The rectangular charging port cover can also be placed inside the limiting frame, and the upper positioning rod is turned to cooperate with the limiting frame to limit and fix the rectangular charging port cover. The charging port cover is pushed out of the device by pushing the top plate through the electric push rod.

[0008] Preferably, positioning pieces are fixedly connected to both sides of the bottom of the base, and bolt holes are provided inside the positioning pieces.

[0009] The device can be installed on the external structure for use by connecting the positioning piece with the external structure and then screwing the external fixing bolts between the positioning piece and the external structure and passing through the bolt holes.

[0010] Preferably, heat sinks are movably mounted on surfaces at both ends of the base, and heat sinks are provided inside the heat sinks.

[0011] By setting the heat dissipation groove inside the heat dissipation plate, the heat generated when the electric push rod is running can be discharged from the device through the heat dissipation groove.

[0012] Preferably, a fixing piece is fixedly connected to the outer side wall of the limiting frame, and the upper positioning rod and the lower positioning rod both overlap with the fixing piece.

[0013] The fixing piece can limit the movement direction of the upper positioning rod and the lower positioning rod, thereby improving the stability of the movement of the upper positioning rod and the lower positioning rod.

[0014] Preferably, a buffer block is fixedly connected to the top of the top plate, and the buffer block is made of silicone rubber.
