[0031] When the chassis 2 drives the first bearing seat 4 and the target rotating assembly 3 to move, the first bearing seat 4 slides with the linear guide rail 5, ensuring the stability of the target rotating assembly 3 in the horizontal direction. The target rotating assembly 3 drives the gravity rod 7 to move. During the process of the target rotating assembly 3 moving inward (200 mm), the gravity rod 7 is blocked by the gear lever 6 from rotating, so that the target rotating assembly 3 rotates synchronously. When the target rotating assembly 3 is reset to the outside, under the action of the gravity rod 7, the gravity rod 7 and the target rotating assembly 3 automatically reset and rotate, which is convenient for the recycling of the equipment and accurately simulates the effect of the tire rotation of the car moving forward and backward, thereby eliminating the adverse effects caused by the large elasticity of the car chassis and the inability of the car to solidify and avoid, and facilitating the equipment to test the four-wheel alignment instrument;
