Specifically, the centering pin 14 is welded at one end of the second centering piece 13, the centering pin 14 may specifically be a bolt, and the first centering piece 12 is rotatably sleeved on the centering pin 14 to realize rotatable connection between the first centering piece 12 and the second centering piece 13, and in addition, the first centering piece 12 and the second centering piece 13 may be respectively connected to corresponding positioning rods through bolts.
When the two positioning rods clamp or abut against the wheel body along the reference wheel body serving as the reference, the positioning rods are parallel to the center line of the wheel groove of the wheel body, and the center line of the wheel groove of the wheel body is specifically perpendicular to the axial direction of the wheel body. The diagonal A of the included angle formed by the first centering piece 12 and the second centering piece 13 is parallel to the positioning rods, and the distance between the diagonal A and the two positioning rods is equal, so that the center line of the wheel groove of the wheel body is coplanar with the diagonal A correspondingly, the axial lead of the centering pin 14 is also coplanar with the diagonal A, on the basis, after the walking adjustment tool 1 is installed on the two reference wheel bodies, a straight line can be determined through the centering pins 14 on the two walking adjustment tools 1, and the straight line is compared with the center line of the wheel groove of the wheel body to be positioned, so that the center lines of the wheel grooves of all the wheel bodies can be adjusted to be coplanar.
