A U-shaped lower end groove 4D is engraved.

A lower scale 6 is attached to the front surface of the upper frame 3C of the gantry 3, and an upper scale 7 corresponding to the lower scale is also attached to the front surface of the receiving frame 4. A lock handle 8 for screwing the protrusion 4B of the receiving frame 4 from the outside is screwed to the upper frame 3C of the frame 3.

Reference numeral 9 denotes a drill guide arm, which includes a rear plate portion 9A attached to the rear portion of the gantry 3 so as to be vertically adjustable, and a horizontal plate portion continuously connected to the upper end of the rear plate portion toward the front. 9B and a drill guide bush 9C arranged on the horizontal plate portion. The center of the drill guide bush 9C is configured to coincide with the center line of the lower end groove 4D of the receiving frame 4.

The elevating structure of the back plate portion 9A with respect to the pedestal 3 includes a vertical groove 9A1 engraved in the back plate portion and a bolt 9A2 that is tightened from the outside to the pedestal by using the vertical groove. It is configured. 9C1 and 9C2 are tightening bolts for the pin 5, and 9C3 is a tightening bolt for the drill guide bush 9C.
