Abstract
A battery charger includes a bottom case comprising a bottom surface. A cover is attached on the case defining a curved groove and two openings. A seat is fixed on the bottom surface and comprises a first inclined surface inclined relative to the bottom surface. A slider is slidably arranged in the case and comprises two spring contacts aligned with the two openings, respectively. The slider is slidable to a position where the spring contacts protrude out of the two openings. The driving member is arranged in the bottom case and includes a post protruding out of the curved groove. A mating member comprises a second inclined surface inclined relative to the bottom surface engaging the first inclined surface. A first means is for allowing the mating member to slidably connect the mating member to the driving member and allowing the mating member to rotate together with the driving member.
