A plurality of stirring blades 60 are vertically provided on the side of the stirring rod 6.

[0037] In this embodiment, the diameter of the center hole of the bevel gear 2 is larger than the diameter of the shaft 11, and the shaft hole of the bevel gear 2 does not contact the outer wall of the shaft 11, so that the bevel gear 2 does not generate unnecessary vibration, thereby enabling the entire mixing device to work stably.

[0038] In this embodiment, a mounting hole having the same diameter as the rotating shaft 11 is provided on the extension rod 31, and the connecting block 54 is clamped in the connecting groove 30 and fixed by bolts, so that the mixing barrel 5 can be firmly and stably fixed when it revolves.
