The rotating rod is rotatably connected to the mixing tank 2 and a mixing plate 15 is fixedly installed on the outer wall. Multiple sets of mixing plates 15 are provided.

[0024] The slide bar 7 is polygonal and slidably connected to the support plate 9. The connecting sleeve 4 has a movable groove 16, and multiple sets of stops 10 slide within the movable groove 16. The tops of multiple sets of compression springs 11 are fixedly connected to the inner wall of the movable groove 16.

[0025] The top surface of multiple sets of stop blocks 10 is fixedly provided with guide blocks 17, and the inner wall of the movable groove 16 is provided with guide grooves 18. Multiple sets of guide grooves 18 are provided and are slidably connected to multiple sets of guide blocks 17 respectively.

[0026] The outer wall of the adjusting sleeve 5 is connected to a reset spring 19. Multiple sets of reset springs 19 are provided, and each set of the top is connected to a positioning block 20. The multiple sets of positioning blocks 20 are slidably connected to the adjusting sleeve 5. The outer wall of the connecting sleeve 4 is provided with a positioning groove 21. Multiple sets of positioning grooves 21 are provided and are respectively connected to the bottom of the multiple sets of positioning blocks 20.

[0027] The outer wall of the connecting sleeve 4 is provided with a rotating sleeve 22. The outer wall of the rotating sleeve 22 is provided with a limiting groove 23. Multiple sets of limiting grooves 23 are provided, and each one end is provided with an unlocking hole 24. The outer wall of the connecting sleeve 4 is provided with a limiting sleeve 25. The bottom surface of the limiting sleeve 25 is fixedly provided with a support rod 26. Multiple sets of support rods 26 are provided, and each one end is fixedly provided with a limiting block 27.

[0028] Multiple sets of support rods 26 are provided with push springs 28 on their outer sides. The top of each set of push springs 28 is fixedly connected to the sliding sleeve. The bottom of each set of push springs 28 is set in an arc shape. The outer wall of the connecting sleeve 4 is fixedly provided with guide blocks 29. Multiple sets of guide blocks 29 are provided and are slidably connected to the sliding sleeve.

[0029] In this embodiment, during use, multiple sets of external connecting pipes 12 are threadedly connected to external medicine delivery pipes or storage containers. The rotating adjusting sleeve 5 is threadedly engaged with the screw 6, causing the sliding rod 7 to push the push block 8 against multiple sets of stop blocks 10. This causes the multiple sets of stop blocks 10 to slide along the movable groove 16 and compress multiple sets of compression springs 11. The flow space within the movable groove 16 is adjusted by the multiple sets of stop blocks 10, and the flow rate and volume of the medicine are adjusted by adjusting the flow area of ​​the medicine. Subsequently, rotating the rotating sleeve 22 causes multiple sets of support rods 26 to slide to the unlocking hole. The inner contact of the 24 restricts the limiting sleeve 25. Multiple sets of push springs 28 push the limiting sleeve 25 to slide along multiple sets of guide blocks 29 and abut against the top of multiple sets of positioning blocks 20, so that the multiple sets of positioning blocks 20 abut against the positioning groove 21 and squeeze the reset spring 19. Then the rotating sleeve 22 is rotated again, so that multiple sets of limiting blocks 27 abut against the top surface of the rotating sleeve 22, thereby restricting the limiting sleeve 25 and completing the positioning of the adjusting sleeve 5. At the same time, the motor 13 is started to drive the rotating rod 14 to rotate, and the rotating rod 14 drives multiple sets of mixing plates 15 to stir and mix the medicine liquid.

[0030] More specifically, when the flow rate of the liquid medicine needs to be adjusted again, rotating the rotating sleeve 22 causes the multiple unlocking holes 24 to move below the limiting block 27, pushing the limiting sleeve 25 to release the contact with the multiple positioning blocks 20 and causing the support rod 26 to be inserted into the unlocking hole 24 and squeeze the multiple push springs 28. Rotating the rotating sleeve 22 again causes the multiple support rods 26 to slide into the limiting groove 23 to restrict the limiting sleeve 25. The multiple reset springs 19 pull the positioning block 20 so that its bottom end is disengaged from the positioning groove 21, releasing the positioning of the adjusting sleeve 5. Then the adjusting sleeve 5 can be rotated again to adjust the liquid medicine flow space between the multiple blocks 10.

[0031] In summary, during use or operation of the overall equipment: In use, multiple sets of external connecting pipes 12 are threadedly connected to external medicine delivery pipes or storage containers. The rotating adjusting sleeve 5 is threadedly engaged with the screw 6, causing the sliding rod 7 to push the push block 8 against multiple sets of stop blocks 10. This causes the stop blocks 10 to slide along the movable groove 16 and compress multiple sets of compression springs 11. The flow space within the movable groove 16 is adjusted by the multiple sets of stop blocks 10, thereby regulating the flow rate and volume of the medicine by adjusting the flow area. Subsequently, rotating the rotating sleeve 22 causes the multiple sets of support rods 26 to slide... The movement extends to the unlocking hole 24, contacting the limiting sleeve 25. Multiple sets of push springs 28 push the limiting sleeve 25 to slide along multiple sets of guide blocks 29 and abut against the top of multiple sets of positioning blocks 20, so that the multiple sets of positioning blocks 20 abut against the positioning groove 21 and squeeze the reset spring 19. Then, the rotating sleeve 22 is rotated again, so that the multiple sets of limiting blocks 27 abut against the top surface of the rotating sleeve 22, thereby limiting the limiting sleeve 25 and completing the positioning of the adjusting sleeve 5. At the same time, the motor 13 is started to drive the rotating rod 14 to rotate, and the rotating rod 14 drives multiple sets of mixing plates 15 to stir and mix the medicine.

[0032] When the flow rate of the liquid medicine needs to be adjusted again, rotating the rotating sleeve 22 causes the multiple unlocking holes 24 to move below the limiting block 27, pushing the limiting sleeve 25 to release the contact with the multiple positioning blocks 20 and causing the support rod 26 to be inserted into the unlocking hole 24 and squeeze the multiple push springs 28. Rotating the rotating sleeve 22 again causes the multiple support rods 26 to slide into the limiting groove 23 to restrict the limiting sleeve 25. The multiple reset springs 19 pull the positioning block 20 so that its bottom end is disengaged from the positioning groove 21, releasing the positioning of the adjusting sleeve 5. Then the adjusting sleeve 5 can be rotated again to adjust the liquid medicine flow space between the multiple blocks 10.
