For example, the x-axis moving mechanism 810 is provided with an x-axis adjusting rotating handle 811 for manually adjusting the moving distance of the x-axis moving mechanism 810 on the y-axis moving mechanism 820 along the x-axis. Rotating the x-axis adjusting rotating handle clockwise or counterclockwise can make the x-axis moving mechanism 810 move right or left on the y-axis moving mechanism 820 along the x-axis. Similarly, the y-axis moving mechanism 820 is provided with a y-axis adjusting rotating handle 821, and the z-axis moving mechanism 830 is provided with a z-axis adjusting rotating handle 831.
