Technical Field

[0001] The invention relates to the technical field of non-motor vehicle control, in particular to a quick-release brake handle. Background Art

[0002] Braking, also known as braking, refers to the action of stopping or reducing the speed of non-motor vehicles, vehicles and other means of transportation or machinery in operation. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, install a brake shoe, belt or disc corresponding to it on the machine base, and generate a braking torque under the action of external force. The brake device is a mechanical brake device that can slow down the speed of the vehicle, also known as a reducer. Another common bicycle brake is that it is slowed down by a rod-shaped brake fixed on the frame or a disc-mounted brake. The brake handle is an important control component of the brake device. It is generally used in light vehicles, such as electric vehicles. The current brake handle installation method on the market is limited and fixed, and it is very inconvenient to load and unload, which makes the later maintenance difficult and costly.
