A tapered hole with a release chuck installed therein is provided vertically, a rotary cylinder capable of controlling the rotation angle is provided around the support cylinder of the rotary shaft, and a support base on which a plurality of tool units are mounted is further provided on the machine base. Each tool unit has, on the top surface of the gearbox, a protrusion that fits into the insertion hole provided in the rotating cylinder and a tapered protrusion that fits into the tapered hole of the rotating shaft, and the tapered protrusion is inserted through the gearbox. The support base is rotatably connected to a horizontal rotation shaft on which a tool is mounted, and the support base is provided with a feeding mechanism for fitting the tapered protrusion of each tool unit into the tapered hole of the rotation shaft.
