description The utility model discloses a jack jaw for a vehicle, which relates to the technical field of jacks and comprises a lifting component and a jaw component, the jaw component can drive the lifting component to lift and comprises a second hydraulic cylinder, a second piston rod is slidably connected into the second hydraulic cylinder, and two fixing rings are fixedly connected to the surface of the second hydraulic cylinder. The portion, located in the middle of the fixing ring, of the surface of the second hydraulic cylinder is movably sleeved with a movable cylinder, arc-shaped grooves are formed in the opposite sides of the fixing ring and the movable cylinder, balls are movably connected into the arc-shaped grooves, and the two sides of the balls abut against the inner walls of the arc-shaped grooves. As the gap exists between the fixed ring and the movable cylinder, the movable cylinder shakes up and down, and meanwhile, the friction force between the fixed ring and the movable cylinder can be reduced by ar
