Through the cooperation between the guide columns 17 and the sliding grooves 16, the sliding columns 14 are guided to prevent the sliding columns 14 from shifting during the movement and affecting the positioning effect.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, two transverse slides 2 are fixedly connected to the upper end of the calibration workbench 1, and the inner walls of the transverse slides 2 are slidably connected to the longitudinal sliding frames 3.
