In the figure, the X-axis and the Y-axis are perpendicular on the same horizontal plane, and the Z-axis is perpendicular to the X-axis and the Y-axis respectively.
[0023] It should be noted that the first X-axis fine-tuning bolt and the second X-axis fine-tuning bolt can be used to adjust the inclination angle of the calibration bracket 10 in the vertical direction so that the line connecting the calibration point a and the calibration point b is parallel to the X-axis direction, and the first Y-axis fine-tuning bolt and the second Y-axis fine-tuning bolt can be used to adjust the inclination angle of the calibration plate 20 in the horizontal direction so that the line connecting the calibration point a and the calibration point c is parallel to the Y-axis direction, ensuring that the metal block 30 used for calibration is level.
