A rotary positioning component is provided on the fixing plate 10, and the rotary positioning component is connected to the rotary adjustment disc 20.

[0022] Specifically, the rotation positioning component includes two blocking columns 11 movably installed on one side of the fixed plate 10. The two blocking columns 11 are arranged in a circumferential array. Two blocking holes 14 are formed on one side of the rotation adjustment disc 20. One end of each of the two blocking columns 11 movably penetrates through the two blocking holes 14 respectively. The same end plate 12 is fixedly installed at one ends of the two blocking columns 11. One end of a tension spring 13 is fixedly installed on one side of the end plate 12. The other end of the tension spring 13 is fixedly installed on one side of the fixed plate 10. When it is necessary to adjust the spinning diameter, pull the end plate 12 on the rotation positioning component. The tension spring 13 is pulled, and the two blocking columns 11 are disengaged from the blocking holes 14, so that the rotation adjustment disc 20 can be rotated. After rotating half a turn, the spinneret plate 7 with another aperture will correspond to the spinneret 2. Release the end plate 12. Under the elastic force of the tension spring 13, the two blocking columns 11 can penetrate through the blocking holes 14 to fix the position of the adjusted spinneret plate 7.
