[0031] By arranging a plurality of uniformly distributed reaming tooth rings 304 on the surface of the reaming head 303, the reaming tooth rings 304 can be used to chisel and process preformed screw holes of different hole diameters.

[0032] It should be noted that the end of the reaming head 303 is provided with three air injection holes 308, the air injection holes 308 are in a strip structure, and the three air injection holes 308 are uniformly distributed in a triangular array on the end of the reaming head 303.
