[0039] The blade shaft 3 passes through the stirring rod 5 and the stirring cover 6. The stirring blade 4 is provided at the bottom of the blade shaft 3. The stirring blade 4 is located in the stirring cover 6.

[0040] A sliding bearing assembly 7 is sleeved on the cutter shaft 3 and allows the cutter shaft 3 to move relative to the sliding bearing assembly 7;

[0041] Among them, the rotating part 1 can rotate relative to the movable part 2 to drive the movable part 2 to move axially along the blade shaft 3, and the movable part 2 is connected to the stirring rod 5 to drive the stirring rod 5 to move axially, or the movable part 2 is connected to the blade shaft 3 to drive the blade shaft 3 to move axially to adjust the relative position of the stirring blade 4 and the stirring cover 6.

[0042] Based on the adjustable stirring mechanism of this embodiment, the user can drive the stirring rod 5 or the blade shaft 3 to move axially by adjusting the component to adjust the position of the stirring blade 4 relative to the stirring cover 6, so that the stirring blade 4 can have multiple cutting positions, thereby improving the cutting effect of food and meeting the user's different needs for food cutting.

[0043] In this embodiment, the movable part 2 and the rotating part 1 are both hollow structures, and the knife shaft 3 passes through the movable part 2 and the rotating part 1 to be detachably connected to the driving mechanism of the mixer, thereby realizing the driving of the knife shaft 3 based on the driving mechanism.

[0044] Furthermore, if Figure 2 、 Figure 3 、 Figure 4 As shown, the rotating member 1 and the moving member 2 in this embodiment are threadedly connected. When the rotating member 1 rotates, it can drive the moving member 2 to move axially.

[0045] Continue to combine Figure 2 and Figure 3 As shown, the adjustable stirring mechanism in this embodiment further includes a connector 8, which is disposed in the stirring rod 5 and has one end extending out of the stirring rod 5. As shown in the figure, the connector 8 in this embodiment is approximately torch-shaped, with the lower end located in the stirring rod 5 and the upper end located outside the stirring rod 5. The rotating member 1 is sleeved on the end of the connector 8 located outside the stirring rod 5 and can rotate relative to the connector 1. The moving member 2 is in the shape of a hollow cylinder, which is sleeved on the portion of the connector 8 located in the stirring rod 5 and is threadedly connected to the rotating member 1. The blade shaft 3 is inserted into the connector 8 along the axis of the connector 8 and passes through the connector 8.

[0046] Continue to combine Figure 4 and Figure 5 As shown, in order to limit the position between the connector 8 and the blade shaft 3 while allowing the blade shaft 3 to move within the stirring rod 5, the blade shaft 3 is provided with a limit bearing 12. The bearing has a circle of ridges for abutting against the connector 8 to support the limit connector 8. The limit bearing 12 is fixed to the blade shaft 3 by an upper retaining spring and a lower retaining spring respectively.

[0047] In one embodiment, the movable member 2 is located within the stirring rod 5 and is detachably connected to the stirring rod 5. When the movable member 2 moves axially, it drives the stirring rod 5 to move axially along with it. Specifically, a snap 9 is provided between the movable member 2 and the stirring rod 5. The specific structure of the snap 9 is not specified, as long as the movable member 2 and the stirring rod 5 are detachably connected via their respective snaps 9. By connecting the movable member 2 to the stirring rod 5, the movement of the movable member 2 can drive the stirring rod 5 up and down, thereby adjusting the position of the stirring blade 4 relative to the stirring cover 6.

[0048] In order for the stirring rod 5 to move successfully and smoothly, there must be space within the stirring rod 5 for the moving member 2 to move, and the stirring rod 5 must also have sufficient space to move. To achieve this, in this embodiment, an annular groove 10 is formed axially inwardly in the middle portion of the rotating member 1. For example, as shown in the figure, the annular groove 10 corresponds to the top end of the stirring rod 5. When the moving member 2 drives the stirring rod 5 to move, the stirring rod 5 enters and exits the annular groove 10.
