[0048] Furthermore, the tool holder connector 200 may be fixedly mounted on the top of the power tool holder 100, or may be detachably mounted on the top of the power tool holder 100;

[0049] If a fixed installation method is adopted, the whirlwind milling cutter seat is equipped with a cutter seat connector 200 of different specifications for different machine tool models; different specifications here refer to different sizes, such as some cutter seat connectors 200 have a large diameter, and some cutter seat connectors 200 have a smaller diameter, but the principle remains the same.

[0050] If a detachable installation method is adopted, the tool holder connector 200 can be installed on the power tool holder 100 by screw fixing. In order to adapt to different types of machine tools, tool holder connectors 200 of different specifications are assembled on the power tool holder 100 before use;

[0051] Furthermore, a sleeve hole is provided at the lower part of the power tool holder 100, and the rotating sleeve 300 is assembled in the sleeve hole, and the rotating sleeve 300 can rotate in the sleeve hole.
