[0021] In the embodiment two, based on the embodiment one, Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The inner wall of mainframe 1 below leveling seat 201 is provided with notch part 101 for Z-axis lifting of sliding table 8 and longitudinal beam 9, protective shell 5 is installed on the side outer wall of side plate 6 away from mainframe 1, foot support 601 is installed on the other side outer wall of side plate 6 for connecting with the bottom end of support table 3, after completing correction work, the height of sliding table 8, longitudinal beam 9 and sliding type flatness detection structure 10 is controlled by screw lifting module 7, and the setting of notch part 101 provides margin for the lifting of longitudinal beam 9 and sliding type flatness detection structure 10, and does not affect the lifting action of leveling seat 201 in the process;
