Charge receiving coupler and power adapter for electronic device

摘要

An electronic device includes a charge receiving coupler. The charge receiving coupler includes a switching assembly and an inserting member. The switching assembly includes a gear transmission shaft, an elastic member, a first transmission wheel, a second transmission wheel fixed to the first transmission wheel, a button gear, and a button fixed to the button gear. The button gear engages with the first transmission wheel. The gear transmission shaft extends through the elastic member, the first transmission wheel and the second transmission wheel in that order. The inserting member defines a receiving groove, and the second transmission wheel is partly received in the receiving groove. The present disclosure further provides a power adapter which is matched with the charge receiving coupler.
