<p>The present invention relates to a fixating tool for a hook set of a sewing machine. More specifically, the fixating tool has an upper thread separation function to facilitate loop formation of an upper thread and to automatically cut the upper thread. Therefore, the fixating tool makes a continuous back-stitching process easy. The fixating tool (1) comprises an upper fixating tool (100) formed by integrating a joining part (110), an upper grip part (120) for fixating an upper portion of the hook set, and a protrusion piece (130); a lower fixating tool (200) that comprises a joining part (210) on which a joining hole (211) is punched and a joining protrusion (212) is formed to protrude, a lower grip part (220) extended from an end portion of the joining part (210) to fixate a lower part of the hook set, and a spring (230) which is joined with the center of the lower grip part (220) by a bolt; and a joining bolt (300) which joins the upper fixating tool (100) and the lower fixating tool (200) with a lower part of the sewing machine.</p> |
