The wire holder 310 is fixedly installed on the inner wall of the shell 1, and the injection needle 311 is fixedly installed at the end of the water outlet pipe 39 away from the water inlet hose 38. The injection needle 311 is connected to the water inlet hose 38 through the water outlet pipe 39.

[0029] The water inlet hose 38 contacts the line inlet 34 , and the water inlet hose 38 contacts the line outlet 35 .

[0030] The wire fixer 310 contacts the water outlet pipe 39 , and a torsion spring is provided between the cover plate 33 and the receiving disc 31 , so that the cover plate 33 is driven to reset by the torsion spring.

[0031] The cover plate 33 is manually rotated. After the cover plate 33 is rotated, the water inlet hose 38 is inserted into the inlet port 34. As the water inlet hose 38 is continuously pushed, the water inlet hose 38 moves and contacts the receiving disc 31. After the water inlet hose 38 contacts the receiving disc 31, it is blocked by the receiving disc 31, causing the water inlet hose 38 to bend toward the bottom.

[0035] The bottle is placed on the top of the conveying device 41. The rotation of the shaft will drive the belt to rotate. The rotation of the belt will drive the bottle on the top to move toward the injection needle 311. When the bottle moves, it will contact and be enlarged by the guide plate 42, so that the bottle moves toward the center of the belt. When the bottle moves to the bottom of the injection needle 311, the sensing module detects the bottle, and the control module starts the servo motor 32. The rotation of the output end of the servo motor 32 will drive the rotating plate 36 to rotate. The rotation of the rotating plate 36 will drive the roller 37 to rotate. The rotation of the roller 37 will squeeze the water inlet hose 38. After being squeezed, the water inlet hose 38 will push the liquid inside to flow to the water outlet pipe 39, and then pass through the injection needle 31. 1. The medicine is discharged and unmanned processing is completed through the set program, which improves the stability of continuous operation of the device and the work efficiency. The output end of the electric push rod 43 moves toward the bottle body. The movement of the output end of the electric push rod 43 will drive the movement of the splint 1 44. The movement of the splint 1 44 will drive the movement of the reset spring 45. The movement of the reset spring 45 will drive the movement of the splint 2 46. The movement of the splint 2 46 will push the bottle body to move in the direction of the sponge plate 49, pushing the splint 2 46 to move to cooperate with the sponge plate 49. While positioning the bottle body, the sponge plate 49 will also protect the bottle body to prevent excessive pushing from causing damage to the bottle body when facing bottles of different sizes, thereby improving the protection of the device.
