[0048] When installing and using the tool, the other end of the tool rod 1 can be clamped on a tool holder of a lathe, milling machine, CNC or other machine tools.

[0049] Specifically, the blade 2 has a top edge 21 and a bottom edge 22; the top edge 21 is located at the upper end of the blade 2 in the vertical direction and is in a vertical state, and is mainly responsible for cutting and scraping. During the processing, the top edge contacts the workpiece and cuts off the material to form the desired shape or contour; the bottom edge 22 is located at the lower end of the blade 2 in the vertical direction and is in an inclined state, and is mainly used for supporting and stabilizing, so that the blade remains stable during the cutting process and prevents vibration and deviation.

[0050] Based on the above embodiment, one end of the knife bar 1 is provided with a mounting table 11 and a pressing table 12, the mounting table 11 is lower than the pressing table 12, and the arc groove 13 is provided on the mounting table 11.
