A buffer mechanism 3 is provided between the embedded isolation ring 22 and the threaded barrel 21 and between the protective sleeve 14 and the limiting sleeve 13.
[0026] In this embodiment, when the staff uses the boring bar device for cutting and manufacturing, they can install the boring bar on the docking device for cutting, and the vibration generated during the cutting process can be protected by respectively arranging a limiting sleeve 13 and a protective sleeve 14 at both ends of the docking rod 15 to install and use the docking rod 15. At the same time, the fixing mechanism 2 is used for docking at the installation location of the cutter head. The staff can rotate the embedded isolation ring 22 to dock the inner surface of the embedded isolation ring 22 to the end of the docking rod 15 away from the protective pad ring 12 through threaded rotation, so that it can be fixed on the cutting device for cutting. In this way, the vibration generated by the docking rod 15 during the working process can be weakened by the protective sleeve 14, and buffered and protected by the buffer mechanism 3, thereby improving its practicality in actual use.
