Gear 12, a bevel gear 13 is provided on one side of gear 12, teeth are provided on one side of gear 12 to mesh with bevel gear 13, a second gear 14 is provided on the top of bevel gear 13, a toothed plate 15 is provided on one side of gear 14 to mesh with, a fixed plate 16 is fixed on the top of toothed plate 15, a first tooth groove 31 is provided at one end of fixed plate 16, a third gear 29 is provided at one end of first tooth groove 31 to mesh with, a pull ring 30 is rotatably connected to the top of third gear 29, first groove 3 is slidably connected to fixed plate 16, and third sliders 17 are fixed at both ends of the top of fixed plate 16. Third sliding grooves 18 are provided on the top and bottom of one side of the main body 1, and third sliding grooves 18 are slidably connected to third sliders 17.

[0027] By pushing the plug 4 into the fixed box 22, the plug 4 retracts. The plug 4 slides through the first slider 7 and the first groove 10. The sliding of the first slider 7 drives the first gear 12, which drives the meshing bevel gear 13. The bevel gear 13 drives the second gear 14, which drives the meshing toothed plate 15 to move to the left. The toothed plate 15 drives the fixed plate 16, which slides through the third slider 17 and the third groove 18. The fixed plate 16 moves to the left and engages with the first groove 3, fixing the data cable 21 in the groove 2. The cylinder 28 is pressed to engage with the first round hole 5 to prevent loosening.

[0028] Please refer to this carefully. Figure 1-5The main body 1 has a groove 2 in the middle, and a slide plate 2 is set inside the groove 2. The top of one end of the slide plate 2 has a second tooth groove 33. The inner walls of the top and bottom of the groove 2 are both set with a first groove 3. The other end of the main body 1 has a USB interface 24. The two sides of the USB interface 24 are rotatably connected to the shafts 25. The end of the shafts 25 is set inside the groove 2. A conductive block 19 is set on one side of the plug 4. A circuit board 20 is set on one side of the fixed box 22. A fourth slide groove 26 is set at one end of one side of the circuit board 20. The fourth slide groove 26 is slidably connected to the conductive block 19. A conductive plate 27 is set inside the fourth slide groove 26. A cylinder 28 is set on one side of the top of the main body 1. The middle of the cylinder 28 passes through the third round hole 23. A data cable 21 is set inside the USB interface 24. The second tooth groove 33 meshes with one end of the third gear 29.

[0029] The data cable 21 is wound into the groove 2 by rotating the USB interface 24 upward through the pivot 25. The plug 4 drives the conductive block 19, which slides towards the conductive plate 27 through the fourth slide groove 26, so that the conductive block 19 is connected to the conductive plate 27.

[0030] Working principle: Rotating the USB interface 24 causes it to rotate upwards via the pivot 25, evenly winding the data cable 21 into the groove 2. This pushes the plug 4 into the fixed housing 22, causing it to retract. The plug 4 slides along the first slider 7 and the first slide groove 10. The sliding of the first slider 7 drives the first gear 12, which in turn drives the meshing bevel gear 13. The bevel gear 13 drives the second gear 14, which in turn drives the meshing toothed plate 15 to move to the left. The toothed plate 15 then moves the fixed plate... 16. The fixing plate 16 slides through the third slider 17 and the third slide groove 18. The fixing plate 16 moves to the left and engages with the first groove 3 to fix the data cable 21 in the groove 2. Pressing the cylinder 28 makes it engage with the first round hole 5 to prevent loosening and facilitate carrying. When in use, pull the cylinder 28 to move it out of the first round hole 5 and pull out the plug 4. The plug 4 drives the second slider 9 to slide. The second slider 9 should be slidably connected with the second slide groove 11 to prevent the plug 4 from sliding out of the fixing box 2 when it is pulled again. 2. Plug 4 drives conductive block 19, which slides along the fourth groove 26 towards conductive plate 27, connecting it to the conductive plate 27. Plug 4 drives slider 7, which in turn drives toothed groove 8. Toothed groove 8 drives gear 12, which in turn drives bevel gear 13. Bevel gear 13 drives gear 14, which in turn drives gear plate 15. Gear plate 15 pulls fixed plate 16, causing it to leave groove 3 and return to its original position, thus opening groove 2 to remove data cable 21. Then, the fixed plate 16 is pulled... Press the pull ring 30 in front of the fixed plate 16. The pull ring 30 pushes the third gear 29. The third gear 29 meshes with the first tooth groove 31 and the second tooth groove 33, pushing the main body 1 inward to both sides. The main body 1 slides inward through the sliding plate 32 to reduce its volume. When the sliding plate 32 slides inward, it drives the third gear 29 to rotate. The third gear 29 drives the fixed plate 16 to slide to one side through the first tooth groove 31. The fixed plate 16 drives the plug 4 to slide outward through the toothed plate 15. Press the cylinder 28 to fix the cylinder 28 into the second round hole 6 for easy use.
