[0002] Each carriage of the railway vehicle is connected by a connecting piece composed of a knuckle head, a knuckle tongue and a knuckle pin. The hook cavity and the hook cavity are equipped with hook lock iron, knuckle push iron and other components. When performing maintenance operations on the hook lock iron, knuckle push iron and other components, due to environmental factors, only the knuckle pin can be taken out. Take out the knuckle weighing about 35kg from the hook head and land it on the ground, and then take out the hook lock iron, knuckle push iron and other accessories for maintenance and replacement. This operation is time-consuming and laborious, and there is a safety hazard for the maintenance personnel to be injured by the knuckle , which brings certain troubles to the maintenance operation of railway vehicles
