A plurality of groups of blade seat insertion slots 8 are opened on the surface of the sleeve 2. A blade seat 9 is fixed at the end of the blade 10 away from the brush hair 11. The blade seat 9 is movably inserted into the blade seat insertion slot 8. A screw hole 3 is opened on the surface of the fixed shaft 1. A screw 4 is rotatably connected to the surface of the sleeve 2. The screw 4 is installed in the screw hole 3 by threaded connection. A gasket 5 is sleeved on the screw rod of the screw 4. Keyways 6 are opened on both the shaft body of the fixed shaft and the inner wall of the sleeve 2. One end of a flat key 7 is movably inserted into the keyway on the shaft body of the fixed shaft 1, and the other end of the flat key 7 is movably inserted into the keyway on the inner wall of the sleeve 2. The blade seat insertion slot 8 has a "convex" - shaped groove structure, and the blade seat 9 has a "convex" - shaped plate - like structure.

[0023] In actual use, the fixed shaft 1 and the sleeve 2 are installed through the threaded connection between the screw hole 3 and the screw 4. A washer 5 is placed on the screw 4 to prevent loosening and to prevent the sleeve 2 from falling off the fixed shaft 1. At the same time, a keyway 6 is opened on the inner wall of the fixed shaft 1 and the sleeve 2. The sleeve 2 is circumferentially limited by the keyway 6 and the flat key 7. The blade seat 9 is inserted into the blade seat insertion groove 8 opened on the surface of the sleeve 2, thereby realizing the movable installation of the blade 10 and the sleeve 2. After the yarn suction device is used up, the screw 4 can be unscrewed from the screw hole 3, and then the sleeve 2 can be removed from the fixed shaft 1 to clean the bristles 11, so as to more easily remove the fine yarn on the bristles 11 and restore the adhesion of the bristles 11. When the bristles 11 on the surface of a certain group of blades 10 are severely worn, the blade seat 9 fixed on the surface of the group of blades 10 can be pulled out from the blade seat insertion groove 8, and then the group of blades 10 can be replaced.

[0024] Example 2: Based on Example 1, in order to make the installation of the blade seat 9 in the blade seat insertion groove 8 more secure, a limiting plate mounting groove 12 is opened on the inner wall of the top opening of the blade seat insertion groove 8. One end of the limiting plate 13 is movably inserted into the limiting plate mounting groove 12, and the other end of the limiting plate 13 is movably inserted into the blade seat insertion groove 8 and abuts against the top of the blade seat 9. The limiting plate 13 has a rectangular plate structure. A limiting spring 14 is fixed between the end of the limiting plate 13 that extends into the limiting plate mounting groove 12 and the inner wall of the limiting plate mounting groove 12. A lever window 15 is opened at the top of the sleeve 2. The lever window 15 is in communication with the limiting plate mounting groove 12. A lever 16 is movably connected in the lever window 15. One end of the lever 16 extends into the limiting plate mounting groove 12 and is fixed to the limiting plate 13. The other end of the lever 16 extends out from the limiting plate mounting groove 12.

When it is necessary to remove the blade seat 9 from the blade seat insertion slot 8, the lever 16 is moved, causing the lever 16 to slide in the lever window 15. The lever 16 drives the limiting plate 13 to move, and the limiting plate 13 exits from the blade seat insertion slot 8 and retracts completely into the limiting plate mounting slot 12, so that the blade seat 9 can be removed from the blade seat insertion slot 8. At this time, the limiting spring 14 is in a compressed state. After the blade seat 9 is inserted into the blade seat insertion slot 8, simply release the lever 16, and the limiting spring 14 can push one end of the limiting plate 13 back into the blade seat insertion slot 8.

[0026] In actual use, the fixed shaft 1 and the sleeve 2 are installed through the threaded connection between the screw hole 3 and the screw 4. A washer 5 is placed on the screw 4 to prevent loosening and to prevent the sleeve 2 from falling off the fixed shaft 1. Simultaneously, a keyway 6 is opened on the inner wall of both the fixed shaft 1 and the sleeve 2. The keyway 6 and the flat key 7 provide circumferential positioning of the sleeve 2. The blade seat 9 is inserted into the blade seat insertion groove 8 opened on the surface of the sleeve 2, thus achieving the movable installation of the blade 10 and the sleeve 2. After use, this anti-clogging yarn suction device can be cleaned by unscrewing the screw 4 from the screw hole 3 and then removing the sleeve 2 from the fixed shaft 1 to easily remove the fine yarn from the brush bristles 11 and restore their adhesion. When the brush bristles 11 on the surface of a certain group of blades 10 are severely worn, the blade seat 9 fixed to the surface of that group of blades 10 can be pulled out from the blade seat insertion groove 8. The blades 10 are then replaced. When the blade seat 9 is inserted into the blade seat insertion slot 8, one end of the limiting plate 13 is inserted into the limiting plate mounting slot 12, and the other end of the limiting plate 13 is inserted into the blade seat insertion slot 8 and abuts against the top of the blade seat 9, thus making the installation of the blade seat 9 in the blade seat insertion slot 8 more secure. When it is necessary to remove the blade seat 9 from the blade seat insertion slot 8, the lever 16 is moved, causing the lever 16 to slide in the lever window 15. The lever 16 drives the limiting plate 13 to move, and the limiting plate 13 exits from the blade seat insertion slot 8 and retracts completely into the limiting plate mounting slot 12, so that the blade seat 9 can be removed from the blade seat insertion slot 8. At this time, the limiting spring 14 is in a compressed state. After the blade seat 9 is inserted into the blade seat insertion slot 8, simply release the lever 16, and the limiting spring 14 can push one end of the limiting plate 13 back into the blade seat insertion slot 8.
