In actual use, when the adjustment knob assembly is rotated counterclockwise, the elastic force of the spring is released, and the second folding joint and the first folding joint can be rotated. At this time, the steering handle assembly can be rotated following the second folding joint, and then the steering handle assembly can be folded relative to the first folding joint. When normal use is required, it is only necessary to straighten the steering handle assembly to the normal position, and then rotate the adjustment knob assembly clockwise so that the spring presses the second folding joint and the first folding joint. At this time, the second folding joint and the first folding joint cannot rotate, and the steering handle assembly cannot rotate relative to the bottom connecting sleeve. At this time, the elderly scooter cannot be folded and can be used normally. The folding and normal use operations are very convenient, which greatly improves the convenience of using the elderly scooter. BRIEF DESCRIPTION OF THE DRAWINGS
