The side brackets include rear wheel brackets and push-down handles. The structure is essentially: the lower end of the push-down handle and the front wheel The rear end of the bracket is rotatably connected, the front wheel bracket is slidably provided with a sliding sleeve, the upper end of the rear wheel bracket is rotatably connected with the sliding sleeve, and the side bracket also includes an upper link, a lower link, and a rear link of the upper link. The end is rotatably connected with the push-down lever, the front end of the upper link is rotatably connected with the sliding sleeve, the upper end of the lower link is rotatably connected with the connecting seat, and the lower end of the lower link is rotatably connected with the rear wheel bracket , after being folded, the front wheels arranged at the front end of the front wheel bracket are far away from the rear wheels arranged at the lower end of the rear wheel bracket, both the front wheels and the rear wheels touch the ground and cannot be self-supporting, and the The push handle bar is turned forward, and the upper end of the push handle bar is close to the front wheel.
