[0009] First, by fixing three clamping plates on the upper end of the tool handle and setting external threads on the surface of the clamping plates, the milling cutters of different materials and sizes can be easily replaced with nuts to meet the requirements of different key specifications and materials, reduce the difficulty and time cost of replacing the milling cutter by the operator, and improve work efficiency. Secondly, by setting the diameter of the upper half of the through hole to be larger than the diameter of the lower half, and making the diameter of the upper half of the through hole larger than the diameter of the milling cutter, the limiting function of the milling cutter is realized. This design can effectively prevent the milling cutter from offsetting or sliding during the milling process, ensuring the accuracy and stability of the milling. At the same time, the limiting function can also reduce the problem of poor contact between the milling cutter and the key material, avoid processing defects and tool wear caused by poor contact, and in addition, the milling cutter device of this case also has the advantages of simple structure and low manufacturing cost. By adopting common mechanical components and connection methods, the entire device is easy to manufacture and maintain.
