[0025] The L-shaped fixing block 16 can limit one side of the yarn guide rod 15, making it easy for the yarn guide rod 15 to be kept in a vertical position. The gear 13 is connected to the switching frame 14, so that the gear 13 can rotate synchronously with the switching frame 14 when the switching frame 14 rotates. The connecting piece 6 can support the rotation of the switching frame 14. When the gear 13 rotates, the gear 13 can drive the rack 17 to adjust its height through the meshing of the gear 13 and the rack 17. When the rack 17 rises and falls, the connecting piece 6 can guide the movement of the rack 17. The crossbar can connect the guide wheel 22 and the rack 17, so that the guide wheel 22 and the rack 17 can be raised and lowered synchronously, thereby changing the working height of the guide wheel 22.
