Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0027] Specifically, the bottom end of the stirring shaft 4 is close to the inner walls of the front and rear sides of the through hole 7, and the inner wall of the upper side of the opposite end of the plug block 8 is slidably connected with a card block 9, and the opposite end of the card block 9 is fixedly connected with a spring 17, and the opposite end of the spring 17 is fixedly connected to the inner wall of the plug block 8. The shape of the top of the plug block 8 is consistent with the shape of the inner wall of the slot 12, and the distance between the bottom end of the card block 9 and the top end of the stirring shaft 4 is the same as the thickness of the upper stirring blade 1, and the shape of the bottom end of the positioning rod 11 is consistent with the shape of the inner wall of the hole at the top of the embedded block 16. The inner diameter of the through hole 7 is larger than the outer diameter of the top of the bolt 10. The embedded block 16 is inserted into the inner wall of the slide 15 from top to bottom, and then the positioning rod 11 is respectively aligned with the top hole of the embedded block 16 and inserted, and the slot 12 is aligned with the plug block 8 and inserted. At the same time, the through hole 7 passes through the top of the bolt 10. When the bottom of the upper stirring blade 1 contacts the arc surface of the block 9, the block 9 will be forced to retract into the plug block 8, and the spring 17 will be squeezed at the same time. When the bottom of the upper stirring blade 1 is completely in contact with the top of the stirring shaft 4, the block 9 is no longer subject to force, and the block 9 is driven to reset under the elastic force of the spring 17, so that the upper stirring blade 1 is clamped and limited between the bottom of the block 9 and the top of the stirring shaft 4 to prevent it from shifting. After that, the block 9 can be pressed to retract into the plug block 8, and then the upper stirring blade 1 is taken out from the top of the stirring shaft 4. At the same time, the positioning rods 11 on both sides are pulled out from the top holes of the embedded block 16, and then the embedded block 16 and the lower stirring blade 2 are pulled out from the slide 15, so that each stirring blade can be easily cleaned.

[0028] Specifically, a threaded barrel 13 is slidably connected to the middle part of the inner wall of the stirring shaft 4, and the inner wall of the threaded barrel 13 is threadedly connected to the outer wall of the bolt 10. The left and right ends of the threaded barrel 13 are fixedly connected with connecting rods 14. The outer walls of the connecting rods 14 are respectively slidably connected to the inner walls of the two sides of the stirring shaft 4. The opposite ends of the connecting rods 14 are fixedly connected with sliding barrels 15. The outer walls of the sliding barrel 15 are respectively slidably connected to the inner walls of the grooves at the left and right ends of the stirring shaft 4. The outer walls of the engaging blocks 16 are embedded in the inner walls of the opposite ends of the sliding barrel 15. The bolt 10 is rotated to make the threaded barrel 13 slide upward on the outer wall of the bolt 10, and the sliding barrel 15 is moved up by the connecting rod 14, so that the top hole of the engaging block 16 slides on the outer wall of the positioning rod 11, and the lower stirring blade 2 is moved together, so as to adjust the gap between the bottom of the lower stirring blade 2 and the inner wall of the mixing barrel 5, and prevent the bottom of the lower stirring blade 2 from scraping the inner wall of the mixing barrel 5.

[0029] Working principle: First, align the bottom of the stirring shaft 4 with the driving shaft of the motor 6 and fix it on the inner wall of the mixing barrel 5, then place the lower stirring blades 2 on both sides of the stirring shaft 4, insert the fitting block 16 from top to bottom into the inner wall of the slide tube 15, and then align the positioning rods 11 with the top holes of the fitting blocks 16 and insert them, align the slots 12 with the plug blocks 8 and insert them, and at the same time, the through holes 7 pass through the top of the bolts 10. When the bottom of the upper stirring blade 1 contacts the arc surface of the block 9, the block 9 will be forced to retract into the plug block 8 and squeeze the spring 17. When the bottom of the upper stirring blade 1 is completely in contact with the top of the stirring shaft 4, the block 9 will not be forced and will be pressed against the spring 17. The elastic force of the block 9 drives the card block 9 to reset, so that the upper stirring blade 1 is clamped and limited between the bottom of the card block 9 and the top of the stirring shaft 4 to prevent it from shifting. Thereafter, the card block 9 can be pressed and retracted into the insertion block 8, and then the upper stirring blade 1 is taken out from the top of the stirring shaft 4. At the same time, the positioning rods 11 on both sides are pulled out from the holes on the top of the embedded block 16, and then the embedded block 16 is pulled out from the slide cylinder 15 together with the lower stirring blade 2, so that each stirring blade can be easily cleaned. The central stirring blade 3 extending from one side of the outer wall of the lower stirring blade 2 makes the center of gravity of the stirring blade balanced, and the problem of large swing of the stirring blade is not easy to occur during the rotation.
