Patent attributes
A charging device including a charging base and at least one hook portion is provided. The charging base has a receiving chamber for receiving a battery. The receiving chamber includes a first sidewall. The first sidewall has a first side and a second side opposing the first side. The hook portion is disposed on the first sidewall, positioned proximate to the first side of the first sidewall, and adapted to fix the battery in place. When the battery begins to rotate under an applied force and therefore disconnect from the hook portion, the fulcrum of the rotating battery is positioned proximate to the second side of the first sidewall. The battery can be firmly inserted into the charging device. It is easy to insert and take out the battery.
