Hang device for a mobile phone

A hang device for a mobile phone comprises a hanging base, a spool, an elastic clip, and an outer cover. The hanging base provides a spool chamber for receiving the spool and the spool chamber at a center thereof extending outward a hanging spindle. The hanging spindle at an end thereof is attached with a spring to urge a projection piece and the projection piece at an end thereof extends a projection stop. The hanging base at the back thereof provides a back groove, and a thread hole is disposed near the spool chamber. The pool provides two opposite flanges with a pulled thread wound around a center between the flanges. A torsional spring is mounted in the spool with an end thereof being fixedly attached to the hanging spindle. One of the flanges provides a flange ring against the projection stop. The elastic clip is made of a bent sheet material and has a facial side thereof be joined to the hanging base and the other one of the facial sides be joined to the outer cover. The outer cover is attached to the elastic clip and is possible to engage with an end of the hanging. The pulled thread connects with the mobile phone through the thread hole so that the pulled thread can be drawn. When a retaining ring on the mobile phone is inserted into the back groove and push the projection piece, the projection stop can be free from the flange ring such that torsional spring can rewind the pulled thread to inward to complete the retraction of the pulled thread.
