When installing the cutting mechanism 4, a fastener such as a bolt is used to make one side of the clamping ring 32 approach and lock the clamping portion 31. In a traditional fixing structure, the force applied to one side of the clamping ring 32 will generate a force on one side of the slide 3 through the other side of the clamping ring 32, which will The slide seat 3 has a tendency to flip, so that the slide rail 52 and the slider 51 of the slide seat 3 are continuously subjected to force, resulting in deformation, which affects the sliding accuracy of the slide seat 3. In the embodiment of the utility model, a vertically penetrating notch 34 is provided on the inner wall of the clamping ring 32.
