For example, the stirring teeth 50 are welded on the stirring shaft 40.
[0038] It can be understood that since the first driving element is connected with the spiral rod 20, the spiral rod 20 can be driven to rotate through the first driving element, and the spiral blades 30 can be driven to move through the spiral rod 20, so as to realize the stirring of the material.
