[0012] Preferably, the splicing screw is a headless screw, and the splicing screw can be fully inserted into the splicing thread groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model discloses a stirring blade with an adjustment function. By rotating the angle of the mounting plate on the frame and then locking the positioning screw in the docking thread groove, the angle of the blade body can be changed. The change of the angle of the blade body can adjust the force of the blade body on the stirred object during stirring. The movable blade is flipped on the blade body through the docking shaft, and then the splicing screw penetrates the movable blade and is installed in the blade body. The blade body and the movable blade form a new shape, which is larger and thinner as a whole than the previous shape, and the edges and corners become sharper and more cutting. The change of the angle of the blade body and the switching between the new and old shapes can be suitable for different stirring needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 A stirring blade with an adjustment function comprises a mounting frame 1 and an external blade 2. The external blade 2 is arranged on the outside of the mounting frame 1. The mounting frame 1 comprises a frame body 11, a docking thread groove 12 and a docking cavity 13. The docking cavity 13 is opened on all four sides of the frame body 11. A circle of docking thread grooves 12 are arranged on the outside of the docking cavity 13, and the docking thread grooves 12 are arranged in an array around the docking cavity 13. The positioning screw 23 is threadedly connected to the docking thread groove 12. The external blade 2 comprises a blade body 21, a mounting plate 22, a positioning screw 23, a movable blade 25, a docking shaft 26 and a splicing screw Groove 27, one end of the blade body 21 is fixedly connected to the mounting plate 22, and a positioning screw 23 is provided on the mounting plate 22. A movable blade 25 is provided on one side of the blade body 21, and a docking shaft 26 is provided between the movable blade 25 and the blade body 21. The movable blade 25 can be flipped and extended on the blade body 21 through the docking shaft 26 to change the overall shape of the external blade 2. A splicing thread groove 27 is provided on the docking shaft 26 and the blade body 21, and a splicing screw is provided inside the splicing thread groove 27, and the splicing thread groove 27 is threadedly connected to the splicing screw.
