An electrical charging device includes a top cover, a bottom cover and a fixing assembly. The fixing assembly includes a first button device, a second button device, and a lifting device. The first button device moves back and forth along a first axis with a first button pole retracting into the electrical charging device and protruding out from the electrical charging device. The second button device moves back and forth along a second axis, with a second button pole retracting into the electrical charging device and protruding out from the electrical charging device. The lifting device rises up and drops down along a third axis, with a contacting table carrying conductive pins protruding out from the electrical charging device and retracting into the electrical charging device, thereby making electrical contact with the electrical charging device. |
