[0002] Yarn is a material twisted from textile fibers. It is fine and light, and can be woven into different fabrics. It can also be blended with different fibers to make cotton, polyester, spandex, and other fabrics. It is used to sew clothing, process ropes, and other knitted fabrics. To improve textile efficiency, yarn is currently mostly transported by large-scale machinery.

[0003] Most common machines use bolts and nuts to fix the yarn guide during the transmission process. There is a round hole in the center of the yarn guide for the yarn to enter and exit. If the texture and hardness of the yarn vary, tension needs to be applied. The fixed yarn guide cannot be adjusted in position, nor can it be changed in time.

[0004] Now, a new type of mechanical yarn guiding device that is convenient for limiting and clamping is proposed to solve the above problems. Utility Model Content
