The first driving structure 304 is fixedly connected to the fixed seat 201 to drive the rotation of the rotating arm 302. The angle of the rotating arm can be changed by remotely adjusting the first driving structure 304 through the PLC, so that the position angle of the yarn guide wheel 2 can be changed. The second driving structure 305 is fixedly connected to the rotating arm 302 to drive the rotation of the yarn guide wheel support 303.
