[0041] Working principle: First, the user places the scooter body 1 in a suitable position. Then, when the user needs to replace the pulley body 305, the user first observes the current state of the scooter to ensure that it is in a safe and stable environment. After that, the user forcibly pulls the pulley body 305 to be replaced in the direction away from the fixed rod 205. Since the magnet 303 is adsorbed in the adsorption groove 307, it is necessary to overcome the adsorption force of the magnet 303 at this time. As the pulling force increases, the pulley body 305 gradually separates from the connecting rod 302, and the limiting effect of the clamping ring 304 on the pulley body 305 also disappears. In the process of the pulley body 305 being separated, the friction between the rubber gasket 4 and the magnet 303 gradually decreases until they are completely separated. Then, when the old pulley body 305 is removed, the user is ready to install a new pulley body 305 and put the new pulley The engaging groove 306 of the body 305 is aligned with the connecting rod 302, and the user gently pushes the pulley body 305 to engage with both sides of the connecting rod 302. During the engaging process, the engaging ring 304 plays a guiding and limiting role, ensuring that the pulley body 305 is accurately installed in the correct position. As the pulley body 305 approaches, the adsorption groove 307 gradually approaches the magnet 303. When the distance is close enough, the adsorption force of the magnet 303 begins to play a role, and the pulley body 305 is tightly adsorbed on the fixing ring 301. At this time, the rubber gasket 4 again increases the friction between the adsorption groove 307 and the magnet 303, making the adsorption more firm. Finally, the user checks the installation of the pulley body 305 to ensure that it is firm and reliable. If multiple pulley bodies 305 need to be replaced, the above steps can be repeated until all pulleys are replaced.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
