A fourth limit block 12 is arranged in the charging seat 1; when the fourth resilient tab 34 is in a natural state, a fourth gap is formed between the fourth stopper 12 and the fourth protrusion 341, and the fourth gap is an elastic range of the fourth protrusion 341. When the user completely places the cover body 2 in the cavity 101, and any one of the arc-shaped conductive contact strips presses the fourth protruding portion 341 to abut against the fourth protruding portion 341 at the fourth limiting block 12, the fourth protruding portion 341 further protrudes from the first through hole 102, so that the fourth protruding portion 341 partially protrudes from the corresponding first through hole 102 all the time, thereby preventing the fourth protruding portion 341 from being completely in the charging stand 1 and causing the first arc-shaped conductive contact strip 61, the second arc-shaped conductive contact strip 62, the third arc-shaped conductive contact strip 63, or the fourth arc-shaped conductive contact strip 64 to be unable to contact and conduct electricity.

The working process of the utility model is as follows: the user can place the cover body 2 into the cavity 101 with the circular cross section, the chamfer 21 of the cover body 2 automatically slides into the cavity 101 along the side wall of the cavity 101, so that the user does not need to align the cover body 2 with the cavity 101, when any arc-shaped conductive contact strip is pressed on any elastic sheet, the other arc-shaped conductive contact strips are correspondingly pressed on other elastic sheets one by one, the convex part of any elastic sheet is pressed down by utilizing the elasticity of the elastic sheet to be matched with the corresponding arc-shaped conductive contact strips, and due to the first arc-shaped conductive contact strip 61, the second arc-shaped conductive contact strip 62 and the third arc-shaped conductive contact strip 63, and the diameter of the circle enclosed by the fourth arc-shaped conductive contact strip 64, the first elastic sheet 31, the second elastic sheet 32 and the third elastic sheet 33, and the diameter of the circle where the fourth elastic sheet 34 is located is the same, so that the cover body 2 of the present application only needs to be placed in the cavity 101, and no matter how the cover body rotates, the charging assembly 4 and the battery 5 can be electrically connected.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
