[0002] The twist stopper is one of the key parts of the chemical fiber texturing machine. It is a device that prevents cotton from turning into coils again after being spun into cotton yarn and stops spinning in time. The elastic quality of the chemical fiber is directly related to the working performance of the twist stopper.

[0003] When cleaning or maintaining the twist stopper of the texturizing machine, it is necessary to remove the twist stopper from the cross arm of the texturizing machine. With the development of technology, the twist stopper is generally fixed by snap-on and screw-fixed, which is time-consuming and laborious to remove, and there is a risk of screw damage after a long time, which makes it difficult to remove and then affects production.
