Specifically, the backrest 32 and the seat are fixed through the driving screws, so that the backrest 32 can rotate by taking the screws as rotating shafts, and a waveform elastic sheet and a nylon top block are further installed between the backrest 32 shell and the seat shell to form rotary friction resistance, so that the rotation angle of the backrest 32 is adjustable. As shown in fig. 1 and 2, the backrest 32 can form an unfolding angle of about 90 degrees with the seat when the backrest 32 is in the first state, and the backrest 32 is parallel with the base 31 when the backrest 32 is in the second state.

In addition, a second holding portion 311 is provided at the front end of the base 31, as shown in fig. 2, when the folding frame is in a folded state, the second holding portion 311 can be closely matched with the first holding portion 81 for holding by the hand, so that the convenience of movement of the scooter is improved.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
