The upper end of the driving element 10 is drivingly connected with a driving shaft 40, and the upper end outer wall of the driving shaft 40 is provided with a first groove 41, and the first groove 41 extends along the length direction of the driving shaft 40; the transmission member 20 is cylindrical, and the transmission member 20 is vertically penetrated with a through hole 21, and the inner wall of the through hole 21 is provided with a convex strip 22; the lower end outer wall of the knife shaft 30 is provided with a second groove 31, and the second groove 31 extends along the length direction of the knife shaft 30.

[0033] The upper end of the driving shaft 40 is inserted into the inner side of the transmission member 20, and the convex strip 22 is engaged with the first groove 41 to realize the transmission between the driving shaft 40 and the transmission member 20; the lower end of the knife shaft 30 is inserted into the inner side of the transmission member 20, and the boss is engaged with the second groove 31 to realize the transmission between the transmission member 20 and the knife shaft 30; through the above transmission mechanism, the driving element 10 drives the knife shaft 30 to rotate to achieve stirring and cutting. When in use, the driving element 10 and the transmission member 20 are fixedly connected and both installed in the mixer base, while the knife shaft 30 and the transmission member 20 are detachably connected, and the knife shaft 30 is installed in the mixing container; since the knife shaft 30 and the transmission member 20 are detachably connected, the two can be separated for cleaning. At the same time, the first groove 41 is distributed in a circumferential array on the outer wall of the driving shaft 40, the convex strip 22 is distributed in a circumferential array on the inner wall of the perforation 21, and the second groove 31 is distributed in a circumferential array on the outer wall of the knife shaft 30; further improve the transmission efficiency.
