For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0019] Example: A milling cutter with a vibration stabilization structure, such as Figures 1-5 As shown, the assembly includes a fixed base 1, a connecting component, a first screw 3, an elastic sleeve 5, an extension connecting rod 6, a plug 61, an extension component, a blade 13, a second screw 14, and a blade 15. The fixed base 1 has a through hole in the middle. The connecting component is connected to the bottom of the fixed base 1. The extension connecting rod 6 is connected to the connecting component by the first screw 3. The plug 61 is fixedly connected to the top of the extension connecting rod 6. The plug 61 is inserted into the through hole of the fixed base 1. The elastic sleeve 5 is fixedly connected between the plug 61 and the inner wall of the through hole. The elastic sleeve 5 can make the plug 61 fit tightly with the through hole, avoiding vibration during use due to gaps between the plug 61 and the through hole. The extension component is connected to the bottom of the extension connecting rod 6. The blade 13 is connected to the bottom of the extension component. The blade 15 is connected to the outer wall of the blade 13 by the second screw 14.
