Railway wagons typically include a body, a bogie, a brake, a coupler draft gear, and the like. The coupler buffer device is composed of a coupler, a buffer, a coupler yoke, a slave plate and other parts. In the coupler buffer device, the coupler is used for realizing connection between a locomotive and a vehicle or between the vehicle and the vehicle, transmitting traction force and impact force and keeping a certain distance between the vehicles. The end part of the car coupler is provided with a coupler knuckle, and the opening and closing of the coupler knuckle is the opening and closing of the car coupler. The coupler is internally provided with a coupler lock, a push iron, a lower lock pin rod and the like, and the movement of the small piece of the coupler cavity drives the opening or closing of the coupler knuckle.

In a conventional uncoupling lever device, when the coupler knuckle of a coupler needs to be opened, the uncoupling lever needs to be moved upwards, and the uncoupling lever drives the coupler lock in the coupler cavity to move upwards, so that the contact blocking surface of the coupler lock and the coupler knuckle moves to be opened, and the rotation of the coupler knuckle is not limited. The hook lock continues to move upwards, so that the push iron can be driven to rotate, and the push iron rotates to drive the hook tongue to open.
