[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] The utility model discloses a stirring arm which is easy to disassemble and replace parts. When in use, each part is first fixed. After assembly, the mixer is started. The stirring arm and the blades will inevitably suffer from wear during operation. The wear of each part only needs to replace the part with problems, which greatly reduces the cost. The stirring arm is an assembled type as a whole, and each important part can be replaced and assembled. It is convenient and quick to assemble. At the same time, the parts are small in size and weight, which is convenient to store and transport. The connection method between the connecting rod and the stirring arm body is flexible, and the connecting rod can adjust the length of the entire stirring arm by reducing the insertion degree.
