The second abutment plate extends out, and the second abutment plate slides inside the base 1. The two second abutment plates can simultaneously cooperate with the two rotating rods 46 on the same side of the base 1 to move. When the chain rod 44 is driven by the hydraulic cylinder 41 to rotate during the opening stroke, the end of the chain rod 44 close to the abutment frame 45 will rotate downward. At this time, the chain rod 44 will push the abutment frame 45 downward, and the abutment frame 45 will move downward.

At this time, the output end surface of the hydraulic cylinder 41 will push the chain rod 44 to rotate and enter the second state. In the second state, when the chain rod 44 rotates through the limit frame 43, its end close to the abutment frame 45 will rotate downward. At this time, the abutment frame 45 will be pushed and move downward. At this time, the top of the abutment frame 45 will pull the end of the rotating rod 46 located in the base 1 downward through the protrusion 451. At this time, the rotating rod 46 will rotate through the connecting frame 2, and the movement trajectory of the end of the shielding plate 47 close to the base 1 is as shown in Figure 5 As shown, the shutter 47 will not collide with the top of the base 1 when it is opened. At this time, the shutter 47 will be opened, and the hydraulic cylinder 41 will drive the charging pile body 3 to move outside the base 1, so as to facilitate use. When the hydraulic cylinder 41 descends and contracts, as the output end of the hydraulic cylinder 41 descends, the chain rod 44 still abuts against the output end of the hydraulic cylinder 41.
