Stylus retaining mechanism for portable electronic device

摘要

A stylus retaining mechanism is configured for retaining a stylus. The stylus defines a cavity. The main body defines a receiving chamber to receive the stylus and a through hole above the receiving chamber. An elastic member is positioned at one end of the receiving chamber. A button assembly is attached in the cavity of the stylus. The button assembly includes a spring abutting the button. The through hole allows the button to partially extend through. The elastic member is compressed and abuts the stylus when the stylus is received in the receiving chamber.
