Abstract: This invention is a wire coiling box structure comprising of a top cover, a bottom cover, and a spring in between. When turning the top cover and the bottom cover, the spring will jack up the top cover and open the box. Then the extra wire can be put into the box through the opening and wound around the tube on the bottom cover. Press the two ends of the wire down into the gaps on the outer wall of the bottom cover, close the two covers, and turn them in reverse direction to fasten firmly. Then the extra wire is not only concealed in the box, but also hard to be pulled out by force.
