The gear mechanism has simple structure and stable operation. In a specific implementation process, the driving gear 6 and/or the driven gear 7 can be set to be a bevel gear, so that the angle of the rotation center line between the main shaft 2 and the cutter shaft 4 can be adjusted while the transmission is carried out through a gear mechanism.

In some embodiments, the machine body 1 may be provided with a knife rest 8, and the knife shaft 4 penetrates through the knife rest 8 and is rotatably connected to the knife rest 8, so as to support the stirring knife 3 through the knife rest 8, so that the stirring knife 3 is firmly connected and operates stably. In practical application, the knife rest 8 can be fixed in the protective cover 14 through a bolt or a clamping structure, so that the bottom side of the knife rest 8 extends outwards to form a bearing groove 9, a bearing 10 is arranged in the bearing groove 9, a sealing ring 11 is arranged on the outer side of the bearing 10 to seal the bearing 10, and the knife shaft 4 penetrates through the sealing ring 11, the bearing 10 and the knife rest 8. Thus, the top end of the cutter shaft 4 is positioned at the top of the tool rest 8 and connected with the main shaft 2, and the bottom end of the cutter shaft 4 is positioned at the bottom of the tool rest 8 and connected with the cutter body 5. As a preferable scheme, the tool holder 8 can be a closed structure, and the tool holder 8 and the protective cover 14 can be hermetically connected, so that the tool holder 8 can support the stirring tool 3, can block the food 15, so as to prevent the food 15 from entering the stirring rod 13, prevent the main shaft 2 and the gear mechanism from directly contacting with the food 15, can prevent the stirring rod 13 from containing dirt, make the stirring device easy to clean, and can also prolong the service life of the stirring device.

In some embodiments, a plurality of stirring blades 3 are uniformly distributed around the circumference of the main shaft 2. For example, when the number of the agitating blades 3 is two, two agitating blades 3 may be symmetrically disposed on both sides of the main shaft 2, when the number of the agitating blades 3 is three, three agitating blades 3 may be disposed at intervals of 120 ° from each other around the circumferential direction of the main shaft 2, and when the number of the agitating blades 3 is four, four agitating blades 3 may be disposed at intervals of 90 ° from each other around the circumferential direction of the main shaft 2. Thus, the stirring device can uniformly stir in multiple directions, and the operation is stable. It should be noted that the number of the stirring blades 3 is not limited to two, three, or four.

In some embodiments, the minimum included angle between the rotation center line of the stirring blade 3 and the rotation center line of the spindle 2 may be 10 ° to 60 °. Within such angle range, this agitating unit's stirring efficiency is higher, and agitating unit cuts into speed very fast to the depth direction of food 15, and stirring effect is better, and user experience is better. As a preferred embodiment, the minimum included angle between the rotation center line of the stirring blade 3 and the rotation center line of the main shaft 2 may be 35 °. Of course, the minimum included angle between the two is not limited to 35 °, but may be, for example, 20 °, 25 °, 30 °, 40 °, 45 °, or 50 °.

The utility model discloses agitating unit, stirring sword 3 cut into food 15 along the incline direction, can comparatively laborsaving and quick cut into to the degree of depth direction of food 15 when rotatory in order to stir food 15, need not to widely mention or down press, and operation laborsaving, stirring efficiency is higher. Moreover, since the vortexes formed by the plurality of stirring blades 3 interfere with each other, the phenomenon that the stirring blades 3 are sucked by the food 15 when extending into the bottom of the food 15, which causes difficulty in operation, can be avoided.
