Its upper end is connected to the handlebar component, the frame component cooperates with the front tube, and the lower end cooperates with the front axle component to form the guide system of the electric vehicle.

[0003] When welding the front fork of an electric vehicle, the front fork is generally clamped in a mold for welding.
