Base supporting mechanism facilitating height adjustment of production machine tool

The utility model relates to the technical field of production of machine tools, in particular to a base supporting mechanism convenient for height adjustment of a production machine tool, which is used for solving the problems that most existing machine tools are difficult to realize height adjustment, the machine tool cannot be leveled in the height adjustment process, and the manufacturing precision of the machine tool is seriously influenced. Comprising a machine tool body, upper supports, lower supports, height adjusting assemblies and leveling assemblies, the upper supports are installed at the corners of the bottom wall of the machine tool body, the lower supports are movably installed in the upper supports, the side portions of the multiple lower supports are connected with the height adjusting assemblies, and the leveling assemblies are installed among the side portions of the multiple upper supports; according to the machine tool, the height adjusting assembly and the leveling assembly are matched w
