[0002] Electric vehicles, motorcycles and other means of transportation are equipped with brake handles for braking during driving. The brake handle, also known as the brake handle, refers to a device that stops or slows down a running locomotive, vehicle and other means of transportation or machinery. The safety of the brake handle directly affects the life safety of the driver. Electric vehicles are a small and light means of transportation. Because of their light weight and fast acceleration, they are especially popular among office workers. During the riding of an electric vehicle, it is necessary to frequently control the speed by braking.

[0003] The existing electric vehicle brake handle has a connection portion between the brake line and the brake handle, which is prone to bending after long-term use because it is not equipped with a supporting mechanism. As a result, the bending force causes the brake line to fall off, resulting in poor safety in use. Moreover, after long-term use, the brake handle is not easy to quickly reset after braking, and is not flexible enough to use. Therefore, technical personnel in this field provide an electric vehicle brake handle that prevents the brake line from falling off, so as to solve the problems raised in the above-mentioned background technology.
