PROBLEM TO BE SOLVED: To improve convenience in threading by providing a high speed auxiliary device for threading which enables threading of a sewing machine needle to be easily completed at high speed, and also to improve safety in threading by forming a shielding plate thereby preventing a finger from coming in contact with the point of the sewing machine needle in threading. SOLUTION: The high speed auxiliary device for threading includes: a needle mounting head; the sewing machine needle; and a needle threader. The top end of the sewing machine needle is inserted by means of a shaft into the needle mounting head, and a threading hole is formed near the bottom end of the sewing machine needle, thereby a thread material is put through the threading hole to be set in the sewing machine needle. The needle threader and the needle mounting head are freely actively and pivotally connected to each other. The needle threader is mainly constituted of an upright plate and a thread hook. The plate is pivotally inserted into the needle mounting head in an axial direction and also is adjacent to the sewing machine needle. Both ear pieces are arranged in a projecting manner on both sides of the plate. The thread hook is provided at the front edge of the plate in a suspended manner and forms an open type curved hook body, so that the thread hook passes the threading hole in a reciprocated manner to catch the thread material, thereby performing an operation for threading the sewing machine needle and also improving convenience in threading.
