[0002] Sewing machine thread clamp is a very important component in sewing machine, its main function is to adjust the tension of thread. By controlling the tightness of thread clamp, the tension of thread in the sewing process can be determined, thereby affecting the appearance and firmness of stitch.

[0003] According to a kind of sewing machine thread clamp (public number: CN212611283U) shown, the rubber sleeve in the above application is designed, when thread clamp is installed in the interior of machine, the rubber sleeve will contract according to the size of installation port, and in the process of contraction, the rubber sleeve will extrude fixed connection sleeve, so that fixed connection sleeve forms rebound when being extruded, connects and reinforces the rubber sleeve and machine inner wall, avoids wobble problem in the process of working. Traditional sewing machine thread clamp usually adopts simple mechanical structure to control the tension of thread, and the adjusting mode is relatively single, which is difficult to accurately meet the needs of different fabrics and sewing processes. In addition, some old thread clamps need to use tools when adjusting, which is complicated and inefficient. This not only increases the workload of operators, but also easily makes mistakes during adjustment, affecting the sewing quality. Therefore, we provide a sewing machine thread clamp with adjusting structure. UTILITY MODEL CONTENTS
