A self-adjusting supporting head comprises a vehicle body lifting column (10) and a load-bearing detection device arranged on the vehicle body lifting column (10). The load-bearing detection device comprises a spring supporting plate (5), a spring (6), a limiting switch tip (8), a load limiting switch (9) and a floating load-bearing adjusting device. The floating load-bearing adjusting device comprises a floating load-bearing block (1), a floating load-bearing block mounting base (2) and a floating connector. The floating load-bearing block is in spherical fit with the floating load-bearing block mounting base. The floating load-bearing block can swing in random directions above the floating load-bearing block mounting base according to the specific state of a steel plate in contact with the floating load-bearing block. When the heights of a plurality of steel plates welded on the side beam of a vehicle are not inconsistent, the floating load-bearing block can automatically correct according to the steel plates through a spherical fit structure, so as to realize that the upper surface of the floating load-bearing block is in complete contact with the steel plates, and ensure that the side beam of the vehicle is uniformly stressed and the vehicle is not damaged.
