Abstract: A strand feeding device includes a seat body having a top end face and a mounting bore extending downwardly and inwardly from the top end face. A bobbin-mounting post extends upwardly from the top end face of the seat body. A bobbin is sleeved rotatably around the post, and has a lower end formed with engaging grooves, each of which is confined by a groove-defining wall. A spring-biased rod is movably disposed in the mounting bore, and has a rounded surface that engages the groove-defining wall of a selected engaging groove when the rod extends into the engaging groove.
