Abstract: The present invention relates to a two-way cable winding reel. The reel includes a housing, a rotator, a worm spring, and a cable. The rotator has several protrusions on one side, and the housing has a movable stopper. One end of the stopper forms a pawl that extends between any two of the protrusions.

The other end of the stopper protrudes through the housing such that a user may engage or disengage the stopper to cause the pawl to disengage from the protrusions and permit retraction of the cable to a desired length.
