Abstract
A wire-winding device comprising: an upper cover having a bottom surface and a slot deviating from a center of the bottom surface; a rotary base having an annular track on a top surface thereof, the annual track and the slot of the upper cover constituting an orbit; a spiral spring received in the rotary base; a transmission line winding around the rotary base; a lower cover assembled with the upper cover; and an elastic positioning element having a base and a positioning part extruding from the lower surface of the base, the base having an elastic part and a respective fixed part at each of two ends thereof, the elastic positioning element being moveable along the orbit in response to a rotational movement of the rotary base to avoid the transmission line to be tied a knot.
