[0032] As Figure 2 , Figure 3 and Figure 5 shown, each of the stirring components 20 includes a stirring blade 21 and a balancing member 22 that are detachably stacked and combined with the shaft body 11 along the axial direction. The stirring blade 21 includes an assembling portion 211, a blade body 212, a clamping hole 213, and a cutting edge portion 214. The assembling portion 211 is plate-shaped. The blade body 212 extends from the assembling portion 211 along a radial direction, and the thickness of the blade body 212 is greater than the thickness of the assembling portion 211. The clamping hole 213 is provided through the assembling portion 211 and is configured as a hexagon corresponding to the circumferential surface of the shaft body 11. The cutting edge portion 214 is provided on one side of the blade body 212. The stirring blade 21 of each of the stirring components 20 is sleeved and clamped on the shaft body 11 with its clamping hole 213. In other embodiments, the stirring component 20 and the shaft body 11 can also be clamped and connected by means of key grooves or pins, etc.

[0033] As Figure 2 , Figure 3 and Figure 6As shown, the balance member 22 of each stirring assembly 20 includes an assembling portion 221, a counterweight portion 222, and a engaging hole 223; the assembling portion 221 is plate-shaped, the counterweight portion 222 is disposed on one side of the assembling portion 221, and the thickness of the counterweight portion 222 is greater than that of the assembling portion 221. The engaging hole 223 is disposed through the assembling portion 221 and is configured as a hexagon corresponding to the circumferential surface of the shaft body 11. The engaging hole 223 of the balance member 22 of each stirring assembly 20 is sleeved and engaged with the shaft body 11. The balance member 22 of each stirring assembly 20 can further be inclinedly provided with a guiding surface 224, so that the balance member 22 of each stirring assembly 20 has less resistance during rotation and can reduce noise; wherein, the guiding surface 224 of the balance member 22 of each stirring assembly 20 faces the opposite direction to the cutting edge portion 214 of its stirring blade 21.

[0034] As Figure 2 and Figure 7 shown, the blade body 212 of the stirring blade 21 of each stirring assembly 20 corresponds to the position of the counterweight portion 222 of the balance member 22 of the stirring assembly 20 and forms a moment balance; the two blade bodies 212 of the two stirring blades 21 of the two stirring assemblies 20 extend radially in opposite directions, and the two cutting edge portions 214 of the two stirring blades 21 of the two stirring assemblies 20 face opposite sides respectively.

[0035] As Figure 2 , Figure 3 and Figure 8 shown, the spacer 30 is disposed between two adjacent stirring assemblies 20. The spacer 30 is tubular and includes two opposite ends. The spacer 30 is sleeved on the shaft body 11, and the two ends of the spacer 30 respectively abut against two adjacent stirring assemblies 20; specifically, one end of the spacer 30 abuts against the assembling portion 221 of the balance member 22 of one stirring assembly 20, and the other end of the spacer 30 abuts against the assembling portion 211 of the stirring blade 21 of the other stirring assembly 20.

[0036] As Figure 2 , Figure 3 and Figure 8 shown, the locking member 40 is screwed and coupled to the screwing portion 13; the clamping member 50 is tubular, sleeved on the shaft body 11 and abuts against the assembling portion 221 of the balance member 22 of one stirring assembly 20 at one end. In a preferred embodiment of the present invention, the length of the clamping member 50 is greater than the length of the spacer 30; the gasket 60 is annular, sleeved on the shaft body 11 and disposed between the locking member 40 and the other end of the clamping member 50.

[0037] As Figure 1 and Figure 10As shown, the mounting shaft 10 can be sleeved on the drive shaft 81 of a drive device 80 through a provided sleeving hole 15 and is located within a stirring barrel 70. When the drive device 80 operates, it can drive the mounting shaft 10 to rotate. Since each stirring blade 21 is engaged with the shaft body 11 of the mounting shaft 10 through its engaging hole 213, the mounting shaft 10 can drive the stirring blades 21 of the two stirring assemblies 20 to rotate and stir food ingredients within the stirring barrel 70.

[0038] Furthermore, each balancing member 22 is engaged with the shaft body 11 of the mounting shaft 10 through its engaging hole 223. Therefore, the mounting shaft 10 can drive the balancing members 22 of the two stirring assemblies 20 to rotate and maintain balance with the stirring blades 21 of the two stirring assemblies 20 in the radial direction.

[0039] Each stirring assembly 20 of the present utility model includes a separately provided stirring blade 21 and a balancing member 22. The blade body 212 of the stirring blade 21 and the weight portion 222 of the balancing member 22 correspond to each other in position in the radial direction and form a moment balance, enabling the present utility model to stir efficiently, avoiding poor stirring efficiency caused by moment imbalance, reducing the energy consumption during the operation of the present utility model, and providing an energy-saving effect.

[0040] Furthermore, the separately provided stirring blade 21 and the balancing member 22 of each stirring assembly 20 can be replaced separately when the stirring blade 21 wears. Compared with the existing stirring blades with an integrally provided blade body and weight portion, the present utility model can replace the stirring blade 21 of each stirring assembly 20 separately, reducing the waste of manufacturing materials and costs brought about by discarding the integrally provided weight portion and also reducing the usage cost of the present utility model.
