[0025] Furthermore, the slide groove 2 and the slider 3 are both in two groups, the slider 3 is adapted to the slider 3, and the needle 4 is slidably connected to the inner side of the connecting sleeve 1. Its function is that when the electronic product is charged, the charger of the electronic product is combined with the needle 4, thereby squeezing the needle 4, so that the needle 4 slides on the inner side of the connecting sleeve 1.

[0026] Furthermore, the connecting rod 5 is in a rod-like shape, and the connecting rod 5 is fixedly connected between the needle 4 and the connecting plate 6. The connecting plate 6 is in a plate-like shape, and the slide groove 8 is a cylindrical groove. The connecting rod 5 and the connecting plate 6 are both slidably connected to the inner side of the slide groove 8. Its function is to slide the slider 3 on the inner side of the slide groove 2 so that the two groups of sliders 3 limit the position of the needle 4 in the connecting sleeve 1 to prevent the position of the needle 4 from loosening, so that the needle 4 can only slide vertically inside the connecting sleeve 1.

[0027] Furthermore, the spring 17 is in a spiral shape, the upper end of the spring 17 is connected to the connecting plate 6, and the lower end of the spring 17 is fixedly connected to the inner bottom of the slide groove 28.

[0030] When the needle 4 is inserted into the charging end, the connecting plate 6 and the connecting rod 5 slide upward under the elastic action of the spring 7, driving the needle 4 to slide upward. Since the connecting plate 6 slides on the inner side of the slide groove 28, the slide groove 28 limits the position of the connecting plate 6, and then cooperates with the slide block 3 to slide on the inner side of the slide groove 2, thereby limiting the position of the connecting sleeve 1 for multiple times, making the position of the connecting sleeve 1 more stable and preventing the needle 4 from falling off.
