Description of the Invention: Technical Field of the Invention The present invention relates to a needle thread feeder device for a sewing machine, and more particularly to a design that can be driven by a needle clamp group, a spool set, a dial plate and a power pack. The group pushes and pulls the wire drawing group, so that the threaded shaft group drives the dial plate to open or withdraw the needle thread clamp group, so as to have the effect of adjusting the thread amount and reducing the length of the excess seaming thread head, and is suitable for various sewing machine models or the like. By. [Prior Art] According to the conventional automatic thread cutting sewing machine, when the sewing is finished and the automatic thread cutting operation is completed, a needle thread is retained on the needle (the length of the thread is about 40 mm from the needle hole) to avoid the next seaming. The thread slipped out of the pinhole, causing trouble to re-thread. However, the needle thread will be pulled under the cloth at the next seam and then pulled down by the hook, and a redundant thread is formed under the first needle of the cloth, which is easy to cause a poor appearance or requires labor. Then remove the excess thread length. Yu Yu, there is a way for the sewing machine manufacturer to reduce the length of the seaming thread. As disclosed in the Chinese Patent Publication No. CN 101372797A, the "sewing machine and the method of using the seam quilting line" are Three sets of electromagnets with timing control are added to the conventional automatic slash _:, but the mechanism is complicated and the cost is too high, so the actual use still does not meet the needs of the user. SUMMARY OF THE INVENTION The main purpose of the invention is to provide a needle thread feeder device, a body, at least a needle clamp group, a threaded shaft set, a dial, at least a fulcrum, a line. The combination design of the hanging plate and a power group uses the power group to push and pull the wire shaft group to drive the dial plate to push in or out of the needle thread clamp group. When the needle thread 201135002 is set to the top side, the fulcrum and the wire hanging plate are used. The line quantity is the shortest and the smoothest; when the dial board exits the needle thread, the needle thread clip group records the stitching line, and the power group continues to push the thread shaft group to tension the stitching line, and the thread amount between the pivot point and the wire hanging board becomes long, and The needle clamp group clamps the suture so that the suture cannot obtain the thread between the fulcrum and the hanging plate from the needle thread supply, and only the amount of thread can be recovered from the front end of the suture head, thereby shortening the length of the sewing thread and saving cost. purpose. It is easy to use, reduce unnecessary thread and save cost, and increase the overall practicability and convenience.

The spool assembly 30 is driven to move the dial 40, wherein the dial 40 is driven by the threaded shaft set 30 to drive the first needle clip 2 3 of the needle clamp group 2 and the first needle clip 2 4 And will open, and the suture 1 is bent through the hollow body 311 of the middle section of the movable shaft group 30 through the fulcrum 50, and then passes through the thread hole 61 of the wire hanger 60, and continues through the suture The pressure adjustment group g 〇 针 夹 2 2 2 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' When the air hole 74 is in the air, the sliding rod 71 can be pushed forward, and the sliding rod 71 is screwed to the front end of the threaded shaft 31 of the threaded shaft group 30, thereby interlocking the thread shaft assembly 30 and driving the dial 40, wherein The first needle thread clip 2 3 and the second needle thread clip 2 4 of the needle thread clamp group 20 are driven by the threaded shaft group 30 to make the first needle thread clip 2 3 and the second needle thread clip 2 4 The suture 1 is clamped and cannot be pulled, and the sliding rod 71 continues to slide to drive the bobbin set 3 〇 and the dial 4 0 to slide before the stern plate 80, and the suture 1 passes through the fulcrum 5 〇 The hollow body 311 of the middle portion of the shaft group 3 0 passes through the line hole 61 of the wire hanging plate 60, and continues to pass through the needle thread clamp group 20 of the sewing thread pressure adjusting group 9 ,, so that the fulcrum 5 〇 and the wire hang The amount of thread between the plates 6 变 becomes longer, and the suture 1 is clamped by the needle thread clamp group 20, so that the suture can obtain the thread amount between the fulcrum 50 and the wire hang plate 60 from the needle thread supply, only from the seam line The front end of the hoe is used to recover the amount of wire, thereby adjusting the amount of the wire to be used by the wire sill. The effect of the above-mentioned mechanism movement on the needle thread is to pull the needle thread back up between the hook of the first needle of the first stitch (when the needle is gradually lifted up) and the movement of the sky to the bottom dead center (Fig. Not shown) 'The length of the suture 1 remaining under the cloth is controlled within the allowable range (where the length of the suture 1 is approximately equal to the distance between the fulcrum 50 and the wire hanger 6 ,, because of the line axis group 3 (10) over & sleeve 201135002 length difference; in order to achieve this, the invention only attaches an action mechanism of the needle thread supply to the automatic tangential slit _ for f, which can shorten the length of the stitching thread; Therefore, the invention has the effects of reducing unnecessary thread heads and saving costs, and increasing the overall practicability. From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the above-mentioned objects, and the patent application is in accordance with the provisions of the Patent Law.
