发明名称 POSITIONING PEG STRUCTURE OF A SINGLE-PULL REEL
摘要 A positioning peg structure of a single-pull reel is disclosed. The positioning structure provides the function of positioning of the cord after a second pull following the first pull of the cord. When the cord is pulled to rotate one round, a first positioning mechanism is formed. Thus, when the cord is pulled in one direction once, the cord is controlled to provide a plurality of multiple positioning such that the pulling distance can be precisely controlled.
