[0002] During the material cutting process, a tool holder with a cutter wheel and a tool holder are required to be assembled. The cutter wheel, tool holder and tool holder are all in a direction perpendicular to the material being processed. The tool holder is fixed on the tool holder, and the tool holder drives the cutter wheel to perform cutting work. During the cutting process, the material being processed should always be perpendicular to the tool holder. However, the technology for keeping curved and special-shaped materials perpendicular to the tool holder during the cutting process is not mature enough.
[0003] In the prior art, in order to ensure that the arc-shaped or special-shaped processed material is always perpendicular to the knife seat, a spring is installed at the bottom of the knife seat so that the arc-shaped or special-shaped processed material contacts the cutter wheel, squeezes the knife seat, and converts the elastic deformation generated by the spring into cutting pressure, thereby cutting the arc-shaped or special-shaped processed material. However, the method of installing a spring will reduce the sensitivity of the knife seat and the cutting accuracy. At the same time, since the elastic deformation generated by the spring is a variable, the elasticity of the spring decreases with the increase of the assembly process. Therefore, it will also cause unstable cutting pressure and low cutting quality, so that the knife seat needs to be replaced frequently, which is costly. Summary of the invention
