Wherein, the position of involute type alignment post 5 on holding surface 10 sets up to rotatable regulation, because involute locating surface 50 is the involute cambered surface, when rotating adjustment involute type alignment post 5, it can promote solid of revolution component 6 towards two cylinder alignment posts 4 to adjust solid of revolution component 6's cylinder benchmark through three-cylinder centering principle. In an embodiment different from the illustrated embodiment, the involute locating surface 50 of the involute barrel 5 may be the outer peripheral surface of a cam.
Three tilt columns 2 are arranged upright on a support surface 10 and are configured for leveling a supported body element 6. Fig. 3 shows a perspective view of the tilt column 2, and fig. 4 shows a cross-sectional view of the tilt column 2. As shown, the tilt column 2 includes a frame body 20, a driving block 21, a contraction block 22, and an adjustment bolt 24. Wherein a slide passage 200 is provided inside the housing body 20, and the driving block 21 is guided to be reciprocally slidable in the slide passage 200.
