[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4, a rounded and beveled integrated milling cutter, comprising: a tool rod 1, a tool head 2, a blade 3, a beveled end 4, a rounded end 5, a mounting screw hole 6 and an insertion rod 7, and also comprising: a groove for plug-in installation is opened above the tool rod 1, so as to facilitate the connection and installation of the milling cutter and the milling machine. This is the prior art and will not be described in detail. At the same time, considering the connection flexibility of the tool head 2 below the tool rod 1, the tool head 2 is plugged into the tool rod 1 below the tool rod 1 through the insertion rod 7. Specifically, the insertion rod 7 is coaxially fixed at the bottom end of the tool rod 1 to ensure the flexibility of the tool rod 1 plugged into the insertion rod 7. The tool head 2 is set in a cylindrical shape, and a groove for accommodating the insertion rod 7 is opened in the middle of the tool head 2.
