Abstract
A single free-end wire reel includes a leveled area disposed on a rotary member to level arc tracks and a gap formed at the intersection of the arc tracks to change the motion track of a limit block. The present invention not only keeps the limit block to have a dual-positioning function when doing a circular motion but also controls the length of a wire exactly, providing a smooth operation when extending or extracting the wire.
