[0029] Please see Figures 1-6 A tensioning mechanism for a pull wire includes a base plate 1, on which a tensioning assembly is provided. The tensioning assembly includes a placement frame 2 and a motor 3. The placement frame 2 is mounted on the base plate 1, and the motor 3 is mounted on the placement frame 2. A take-up wheel 4 is connected to the output end of the motor 3. A fixing frame 5 is mounted on one end of the placement frame 2. A moving groove 6 is provided on the fixing frame 5. A release assembly is mounted on one side of the fixing frame 5. The release assembly includes a stabilizing frame 7 and a threaded rod 8. The stabilizing frame 7 is mounted on one side of the fixing frame 5, and the threaded rod 8 is mounted on the stabilizing frame 7. A mounting frame 9 is slidably connected to the threaded rod 8.

[0030] A movable frame 10 is slidably connected to the movable groove 6, and a pressure roller 11 is rotatably connected to the movable frame 10.

[0031] A screw 12 is rotatably connected to the movable frame 10, and the screw 12 is threadedly connected to the fixed frame 5.

[0032] Nuts 13 are threadedly connected to the threaded rod 8. Multiple nuts 13 are provided. Nuts 13 are tightly attached to both ends of the mounting bracket 9. A placement rod 14 is slidably connected to the mounting bracket 9. A mounting wheel 15 is rotatably connected to the placement rod 14. A fixing sleeve 16 is installed on the mounting bracket 9. A rotating ring 17 is rotatably connected to the fixing sleeve 16. A through groove 18 is opened on the rotating ring 17.

[0033] A fixed plate 19 is installed on the fixed sleeve 16, and a movable plate 20 is slidably connected to the fixed sleeve 16. A spring 21 is connected between the movable plate 20 and the fixed plate 19. Movable rods 22 are evenly installed on the movable plate 20, and movable blocks 23 are installed on the movable rods 22. There are two movable blocks 23. The movable blocks 23 are adapted to the through groove 18. A threaded ring 24 is threadedly connected to the fixed sleeve 16. One end of the movable rod 22 is inserted into the threaded ring 24, and one of the movable blocks 23 is in close contact with the threaded ring 24.

[0034] In this embodiment, one end of the yarn is wound around the mounting wheel 15, and the other end is wound around the take-up wheel 4. The motor 3 is started, causing the take-up wheel 4 at the output end to rotate, thus winding the yarn. The yarn to be wound passes through the fixing frame 5, making it tightly against one side of the pressure roller 11. When the position of the pressure roller 11 needs adjustment, the screw 12 is rotated along the fixing frame 5. This rotation causes the movable frame 10, which is rotatably connected to one end of the screw 12, to slide along the movable groove 6, thereby adjusting the yarn tension. After winding the yarn on the mounting wheel 15, when the mounting wheel 15 needs to be replaced, the nut 13 is rotated along the threaded rod 8 to remove it, and then the mounting frame 9 is rotated along the threaded rod 8 to remove it. When the fixing between the rotating rod and the mounting bracket 9 is released, the moving plate 20 slides along the fixing sleeve 16, causing the moving rod 22 and the moving block 23 on the moving plate 20 to slide, and aligning the moving block 23 with the through groove 18. After the moving block 23 passes through the through groove 18, the rotating ring 17 rotates along the fixing sleeve 16. When the moving plate 20 moves, the spring 21 between the fixing plate 19 and the moving plate 20 is compressed. After the moving block 23 passes through the rotating ring 17, the moving plate 20 is released, and the elastic potential energy of the spring 21 causes the moving block 23 to be stuck on the rotating ring 17. When the moving rod 22 moves, one end of the moving rod 22 moves out of the threaded ring 24, thus releasing the fixing of the threaded ring 24.

[0035] Please see Figure 5-6As an embodiment of a tensioning mechanism for a stabilizing component: a stabilizing component is provided on the fixed sleeve 16. The stabilizing component includes a fixed rod 25 and a fixed groove 26. The fixed rod 25 is slidably connected to the placement rod 14, the mounting bracket 9 and the fixed sleeve 16. The fixed groove 26 is opened on the fixed rod 25. A first rotating rod 27 is rotatably connected to the fixed sleeve 16.

[0036] A connecting block 28 is installed on the first rotating rod 27, and a moving ring 29 is slidably connected to the fixed sleeve 16.

[0037] A second rotating rod 30 is provided for the rotatable connection between the connecting block 28 and the moving ring 29.

[0038] More specifically, after releasing the threaded ring 24 from its fixation, the threaded ring 24 is rotated along the fixed sleeve 16. During this rotation, the moving ring 29 is pushed to slide along the fixed sleeve 16. During this movement, the first rotating rod 27 is rotated along the fixed sleeve 16. The first rotating rod 27 drives the second rotating rod 30 to rotate via the connecting block 28, thereby removing the connecting block 28 from the fixed groove 26 and releasing the fixation on the fixed rod 25. Then, the fixed rod 25 is slid out along the fixed sleeve 16 and the mounting bracket 9, releasing the fixation between the placement rod 14 and the mounting bracket 9.

[0039] In summary, during the use or operation of the entire equipment: one end of the yarn is wound onto the mounting wheel 15, and the other end is wound onto the take-up wheel 4. The motor 3 is started, causing the take-up wheel 4 at the output end to rotate, thus winding the yarn. The yarn to be wound passes through the fixed frame 5, pressing it tightly against one side of the pressure roller 11. When the position of the pressure roller 11 needs adjustment, the screw 12 is rotated along the fixed frame 5. This rotation causes the movable frame 10, which is rotatably connected to one end of the screw 12, to slide along the movable groove 6, thereby adjusting the yarn tension. After winding the yarn onto the mounting wheel 15, when the mounting wheel 15 needs to be replaced, the nut 13 is removed by rotating along the threaded rod 8. Then, the mounting frame 9 is rotated along the threaded rod 8. Remove the rotating rod and release the fixing between the rotating rod and the mounting bracket 9. Then, slide the moving plate 20 along the fixing sleeve 16. During the sliding movement, the moving rod 22 and the moving block 23 on the moving plate 20 will slide and move, so that the moving block 23 is aligned with the through groove 18. After the moving block 23 passes through the through groove 18, rotate the rotating ring 17 along the fixing sleeve 16. When the moving plate 20 moves, the spring 21 between the fixing plate 19 and the moving plate 20 will be compressed. After the moving block 23 passes through the rotating ring 17, release the moving plate 20. Under the action of the elastic potential energy of the spring 21, the moving block 23 will be stuck on the rotating ring 17. When the moving rod 22 moves, one end of the moving rod 22 will be removed from the threaded ring 24, so that the fixing of the threaded ring 24 is released.

[0040] After releasing the threaded ring 24 from its fixation, rotate the threaded ring 24 along the fixed sleeve 16. During rotation, the threaded ring 24 pushes the moving ring 29 to slide along the fixed sleeve 16. During this movement, the moving ring 29 moves the first rotating rod 27 along the fixed sleeve 16. The first rotating rod 27 drives the second rotating rod 30 to rotate via the connecting block 28, thereby removing the connecting block 28 from the fixed groove 26 and releasing the fixation on the fixed rod 25. Then, slide the fixed rod 25 along the fixed sleeve 16 and the mounting bracket 9 to release the fixation between the placement rod 14 and the mounting bracket 9.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
