The inspection door 201 is closed, the reel 204 is rotatably connected to the inner wall of the charging pile 1, and the knob 205 is arranged on the outside of the charging pile 1, so that the knob 205 can be easily rotated, thereby driving the reel 204 to rotate, and an embedded frame 207 is fixedly connected to the inspection door 201, and the embedded frame 207 matches the electricity meter 3, so that the electricity meter 3 can be embedded in the embedded frame 207. One end of the electricity meter 3 is slidably connected to a movable frame 208, and a first spring 209 is provided between the movable frame 208 and the inner wall of the electricity meter 3, which can reset the movable frame 208. The movable frame 208 is fixedly connected to the end away from the first spring 209. There is an inclined card block 210, and two telescopic rods 211 are fixedly connected to the inner wall of one side of the embedded frame 207. The ends of the two telescopic rods 211 are fixedly connected to push plates 212.
