The other end of the telescopic rod 3 is fixedly installed on the outer surface of the support tube 1. A spring 4 is arranged on the outer surface of the telescopic rod 3. One end of the spring 4 is connected to the surface of the support tube 1, and the other end of the spring 4 is connected to the surface of the support block 2. A suspended support structure is arranged on the lower surface of the support tube 1. The suspended support structure can realize support and guidance of the support tube 1 during the rotation process, thereby reducing the wear of the support tube 1 during the rotation process. The suspension support structure includes a base 5, which is a cylindrical structure with an open upper surface. A guide cylinder 6 is fixedly installed on the bottom surface of the base 5.

The slider 9 is fixedly connected to the inner wall of the guide cylinder 6.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, when using the device, the lower end of the yarn tube is inserted into the outer surface of the support block 2, so that the inner surface of the yarn tube wraps the support block 2, and the yarn tube can be supported by the telescopic rod 3 and the spring 4, so that the yarn tube is sleeved on the outer surfaces of the support tube 1 and the support block 2. After the yarn tube is fixed to the support tube 1 and the support block 2, during the rotation of the yarn tube, the support tube 1 and the support block 2 rotate synchronously. When the support tube 1 rotates, the slide groove on the outer surface of the support tube 1 is guided by the slider 9 on the inner wall of the guide tube 6 to ensure that the rotation process of the support tube 1 is not offset, and the upper magnetic ring 7 and the lower magnetic ring 8 arranged at the lower end of the support tube 1 repel each other, ensuring that the lower end of the support tube 1 has no contact with the bottom surface of the guide tube 6, thereby reducing the wear of the support tube 1 during the rotation process.

[0040] An airbag support structure is arranged inside the support tube 1, and the airbag support structure can realize the horizontal reinforcement process of the support block 2. The airbag support structure includes a No. 1 airbag 10, and the No. 1 airbag 10 is arranged in a groove on the upper surface of the support tube 1. The surface of the No. 1 airbag 10 is a compressible flexible material. A No. 2 airbag 11 is arranged on the outer surface of the support tube 1. The No. 2 airbag 11 is a circular ring structure. The surface of the No. 2 airbag 11 is fixedly connected to the surface of the support tube 1. A plurality of No. 2 airbags 11 are arranged in parallel up and down, and the plurality of No. 2 airbags 11 are connected by pipelines. The No. 2 airbag 11 is located between the support tube 1 and the support block 2, and the bottom The No. 2 airbag 11 is provided with a pipeline penetrating through the surface of the support tube 1 and connected with the No. 1 airbag 10. A push plate 12 is provided above the No. 1 airbag 10. The push plate 12 is slidably connected to the inner wall of the support tube 1. A limit block 14 is fixedly installed on the inner wall of the support tube 1. The limit block 14 is a circular ring structure, and the inner diameter of the limit block 14 is smaller than the diameter of the push plate 12. The inner surface of the limit block 14 is provided with a thread. A push rod 13 is provided on the inner surface of the limit block 14. The main body of the push rod 13 is a smooth round rod. The upper section of the outer surface of the push rod 13 is provided with an external thread and is threadedly connected with the inner surface of the limit block 14. The lower end of the push rod 13 contacts the upper surface of the push plate 12.

[0041] like Figure 1 , Figure 5 and Figure 6 As shown, in the process of horizontally fixing the yarn tube, the yarn tube is located on the outer surface of the support block 2, and the handheld push rod 13 is pushed toward the inside of the support tube 1. The push rod 13 pushes the push plate 12 downward to move, and the push plate 12 squeezes the No. 1 airbag 10 downward, causing the No. 1 airbag 10 to deform and compress. The air inside the No. 1 airbag 10 enters the external No. 2 airbag 11 along the connected pipe, causing the No. 2 airbag 11 to expand and bulge. The bulged No. 2 airbag 11 plays a clamping and fixing role between the support tube 1 and the support block 2, and fixes the yarn tube in the horizontal direction. At the same time, the thread on the outer surface of the push rod 13 is connected to the thread on the inner surface of the limit block 14 to fix the push rod 13 to the support tube 1.

[0042] The lower surface of the support tube 1 is provided with a trigger structure, which can realize the vertical fixation of the yarn tube, and the trigger structure includes an electromagnet 15, which is a circular ring structure, and the electromagnet 15 is sleeved on the outer surface of the guide tube 6, and the electromagnet 15 is fixedly connected to the bottom surface of the base 5, and the electromagnet 15 is connected to the external power supply through a wire, and a magnetic block 16 is provided above the electromagnet 15, and the magnetic block 16 is circular, and the lower surface of the magnetic block 16 is connected to the bottom surface of the base 5 through another group of telescopic rods 3, and the electromagnet The magnetic poles of the iron 15 and the magnetic block 16 repel each other. A limiting structure is provided on the upper surface of the support block 2. The limiting structure cooperates with the trigger structure to fix the yarn tube in the vertical direction. The limiting structure includes a clamping plate 17. The clamping plate 17 is slidably connected to the upper surface of the support block 2. The clamping plate 17 is driven by a clamping block 18. The main part of the clamping block 18 is a cylindrical structure with an open lower surface. The outer surface of the cylinder of the clamping block 18 is provided with a sloped protrusion. The protrusion on the outer surface of the clamping block 18 is aligned with the side of the clamping plate 17 close to the support tube 1.

[0043] like Figure 2 , Figure 7 , Figure 8 and Fig. 9 As shown, after the yarn tube is sleeved on the outer surface of the support block 2, the lower end of the yarn tube is in contact with the upper surface of the magnetic block 16, and the magnetic block 16 is pushed downward under the action of gravity to contact the electromagnet 15. In the process of pushing the push rod 13 downward to fix it with the support tube 1, the block 18 on the outer surface of the push rod 13 moves downward synchronously. When the sloped protrusion on the surface of the block 18 contacts the blocking plate 17, the block 18 that continues to move downward will push the blocking plate 17 outward to slide on the upper surface of the support block 2, so that one side of the blocking plate 17 extends out of the surface of the support block 2, limiting the upper end of the yarn tube, turning on the power of the electromagnet 15, starting the electromagnet 15, and the electromagnet 15. After the power is turned on to generate magnetic force, under the action of the magnetic force, the electromagnet 15 pushes the magnetic block 16 upward, and the magnetic block 16 moves upward smoothly under the action of the telescopic rod 3. The upward moving magnetic block 16 pushes the yarn tube on the outer surface of the support block 2 to move upward. After contacting the blocking plate 17, the yarn tube is fixed in the vertical direction under the action of the blocking plate 17 and the magnetic block 16. When the yarn tube is disassembled, the power supply of the electromagnet 15 is disconnected, the magnetic force of the electromagnet 15 is lost, and the magnetic block 16 and the yarn tube move downward back to the original position under the action of gravity. The push rod 13 is rotated in the opposite direction for disassembly, so that the blocking plate 17 loses the thrust of the blocking block 18, and the yarn tube can be pulled out upward at this time.

[0044] Working principle: The yarn tube is sleeved on the outer surface of the support tube 1 and the support block 2, and the push rod 13 is held and pushed downward. The push rod 13 drives the push plate 12 to move, and the push plate 12 squeezes the No. 1 airbag 10, so that the air in the No. 1 airbag 10 enters the external No. 2 airbag 11. The inflated No. 2 airbag 11 is supported between the support tube 1 and the support block 2 to ensure that the yarn tube is fixed in the horizontal direction. The push rod 13 is fixed with the limit block 14 by a thread. In this process, the push rod 13 drives the block 18 to move, and the block 18 pushes the block plate 17 to slide. The sliding block plate 17 limits the upper end of the yarn tube, and the electric start The power supply of the magnet 15, under the action of magnetic force, the electromagnet 15 pushes the magnetic block 16 upward, and the magnetic block 16 pushes the yarn tube upward to contact the positioning plate 17, thereby realizing the fixing process of the yarn tube in the vertical direction. When the yarn tube rotates, the yarn tube drives the support tube 1 and the support block 2 to rotate, and the support tube 1 rotates under the guidance of the slider 9 on the inner wall of the guide tube 6 to avoid the rotation deviation of the support tube 1, and the lower end of the support tube 1 uses the repulsive force between the upper magnetic ring 7 and the lower magnetic ring 8 to ensure that the lower end of the support tube 1 is not in contact with the bottom surface of the guide tube 6, thereby reducing the wear of the support tube 1 during the rotation process.

[0045] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
