When the pull rope 16 moves, the top splint 19 will be subjected to tension and be in an open state. Then, the top splint 19 will transfer the elastic force to the bottom splint 19 through the elastic rope 15 so that it is also in an open state. At this time, the device can adjust the size of the splint 19. Finally, the splint 19 can guide and transmit yarns of different thicknesses.
