For example, a conveniently replaceable milling cutter with Chinese patent application number CN202021320024.2 includes a milling cutter, and a limiting mechanism matching the milling cutter is provided on the outer side of the milling cutter. The milling cutter includes a fixed column, and four triangular connecting blocks arranged in a square are fixedly installed on the top peripheral side of the fixed column. A cutter head is fixedly installed at the bottom end of the fixed column. The limiting mechanism includes a limiting assembly, and four elastic assemblies arranged in a square are slidably connected inside the limiting assembly. A moving assembly is slidably connected to the outer side of the limiting assembly.
