Mobile phone with a fastener capable of bidirection movement

Abstract

A mobile phone comprises: a casing, a battery cover, a fastener, an elastic member and a ring. The casing has a receiving room and an opening connected to the receiving room. The battery cover is disposed on the casing removably. The fastener is movably disposed in the receiving room along a first direction and a second direction. The elastic member disposed in a bottom of the receiving room is against the fastener to provide a resilient force parallel to the first direction so as to couple the fastener and the battery cover. The ring is fastened on the casing via the opening. When the fastener is pressed, the fastener moves to the first direction to depart the battery cover from the casing. When the fastener is pushed, the fastener moves to the second direction to depart the ring from the casing.

Dependencies are inferred from the claim text.
