[0033] Working principle and effect:

[0034] When the staff uses the stirring tank to perform the chemical synthesis stirring operation of the drug, the chemical stirring tank is small, and when the stirring structure needs to be fixed on the side ear of the stirring tank, the positioning frame 2 at the bottom end of the fixed main shaft 1 is pressed against the bottom of the side ear, the balance frame 3 is lowered, and the pressing screw sleeve 4 is rotated, so that the clamping plate 24 below the balance frame 3 can be pressed against the top of the side ear, and the positioning frame 2 is cooperated to complete the rapid positioning.

[0035] Turn on the control switch of the motor 6, the motor 6 starts to work, driving the stirring rod 10 at the end of the main shaft to rotate, and the block 12 installed on the outside of the screw of the circular plate 11 at the bottom end of the stirring rod 10 starts to rotate synchronously. The block 12 drives the outer connecting plate 15 and the triangular scraper 16 to start rotating. The triangular scraper 16 attached to the inner wall of the stirring tank scrapes off the adhered powdered drug lumps, and cooperates with the round rod 18 inside the fixed ring 17 to rotate. The crushing wheel 19 can perform secondary crushing on the scraped powdered drug structure, making it easier to stir and mix it into the drug solution, so as to improve the efficiency of drug chemical synthesis stirring and mixing, and maintain the quality of the produced drugs. Before stirring, the staff can rotate the first threaded shaft 9 according to the size of the stirring tank, and control the moving block 5 to move open or retract inside the balance frame 3 to change the stirring position of the stirring rod 10, so as to stir and mix the drugs more accurately.
