AbstractA micro-type communication wire winder includes a housing, a rotary disk, a buckling piece, a communication wire and a spiral spring. The rotary disk is pivotally installed in the receiving groove of the housing and one surface thereof is installed with an axle bush and an outer circular cover with slots for fixing and winding a communication wire. While another surface is installed with a ring protrusion for receiving and engaging a spiral spring or receiving the spiral spring in a cavity adjacent to the rotary disk so that the spiral spring can be wound around the ring protrusion. Thus, the communication wire has a rewinding force applied thereon. The rim of the rotary disk is further installed with a tilt buckling groove. A buckling piece at the side of the housing obliquely resists against the rim of the rotary disk. Therefore, as the communication wire is pulled out for a predetermined length, the rotary disk can be buckled in the buckling groove by the buckling piece so as to retain a predetermined length. Thus, the micro-type communication wire winder has a simple structure and can be produced easily and conveniently. The communication wire will not be intricate or in tension so as to be used conveniently.
