[0019] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] Embodiment one, in Figure 1 Small driving device, including driving device body 1, the outside of driving device body 1 is provided with connecting line 2, the outside of connecting line 2 is provided with winding structure 3, the outside of winding structure 3 is provided with cleaning structure 4, the outside of connecting line 2 is provided with plug 5.

[0021] Connecting line 2 realizes the transmission of electric signal for driving device body 1, usually the length of connecting line 2 is fixed, and connecting line 2 is mostly exposed to air, when connecting line 2 is long, the length of connecting line 2 can be contracted and the surface of connecting line 2 can be protected by winding box 301.

[0022] Embodiment two, in Figure 2 Connecting line 2 is provided with winding box 301 outside, the inside of winding box 301 is rotatably provided with rotating rod 302, the inside of winding box 301 is fixedly provided with partition plate 303, the outside of rotating rod 302 is fixedly provided with reel 304, the outside of rotating rod 302 is fixedly provided with first gear 305, the outside of first gear 305 is engaged with second gear 306, the outside of second gear 306 is fixedly provided with handle 307.

[0023] Manually rotating handle 307, through the engagement of second gear 306 and first gear 305, rotating rod 302 is driven to rotate, through the rotation of reel 304, the two ends of connecting line 2 on the surface of reel 304 are simultaneously wound and unwound, the purpose of zooming connecting line 2 is achieved, so that the length of connecting line 2 is adjusted.

[0024] Embodiment three, in Figure 3 The outside of winding box 301 is fixedly provided with cleaning box 401, the inside of cleaning box 401 is fixedly provided with limiting box 402, the inside of limiting box 402 is fixedly provided with spring 403, the inside of limiting box 402 is movably provided with extrusion block 404, the outside of extrusion block 404 is fixedly provided with cleaning brush 405.

[0025] When the two ends of the connecting line 2 are reeled in and out, they pass through the cleaning box 401, and the cleaning brush 405 is in close contact with the surface of the connecting line 2, so that the surface of the connecting line 2 can be cleaned by the cleaning brush 405 when the connecting line 2 is moved, so that the outside of the connecting line 2 is always kept clean.

[0026] In summary, the small driving device winds the connecting line 2 outside the reel 304, and when the connecting line 2 needs to be reeled in and out, rotating the handle 307 can drive the rotation of the rotating rod 302, so that the two ends of the connecting line 2 are reeled in and out at the same time, which is convenient for adjusting the length of the connecting line 2 and preventing the connecting line 2 from being wound, thereby increasing the service life of the connecting line 2.
