The outer wall of the cylinder 5 can be clamped and pressed together by the three-claw chuck on the lathe. When a through hole is required to be opened on the upper part of the outer wall of the workpiece 1, the workpiece 1 is placed between the clamping plate 3 and the plate 2, and the bolt 4 is rotated clockwise to penetrate the clamping plate 3 and is threadedly connected to the plate 2, so that the clamping plate 3 and the workpiece 2 can be pressed together. At this time, the cylinder 5 is pressed together with the outside of the lathe. The three-jaw chuck is docked, and then the lathe is started to rotate the three-jaw chuck. During this process, the cylinder 5, the through hole 6 and the center point of the opening on the outer wall of the workpiece 1 will all rotate concentrically with the three-jaw chuck. Then, the tail stock on the lathe is controlled so that the drill bit installed at the end of the tail stock is in contact with the workpiece 1 in the rotating process, and the lathe can realize the hole opening operation on the outer wall of the shaft workpiece 1.
