In order to solve the above problems, the folding device 10 for the folding scooter comprises limit screws 10k fixedly installed on both sides of a frame base or a frame back, and rubber rings or rubber sleeves sleeved on the outer sides of the limit screws 10k, wherein at least one limit screw 10k is arranged below each safety belt connecting plate 10 a.

The damping through the rubber ring or the rubber sleeve can avoid rigid butt, has solved the wearing and tearing of safety belt connecting plate 10a, has the problem that factor of safety reduces to and the too big problem that influences the use comfort of noise.

In a further embodiment, the folding device 10 for the folding scooter comprises a limiting shell 10b sleeved on the outer side of the safety belt connecting plate 10a, the limiting shell 10b is fixedly connected with the frame base or the frame back, at least one limiting groove is formed in the side face of the limiting shell, and the rotating connection part of the safety belt connecting plate 10a and the frame base or the frame back is accommodated in the limiting groove.

The safety belt connecting plate 10a is limited through the limiting shell 10b, so that the problem that the position of the safety belt cannot be found quickly when the safety belt is needed due to overlarge rotation amplitude of the safety belt connecting plate 10a is solved. In a further embodiment, a rubber pad is fixedly mounted on the side wall of the limit groove of the folding device 10 for the scooter.

As described above, although the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limiting the invention itself. Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
