Abstract
An automatic winding module of a wire for Bluetooth headset with an improved wear resistance function of a rotation axis, which firmly maintains a rotation axis without twist of the rotation axis even in case of using it for a long time, thereby preventing breakaway between a terminal and a PCB pattern, to prevent a short circuit from occurring.
