The base 3 includes an upper cover 31 and a lower cover 32, the adapter cover 21 and the adapter body 22 cover each other, the connecting plate 23 is connected to the adapter body 22 and clamps the upper cover 31 of the base 3 between the connecting plate 23 and the adapter body 22, so as to realize the rotatable connection between the adapter 2 and the base 3.

[0032] In this embodiment, the charging module 1 includes a charging module bottom shell 12 and a charging module cover plate 11, and the charging module bottom shell 12 and the charging module cover plate 11 are overlapped to form a cavity for accommodating the charging coil. The charging module bottom shell 12 is provided with a plurality of snap-in protrusions 129, and the charging module cover plate 11 is provided with a plurality of snap-in recesses 119, and the snap-in protrusions 129 and the snap-in recesses 119 are snap-into each other to realize the assembly of the charging module bottom shell 12 and the charging module cover plate 11. The charging module bottom shell 12 is provided with a connecting arm 121, and a rotating shaft 122 is provided on both sides of the connecting arm 121, and a rotating shaft sleeve cooperating with the rotating shaft 122 is provided in the adapter 2.

The half-axle sleeve 2213 and the half-axle sleeve 213 form the rotating shaft sleeve, which cooperates with the rotating shaft 122 , so that the charging module 1 can be rotatably connected to the adapter 2 .

[0033] In this embodiment, the adapter body 22 includes an upper plate 221, a lower plate 222, and a connecting ring 223 connected to the lower plate 222. The upper cover 31 of the base 3 is provided with a flange ring 311, and the flange ring 311 is provided with a through hole 312.
