A groove 16 adapted to the slider 15 is opened on the inner wall of the rectangular box 7. The movement of the rack 13 is limited by the cooperation of the slider 15 and the groove 16, which prevents the rack 13 from shaking during movement and thus improves the stability of the rack 13 during movement. A hook is fixedly connected to one side of the strap roll 2.

[0025] Working principle: When using this utility model, the user rotates the threaded rod 9 to move the rack 13, which in turn drives the gear 10 to rotate. Under the guidance of the connecting rod 11, the gear 10 drives the pressure plate 12 to move. Then, the pressure plate 12 drives the brush plate 17 to fit against the surface of the strap roll 2. After that, the ratchet locking assembly 3 is pressed to unlock it. Then, the crank handle 4 is turned to drive the strap roll 2 to rewind. During this process, the brush plate 17 wipes the strap roll 2 when it is rewinding. Then, the ratchet locking assembly 3 is released to reset it and lock the rotation state of the strap roll 2 in one direction. This realizes that the surface of the strap is wiped when it is tightened, so that the dirt attached to the surface of the strap can be cleaned and removed, thereby improving the cleanliness of the strap surface and making it easier to reuse.

[0026] In summary, this cargo strap fastener works by rotating the threaded rod 9 to move the rack 13, which in turn drives the gear 10 to rotate. Under the guidance of the connecting rod 11, the gear 10 drives the pressure plate 12 to move. The pressure plate 12 then drives the brush plate 17 to come into contact with the surface of the strap roll 2, allowing the brush plate 17 to wipe the strap roll 2 during winding. This achieves the goal of wiping the surface of the strap when it is tightened, cleaning and removing dirt adhering to the surface of the strap, thereby improving the cleanliness of the strap surface and facilitating reuse.
