[0036] Reference Figure 1 and Figure 5 The cleaning component includes two fixing blocks 11. The outer side of the fixing block 11 is fixedly connected to the outer side of the winding box 1. The inner wall of the fixing block 11 is fixedly connected to a slide rod 12. A spring 14 is sleeved on the outer side of the slide rod 12. The slide rod 12 is slidably connected to a slider 15. A brush 13 is fixedly connected between the two sliders 15.

[0037] Specifically, the fixing block 11 is used to fix and connect to the outside of the winding box 1 and support the slide bar 12; the slide bar 12 is used to provide a sliding track for the slider 15 and fix the second spring 14; the second spring 14 is used to provide elastic force so that the slider 15 drives the brush 13 to fit tightly against the surface of the audio and video cable 2; the slider 15 is used to slide on the slide bar 12 and connect the brush 13; the brush 13 is used to clean the dust and debris on the surface of the audio and video cable 2 during winding and unwinding.

[0038] Reference Figures 1-5 One end of spring 9, away from pawl 8, is fixedly connected to the inner wall of take-up box 1. The outer side of spring 9 is rotatably connected to the inside of one of the partitions 3. One end of spring 6 is fixedly connected to the outer side of take-up bar 4, and the other end of spring 6 is fixedly connected to the outer side of take-up box 1. Pawl 8 is engaged with ratchet 7. One end of spring 14 is fixedly connected to the outer side of fixed block 11, and the other end of fixed block 11 is fixedly connected to the outer side of slider 15. The bristles of brush 13 are made of soft material. The outer side of slider 15 is slidably connected to the inner wall of fixed block 11.

[0039] Specifically, spring 9 provides elastic force to keep pawl 8 engaged with ratchet 7, and its end away from pawl 8 is fixed to the inner wall of take-up box 1 and rotatably connected to the inside of partition 3 to ensure stable operation of pawl 8; spring 6 stores elastic potential energy when the audio / video cable 2 is pulled out and releases it when it is retracted to achieve automatic rewinding, one end of which is fixed to the outside of take-up bar 4 and the other end is fixed to the outside of take-up box 1 to ensure effective transmission of elastic force; pawl 8 engages with ratchet 7 to lock the length of the audio / video cable 2; spring 14 provides elastic force to make slider 15 drive brush 13 to fit tightly against the surface of audio / video cable 2, one end of which is fixed to the outside of fixing block 11 and the other end is fixed to the outside of slider 15 to ensure elastic support; the bristles of brush 13 are made of soft material to avoid scratching the cable when cleaning the surface of audio / video cable 2; the outside of slider 15 is slidably connected to the inner wall of fixing block 11 to ensure its stability when sliding on slider 12.

[0040] Working principle: When the audio / video cable 2 is needed, pulling both ends of the cable causes it to rotate. The cable 2 then rotates the take-up reel 5, which in turn rotates the take-up lever 4. The spring 6, which is sleeved on the outside of the take-up lever 4, deforms and stores elastic potential energy. At the same time, the ratchet 7, which is fixedly connected to the outside of the take-up lever 4, also rotates. Because the pawl 8 engages with the ratchet 7, and the spring 9, which is fixedly connected to the outside of the pawl 8, provides tension, the pawl 8 engages in the tooth groove of the ratchet 7, preventing the ratchet 7 from rotating in the opposite direction. This achieves a fixed extended length for the audio / video cable 2, preventing it from automatically retracting.

[0041] When the audio / video cable 2 needs to be stored after use, rotate the lever 10. The lever 10 drives the pawl 8 to rotate, causing the pawl 8 to separate from the ratchet 7. At this time, under the elastic restoring force of the spring 6, the winding lever 4 drives the cable winding reel 5 to rotate, winding the audio / video cable 2 around the outside of the cable winding reel 5 to complete the winding.

[0042] During the retraction and extension of the audio / video cable 2, the cable will come into contact with the brush 13. Since the slider 15 is slidably connected to the inner wall of the fixed block 11 and sleeved on the outside of the slide rod 12, the spring 14 sleeved on the outside of the slide rod 12 provides elasticity to the slider 15, allowing the brush 13 to fit tightly against the surface of the audio / video cable 2. Thus, when the audio / video cable 2 moves, the brush 13 can clean its surface and remove dust and debris.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
