[0033] Working principle: before using the device, first, the cylinder 4 is driven by the power of the DC motor 3 to rotate smoothly. As the cylinder 4 rotates, the first gear 5 above it also rotates.

At the same time, a buffer frame 202 is introduced to reduce the squeezing force between the two to ensure the stability and safety of the structure. In addition, through the precise cooperation of the card block 204 and the card slot 206, the connection between the top cover plate 7 and the box body 1 is more stable and reliable. In addition, the top cover plate 7 is tightly connected to the box body 1 using the fixing screws 205, which not only enhances the stability of the overall structure, but also effectively prevents external dust and other impurities from entering the interior of the box body 1, thereby further reducing noise and vibration and improving overall practicality.
