The rear axle capture manipulator comprises a center shaft, a mechanical arm, an arm rod lantern ring, a transverse rod lantern ring and a hinge head. The mechanical arm is composed of a first arm rod, a bearing transverse rod, a second arm rod, a claw and a claw lantern ring; the top of the first arm rod is connected with the arm rod lantern ring, and the bottom of the first arm rod is connected with the claw lantern ring; one end of the bearing transverse rod is connected with the middle of the first arm rod, and the other end of the bearing transverse rod is connected with the transverse rod lantern ring; the bottom of the center shaft is connected with the second arm rod through the hinge head, and the top of the center shaft sequentially penetrates through the transverse rod lantern ring and the arm rod lantern ring; the claw penetrates through the claw lantern ring to be connected with the second arm rod through a claw rotor. When the manipulator falls to be located at the position above a rear axle, the center shaft drops to drive the second arm rod to drop, and the claw is pushed to outwards move along the claw lantern ring so as to be opened. When the manipulator rises, the center shaft rises to drive the inner end of the second arm rod to upwards move, and the claw is pulled to inwards move along the claw lantern ring so as to capture the rear axle of a car.
