The optical degrees of freedom are provided, and an optical scale 25 can be respectively disposed on the X-axis sliding members 20A, 21A, 30A, and 31A and the Y-axis sliding members 20B, 21B, 30B, and 31B to clearly and clearly know the first The displacement positions of the first, second, third, and fourth displacement elements 20, 21, 30, and 31, and the four drilling axes 40 are respectively fixed to the first, second, third, and fourth displacement elements 20, 21, 30, and 31. The Y-axis slide members 20B, 21B, 30B, and 31B are disposed, and the four-drill shafts 40 are respectively provided with a drill 41.

The four-drilled shaft 40 may be disposed on a side of the four Y-axis sliding members 20B, 21B, 30B, and 31B adjacent to the central through-hole 11, as shown in FIG. 1B, according to which the four-drilled shaft 40 is They can be brought together to the greatest extent to meet the drilling requirements of small-sized workpieces, and the four-drilled shaft 40 can be quickly moved to a desired position by the aid of the optical scale 25 to meet the needs of use.
