The invention discloses a chassis apparatus capable of eccentrically arranging a survey marker. The chassis apparatus comprises a lower disc, an upper disc, three support bars and a connecting rod, wherein the lower disc is in a Y shape, and comprises a disc main body provided with a center aperture and three blade parts uniformly distributed around a disc main body, a loop of angle graduation lines is arranged by winding the center aperture on the disc main body, the upper disc is the disc provided with a cross-shaped chute, the center of the cross-shaped chute is the center of the upper disc, a slide block sliding along the cross-shaped chute is arranged in the cross-shaped chute, a displacement graduation line is arranged around the cross-shaped chute, three support bars are used for respectively connecting with three blade parts and the upper disc, the leveling of the upper disc is realized by adjusting three support bars, and the connecting rod passes through the slide block and is fixed on the slide block. The chassis apparatus has the functions of accurate leveling and accurate centering, increases the eccentric angle and eccentric distance precision, and has the advantage of simple operation.
