In this arrangement, it is ensured that the knocking plate 402 can be reset.

[0051] The implementation principle of a lithium battery charger with a sliding structure in this embodiment is as follows:

[0052] First, when the staff uses the charging pile again, the plug 102 is inserted into the socket body 1011 provided in the charging pile protective shell 101 provided at the charging pile, and power can be supplied by the lithium battery provided in the charging pile;

[0053] When the plug 102 is inserted into the socket body 1011, the protective shell 1022 at the front end of the plug 102 will first contact the outer wall of the socket body 1011, so that under the effect of squeezing, the protective shell 1022 can drive the moving ring 1021 to move horizontally at the moving slide groove 201 and the moving slider 2011 provided on the side wall of the plug 102;

[0054] When the movable ring 1021 moves, it will be able to drive the fixed rod 1023 to move horizontally. At this time, the fixed rod 1023 will be able to squeeze the flip plate 3012 and will be able to rotate with the assistance of the rotating rod 301. When the flip plate 3012 rotates, it will be able to drive the rotating rod 301 to rotate. Therefore, the rotating rod 301 will be able to drive the worm 302 to rotate. Because the worm 302 is meshed with a worm wheel 3021, it can drive the worm wheel 3021 to rotate. When the worm wheel 3021 rotates, it will be able to drive the first rotating rod 3022 and the second rotating rod 3023 to rotate. When the first rotating rod 3022 and the second rotating rod 3023 are The slide groove 3024 and the guide ball as well as the limiting slide groove 303 and the limiting slider 3031 in the second sliding mechanism can move vertically. When the first guide sleeve 3025 and the second guide sleeve 3026 move vertically, the connecting rod 3027 can be driven to move, and when the connecting rod 3027 moves, the positioning plate 3028 can be driven to move. Therefore, the two positioning plates 3028 and the upper and lower side walls of the inner cavity of the charging pile protective shell 101 can be closely fitted, so that the plug 102 and the charging pile protective shell 101 are almost a whole, ensuring that when other people accidentally touch the wiring harness on the plug 102, the plug 102 and the socket body 1011 can be prevented from loosening to a certain extent;

[0055] When disassembly is required, the staff member turns the rotary knob 403 so that the rotary knob 403 can drive the rotating rod 301 to rotate (while gently pulling the plug 301 outward), thereby driving the worm 302 to rotate (thereby enabling the worm 302 to reverse, and when the worm 302 reverses, the worm wheel 3021 can flip over, so that the positioning plate 3028 can be reset with the assistance of the transmission mechanism, the moving mechanism and the second sliding mechanism), until the rotating rod 301 rotates to drive the half gear 401 and the driving gear 4011 to engage, at this time the driving gear 4011 can rotate with the assistance of the rotating shaft 4012, and when the rotating shaft 4012 rotates, it can drive the knocking rod 4013 to rotate, and at this time the knocking rod 4013 can knock on the knocking plate 402, so that the knocking plate 402 can emit a sound, thereby prompting the staff member to pull out the plug 102 with force at this time;

[0056] Because the moving ring 1021 on the plug 102 is limited by the tilting block 2024 in the limiting unit 200 at the initial position, it can be ensured that the moving ring 1021 will not move when there is no squeezing force.
