[0033] Working principle: When installing the delivery pipe 9 on the water inlet pipe 6 and the water outlet pipe 7 to convey the liquid medicine, one can manually hold the sliding hole rod 23 and rotate it around the round rod 22 in the inner wall of the U-shaped block 21 to a certain angle, driving one end of the limit frame 25 to rotate to one side of the interface of the delivery pipe 9. Then, rotate the threaded rod 24 to drive the limit frame 25 to slide towards one end in the inner wall of the sliding hole frame to a certain position, and the other side presses against one side of the interface of the delivery pipe 9, driving the first catch 26 on one side to snap into the corresponding card slot 27 to limit the limit frame 25, and limiting and fixing the delivery pipe 9 on the water inlet pipe 6 and the water outlet pipe 7. In this way, when accidentally pulling or tripping over the delivery pipe 9 during use, it will not cause the connection at one end with the water inlet pipe 6 or the water outlet pipe 7 to become loose and fall off, avoiding the problem of waste caused by the overflow and leakage of the internally conveyed liquid medicine. During the distribution process, kinetic energy is provided by the drive shaft 4 to drive the rotor 5 sealed in the pump housing 1 to rotate. The liquid medicine will enter the rotor 5 sealed in the housing through the delivery pipe 9 from the water inlet pipe 6. A certain number of cutting slits 8 are distributed on the rotor 5. The cutting slits 8 form openings on the rotor 5 for cutting the conveyed liquid medicine. When the opening on the rotor 5 coincides with the water outlet pipe 7 on the pump housing 1, the liquid medicine in the rotor 5 will be discharged from the water outlet pipe 7, achieving the effect of distribution and conveyance.

[0034] When the limit frame 25 is damaged and needs to be replaced or when it is not in use, one can manually press the second catch 36 to receive it into the inner wall of the chute 34, driving the spring 35 and the telescopic rod 37 to contract, pulling out one end from the card hole 32, and then pulling the convex block 33 to pull it out from the inner wall of the groove block 31, so that the U-shaped block 21 can be detached from the pump housing 1, facilitating its replacement.
