1 results about "Eye Fatigue" patented technology

The invention discloses a sewing machine threader and an industrial sewing machine applying the same. Based on the principles of spring elastic deformation and magnetism and aiming at the requirementfor automatic threading at a high-strength eye use state in sewing production, the developed industrial sewing machine threader serves as an independent part and can be selectively assembled with theindustrial sewing machine; and the developed industrial sewing machine threader is conductive to reducing eye fatigue of workers, meanwhile, the threading action accuracy is improved, and the labor hour cost is saved. According to the technical scheme, the industrial sewing machine threader comprises a fixing base, a threader main body is rotationally connected to the fixing base, an included angle is formed between the initial position of the threader main body and the fixing base, a space formed by the included angle is used for containing a sewing machine needle, limiting between the threader main body and the fixing base is achieved through magnetic attraction, and a movably stretchable crochet hook for threading is arranged on the threader main body.
