The first guide wheel 106 is relatively large in size and coincides with the direction of movement of the yarn, ensuring that the yarn will not escape from the guide of the first guide wheel body 106. The upper end of the workbench 101 is connected and fixed with a support plate 102 by bolts, and a movable column 103 runs through the interior of the support plate 102. The movable column 103 is equipped with a yarn coil bobbin 104, and the lower end of the workbench 101 is connected and fixed with a support leg 113 by welding.

[0039] When in use, first install the yarn coil bobbin 104 on the movable column 103 and the support plate 102, and guide the yarn arrangement on the first guide wheel 106, the positioning ring 111 and the second guide wheel 201. When the yarn is guided by the second guide wheel 201, the swinging guide wheel will automatically adjust the swinging of the second guide wheel 201 according to the movement direction and tension change of the yarn. The second guide wheel 201 can swing appropriately and rotate up and down on the door frame 202. The vise frame 204, the fixed plate 205 and the latch bolt 209 on the support frame 210 and the first movable bolt 206 and the second movable bolt 211 rotate, and the guide column 212 moves up and down inside the guide sleeve 213. The second guide wheel 201 can swing flexibly through the rebound force and contraction of the spring 207, and the yarn is transported to the sock knitting machine through the outlet wheel 108.

[0040] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
