Wire-winding device

A wire-winding device assembly comprising:

• cover means defining a receiving space therein;
• a stationary slot formed in the cover means;
• a rotary base located around the receiving space and rotatable with regard to the cover means, said rotary base defining an annual track thereof;
• a torsion spring fixed to both said cover means and said rotary base to constantly urge the rotary base back to move to an original position;
• a transmission wire winding around the rotary base and adapted to actuate the rotary base to rotate when said transmission wire is pulled outwardly;
• and
• an elastic positioning element defining a first section received within and moveable along said slot and a second section received within and moveable along annual track;
• wherein
• a depth of said annual track varies in a vertical direction to guide the second section of the elastic positioning element to move therealong, and said elastic positioning element performs elasticity thereof in the vertical direction to comply with the variant depth of said annual track during moving along the annual track.

• a transmission wire winding around the rotary base and adapted to actuate the rotary base to rotate when said transmission wire is pulled outwardly;
• and
• an elastic positioning element defining a protruding section received within and moveable along annual track so as to be moveable relative to the cover means correspondingly;
• wherein
• a depth of said annual track varies in a vertical direction to guide the protruding section of the elastic positioning element to move therealong, and said elastic positioning element performs elasticity thereof in the vertical direction to comply with the variant depth of said annual track during moving along the annual track;
• wherein
• the annual track includes an inner annual path and an outer annual path linked to each other with therebetween a joint which defines a latching position where the elastic positioning element resists the torsion spring to have the rotary base is in a working position instead of the original position.
