[0018] like Figure 2 , 3 As shown, in order to further optimize the structure of the steering column clamp and ensure that the fixing structure will not loosen and cause axial movement during subsequent transportation, the steering column clamp 2 includes an upper connecting plate 22 and a steering column connecting groove tube 23, and the steering column connecting groove tube 23 is arranged at the bottom of the upper connecting plate 22. The steering column connecting groove tube 23 has a bolt connection portion 24 that is connected to it as a whole and is symmetrically arranged. The steering column connecting groove tube 23 is sleeved on the steering column 1, and the handlebar bolt 3 passes through the bolt connection portion 24 and fixes the steering column 1 to the steering column clamp 2 through a U-shaped nut.

[0019] like Figure 3 As shown, in order to increase the contact area between the steering column and the steering column clamp and improve the locking effect, the steering column connecting groove 23 includes a back plate 231 fixedly connected to the bottom of the upper connecting plate 22, and side plates 232 arranged on both sides of the back plate 231 and vertically connected thereto. The steering column 1 is inserted into the steering column slot 21 composed of the back plate 231 and the two side plates 232, and each side plate 232 is provided with a bolt connection part 24 integrally connected thereto.
