positioning structure for a reel

Abstract

An improved positioning structure for a reel is disclosed. The structure includes two corresponding external caps, a reeling disc, a leading cord, a spiral spring and a positioning ball, characterized in that the leading cord is respectively surrounding onto the external edge face of the upper frame position and the lower frame position, the cord in respective frame position are in opposite loosening and tightening state, and the upper frame is the pulling cord and the lower frame is the ready-to-rotate cord, and the cord is restricted by the positioning structure; the external cap has an inner edge face mounted with a multifunctional rail allowing the steel ball to position the cord in corresponding to counterclockwise rotation and clockwise rotation, urging the positioning ball to loosen and tighten the cord alternately, and the positioning ball is arranged at the sliding slot within the inner slot of the edge face of the reeling disc.
