[0046] The stirring drive device drives the stirring shaft 5 to rotate, thereby driving the first stirring blade 9 to rotate and stirring the raw materials in the stirring chamber 3. Since the telescopic shaft 8 can move up and down in the telescopic groove 6, it drives the first stirring blade 9 to move up and down, making the stirring range of the first stirring blade 9 larger and increasing the stirring effect.

[0047] like Figure 3 As shown, the telescopic drive device includes:

[0048] The telescopic spring 13 is installed in the telescopic groove 6 and is located between the bottom surface of the telescopic groove 6 and the lower end of the telescopic shaft 8.
