BACKGROUND OF THE INVENTION
1. Fields of the invention The present invention relates to a kickstand of a bicycle, and more particularly, to a kickstand that is secured to the chainstay firmly.
2. Descriptions of Related Art The conventional kickstand of a bicycle has a head connected to the bicycle frame such as the chaistay, and includes a leg which is pivotably connected to the head. When parking the bicycle, the leg is kicked downward and contacts the ground, and the leg extends at angle relative to the bicycle so as to support the bicycle. The convdention kickstands are disclosed to Taiwanese Utility Models M290841 and M468466, and CN210555274U of China.
However, the shape of the cross section of the chainstay is round, so that the head of the kickstand has to be curve to as to be mounted to the tube of the chainstay, and two bolts are used to secure the tube of the chainstay to the head of the kickstand. Usually the tube of the chainstay is smooth, and the kickstand is difficult to be properly secured to the tube. In other words, the head of the kickstand eventually will slip or loose relative to the tube of the chainstay by vibration or impact. Therefore, the users have to check the tightness of the bolts to ensure that the kickstand functions as Date Recue/Date Received 2021-08-17 expected. On the contrary, if the bolts are overly tightened, the head of the kickstand may be deformed, and the deformed head cannot hold the tube of the chain stay, or even broken.
The present invention intends to provide a kickstand of a bicycle to eliminate shortcomings mentioned above.
