The threaded block 10 is fixedly installed on the outer wall of the insertion rod 9, and the mounting rod 801 is movably installed on the bottom of the driving motor 8. A limiting rod 802 is fixedly installed on one side of the mounting rod 801. A stirring chamber 11 is provided inside the stirring tank 1. The rotating rod 12 is movably sleeved inside the stirring chamber 11. A stirring blade 13 is fixedly installed on the bottom circumference of the rotating rod 12. A movable rod 103 is fixedly installed on the top of the rotating rod 12. A card interface 104 is provided inside the movable rod 103. The inside of the card interface 104 and the limiting rod 802 are adapted to each other. By setting a movable part, the driving motor 8 can be detached from the card connection when it stops working, so that the liquid can still drive the rotating rod 12 to rotate during the process of generating centrifugal force, avoiding deformation during the working process.

[0023] The working principle of this utility model:

[0024] In the preparation step, during the operation, the input pipe 5 and the liquid outlet pipe 4 are respectively connected to the working position. At this time, the liquid can be injected into the stirring tank 1 through the input pipe 5. At this moment, the driving motor 8 is driven. During the driving process, the stirring blade 13 fixedly connected to the bottom of the rotating rod 12 can mix the liquid inside the stirring chamber 11.

[0025] Working steps: when the work is completed, the liquid continues to rotate due to centrifugal force and the drive motor 8 stops rotating, you only need to pull the movable plate 6 to one side, and during the pulling process, the limiting rod 802 will be detached from the inside of the movable rod 103. At this time, the centrifugal force generated by the liquid will drive the movable rod 103, the rotating rod 12, and the stirring blade 13 to continue rotating, so that the rotating rod 12 will not be deformed due to the centrifugal force during the work process, thereby providing protection for it.

[0026] Ending step, when the work is completed, push the movable plate 6 to the other side, which allows the limiting rod 802 to be clamped inside the card interface 104 to form a limiting force, so that the limiting rod 802 can be limited inside the card interface 104, so that 810 can be connected to the movable rod 103, thereby facilitating the limitation and connection, and then the insertion rod 9 and the inside of the fixed port 102 are clamped with each other, and then the threaded block 10 is threadedly installed on the outer surface of the insertion rod 9, thereby forming a limiting effect.
