[0002] In the drilling tool with replaceable cutter head, during the drilling process, due to the large radial and axial forces on the cutter head, the axial displacement of the cutter head at the joint will cause the drilling to be imprecise, such as The Chinese patent application number is 201210152756.9, which discloses a rotatable drilling tool and a substrate for the rotatable drilling tool. The drill can replace the cutter head, and the cutter head and the substrate are fixed by inserting the convex part into the concave part. The connection surface between the cutter head and the base body is close to the level. Due to the large axial force during the drilling process, the position of the cutter head will be offset and the drilling will not be fine. Some structures are also set in the prior art. Compact structure, but its replacement process is too complicated
