The left sliding component 131 and the right sliding component 132 extend into the sliding groove 122 respectively, and the protruding ridge 123 is embedded in the groove, so that the sliding component moves along the sliding groove 122.
[0027] Specifically, the protruding rib 123 serves as a slide rail, and the sliding component moves up and down along the slide rail. In this embodiment, since the sliding component is fixedly mounted on the fixed component, the sliding part 12 is mounted above the fixed part 11 via the sliding component and can slide along the upper surface of the fixed part 11. In other embodiments, the slide rail and the slide groove can be interchanged, enabling the sliding component to slide within the sliding groove 122.
[0028] Preferably, the top ends of the left sliding component 131 and the right sliding component 132 are respectively provided with first magnetic elements, and the inner sides of the upper and lower ends of the sliding grooves 122 are respectively provided with second magnetic elements. That is, the second magnetic elements are located at both ends of the sliding stroke of the left sliding component 131 and the right sliding component 132. When the left sliding component 131 and the right sliding component 132 slide to both ends of the sliding grooves 122, the first magnetic elements and the second magnetic elements attract each other to fix the relative position of the sliding part 12 and the fixed part 11.
[0029] Specifically, when the sliding portion 12 and the fixed portion 11 are completely overlapped, the first magnetic element at the top of the sliding assembly attracts the second magnetic element at the top of the sliding groove 122. When the sliding portion 12 is pushed upward to the highest position, the first magnetic element at the bottom of the sliding assembly attracts the second magnetic element at the bottom of the sliding groove 122, fixing the sliding portion 12 to the top of the fixed portion 11.
[0030] Preferably, the sliding portion 12 further includes a first charging coil 124, a line adapter plate 125, and a snap-fit terminal 126.

[0031] Specifically, since the left sliding component 131 or the right sliding component 132 extends into the sliding groove 122 of the sliding portion 12, the lower groove 1311 communicates with the interior of the sliding portion 12, and the cable extends out of the sliding portion 12 through the lower groove 1311. The upper cover 111 of the fixing portion 11 has a cable mounting through hole at a position corresponding to the lower groove 1311. The cable enters the inner side of the upper cover 111 through the cable mounting through hole and connects to the base 20 along the cable routing groove 1111.
