[0023] like Figure 1-2 As shown, in this embodiment, a new type of brake handle is provided, including a handle cover 1 and a visual oil tank 2. A liquid injection chamber 3 is provided inside the handle cover 1, and a piston pressure plate 8 is slidably provided inside the liquid injection chamber 3. The push rod 5 abuts against the piston pressure plate 8. The push rod 5 is moved by the user to control the handle 7. When the push rod 5 moves, the piston pressure plate 8 is moved, and then the hydraulic oil inside the liquid injection chamber 3 enters the oil pipe to enable the final hydraulic actuator to clamp the wheel to achieve the braking effect. Specifically, an oil hole is provided on one side of the handle cover 1. The oil hole passes through the handle cover 1 and is connected to the liquid injection chamber 3. The oil hole is used to connect to the oil pipe, and the oil pipe is connected to the liquid injection chamber 3 through this oil hole. It is worth mentioning that the handle 7 is rotatably connected to the handle cover 1 through a torsion spring shaft to facilitate the resetting of the handle 7.

The buffer shaft 6 is provided because the push rod 5 controls the piston pressure plate 8 in a linear motion, while the handle is rotary. Therefore, a buffer shaft 6 is needed to transition the angle change between the handle 7 and the push rod 5, and to convert the swing of the handle 7 into pressure to press the piston pressure plate 8. Furthermore, in order to minimize the friction between the push rod 5 and the piston pressure plate 8, the end of the push rod 5 that abuts the piston pressure plate 8 is set in a spherical shape. The handle 7 is embedded with a rotating sleeve 9, and the buffer shaft 6 passes through the rotating sleeve 9 and is rotatably connected to the handle 7. This rotating sleeve 9 allows the buffer shaft 6 to rotate freely on the handle 7.

[0025] The handlebar cover 1 is also provided with an electrical control chamber 4 for accommodating the power disconnect switch. The handlebar cover 1 is provided with an opening.
