Furthermore, a traction spring is connected between the triangular support leg and the side wall of the bottom of the central shaft tube.

Furthermore, a plurality of anti-skid protrusions are arranged on the bottom surfaces of the supporting feet, and the anti-skid protrusions are of raised ridge-shaped structures.

Beneficial effects of the utility model

The utility model provides a prevent blowing down bicycle can make the focus of bicycle shift to the well rear portion of automobile body through the lateral wall at central siphon bottom install the regular triangle car additional and prop, according to triangle-shaped's steadiness principle, makes the automobile body still can guarantee the steadiness of parking under the wind-blowing that receives any direction or other exogenic actions.

Furthermore, a traction spring is connected between the triangular support leg and the side wall of the bottom of the central shaft tube, so that the triangular support leg is not dragged to the ground during riding of the bicycle.

Further, be provided with a plurality of non-slip raised on the spike bottom surface, non-slip raised is bellied stupefied type structure, has further guaranteed the bicycle parking state under, the performance of grabbing of triangle-shaped kickstand leg.
