The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model shown in fig. 1-4 comprises a cylindrical cutter body 1 and a cylindrical clamping rod 2, specifically, the clamping rod 2 is mounted on the top end of the cutter body 1, and optionally, the clamping rod 2 can also be integrally formed with the cutter body 1. In a practical implementation, the diameter of the part of the clamping bar 2 is smaller than the diameter of the part of the tool body 1, and the tool body 1 needs to extend into the guide hole 61 of the housing type product 6, because the size of the tool body 1 is determined according to the size of the guide hole 61 of the housing type product 6. The outer surface of the cutter body 1 is provided with a positioning chute 11 in the vertical direction (the direction indicated by the arrow in fig. 1 is the vertical direction), and the bottom end of the cutter body 1 is provided with a reverse cutting edge 4.
