This is convenient for adapting to the installation of stirring barrels of different lengths, and the stirring blades 112 on the multiple short shafts 102 of the stirring shaft 1 can stir the materials at different heights in the stirring barrel, thereby improving the stirring effect of the stirring shaft 1.

[0028] Please refer to Figure 2 It is shown that in the embodiment, the upper end of the short shaft 102 is provided with a first polygonal groove 104, and the bottom end of the short shaft 102 is in a polygonal column structure. The bottom end of a short shaft 102 is slidably connected in the first polygonal groove 104 of another short shaft 102. This is convenient for guiding the sliding of another short shaft 102 through the first polygonal groove 104 on the short shaft 102, thereby improving the stability of the sliding connection between the adjacent two short shafts 102.
