The annular grooves 13 serve to allow the normal movement of the No. 1 pressure ring 11 and the No. 2 pressure ring 25. The annular grooves 13 are connected to the plug-in grooves 4. The outer surface of the No. 1 limiting column 7 is coaxially inlaid with the No. 1 pressure ring 11, and the outer surface of the No. 2 limiting column 10 is coaxially inlaid with the No. 2 pressure ring 25. The No. 1 pressure ring 11 serves to support the No. 1 pressure column 12.

[0023] Push-out posts 9 are extended from opposite ends of the two connecting plates 27, and the two push-out posts 9 extend from both sides of the comb seat 1 respectively. The push-out posts 9 and the push ring 28 are pushed by the spring body 29, so that the connecting plate 27 can move outward, so that the No. 1 limit post 7 and the No. 2 limit post 10 can be received in the annular groove 13 without extending into the plug-in groove 4, so that when the needle seat 5 is placed in or taken out of the plug-in groove 4, it will not be hindered by the No. 1 limit post 7 and the No. 2 limit post 10, and the push-out post 9 is slidably matched with the comb seat 1, and the end of the push-out post 9 is coaxially inlaid with a push ring 28, and the outer side of the push-out post 9 is wrapped with a spring body 29, one end of the spring body 29 is fixed to the push ring 28, and the other end of the spring body 29 is fixed to the side of the comb seat 1.

[0024] The top piece includes a plurality of guide columns 2 evenly distributed and fixedly installed on the lower end surface of the comb seat 1. A bearing seat 3 is arranged under the comb seat 1. The guide columns 2 play a role of guiding the bearing seat 3. The guide columns 2 pass through the lower end of the bearing seat 3, and the guide columns 2 and the bearing seat 3 are slidably matched. A through hole 22 is penetrated in the middle of the upper end of the bearing seat 3. The through hole 22 plays a role of allowing the swing arm 31 to pass through so that the bearing seat 3 can move normally. The swing arm 31 passes through the inside of the through hole 22. Both sides of the bearing seat 3 are fixedly installed with a plurality of inclined top plates 8 in a linear array. The other end of the No. 1 limiting column 7 and the other end of the No. 2 limiting column 10 are both attached to the inclined top plate 8. The inclined top plate 8 plays a role of pushing the No. 1 limiting column 7 and the No. 2 limiting column 10 so that the No. 1 limiting column 7 and the No. 2 limiting column 10 can be gathered together. The other end of the No. 1 limiting column 7 and the other end of the No. 2 limiting column 10 are both arranged in an inclined surface, so that they can fully contact the inclined top plate 8.

[0025] The front end of the swing arm 31 is penetrated and rotatably installed with a threaded rod 14. The threads at both ends of the threaded rod 14 are symmetrically arranged, which can drive the two threaded sleeves 15 to move toward each other. The outer surface of the threaded rod 14 is symmetrically tightened with two threaded sleeves 15. The outer surface of the threaded sleeve 15 is fixedly installed with a wheel seat 18. The wheel seat 18 plays a role in bearing the top wheel 20. The end of the wheel seat 18 is penetrated and inlaid with a wheel axle 19. The outer surface of the wheel axle 19 is coaxially installed with the top wheel 20. The wheel axle 19 plays a role in connecting the top wheel 20. Two extension seats 21 are symmetrically extended from the lower end surface of the supporting seat 3 near the middle, and the top wheel 20 is fitted on the extension seat 21. The extension seat 21 is supported by the top wheel 20 to drive the supporting seat 3 to move upward. The front and rear ends of the swing arm 31 are fixedly installed with a guide shell 16, and the interior of the guide shell 16 is fitted with a guide column 17. The guide column 17 passes through the end of the guide shell 16. The guide shell 16 and the guide column 17 play a role in guiding the top wheel 20. The guide column 17 passes through and is embedded in the wheel seat 18.

[0026] A swing shaft 33 is rotatably installed through the middle part of the swing arm 31, and a carrier frame 32 is inlaid at the end of the swing shaft 33. The swing shaft 33 serves to connect the swing arm 31, and a drive shaft 35 is rotatably installed at the end of the carrier frame 32. A lug 37 extends from the end of the drive shaft 35, and the drive shaft 35 is connected to an external motor for driving. A connecting shaft No. 1 36 is inlaid at the end of the lug 37, and a connecting frame 34 is rotatably installed at the end of the No. 1 connecting shaft 36. A connecting frame 34 is rotatably installed at the end of the No. 1 connecting shaft 36, and a No. 2 connecting shaft 38 is inlaid at the other end of the swing arm 31. The No. 1 connecting shaft 36 and the No. 2 connecting shaft 38 serve as a connecting transmission, and the end of the connecting frame 34 is rotatably installed on the end of the No. 2 connecting shaft 38. The driving shaft 35 drives the lug 37 to rotate in a circle, thereby driving the connecting frame 34 to move, so as to push and pull the swing arm 31, so that the swing arm 31 can swing back and forth with the swing shaft 33 as the center, thereby driving the yarn guide needle 6 on the comb seat 1 to move to comb the comb.

[0027] During assembly, multiple needle seats 5 are inserted into the insertion slots 4 on the comb seat 1 in a close fit, and then the threaded rod 14 is directly rotated to drive the two threaded sleeves 15 tightened on the outside of the threaded rod 14 to move toward each other, thereby driving the two top wheels 20 to move toward each other. At this time, the guide column 17 slides in the guide shell 16 to assist the top wheel 20 in moving, so that the top wheel 20 can roll from the bearing seat 3 to the extension seat 21 to lift the bearing seat 3, thereby moving the inclined top plate 8 on the bearing seat 3 upward, so that the multiple groups of No. 1 limiting columns 7 and the multiple groups of No. 2 limiting columns 10 are pushed by the inclined surface of the inclined top plate 8 to gather inward to be inserted. In the holes on the multiple needle seats 5, the cross protrusion 23 at the end of the No. 1 limiting column 7 and the cross groove 24 at the end of the No. 2 limiting column 10 are inserted into each other, so that the multiple needle seats 5 inserted into the plug-in slot 4 are simultaneously restricted in the plug-in slot 4, and when the No. 1 limiting column 7 and the No. 2 limiting column 10 gather inward to restrict the needle seats 5, the No. 1 pressure column 12 on the No. 1 pressure ring 11 and the No. 2 pressure column 26 on the No. 2 pressure ring 25 will be clamped on both sides of the needle seat 5 to firmly clamp and fix the multiple needle seats 5, so that the guide needle 6 can be assembled on the comb seat 1, and then the comb can be used.
