[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the device is composed of a syringe consisting of a barrel 1, a connector 2 with a tapered thread passing through the left side of the barrel 1, a needle 3 fixedly arranged on the left side of the connector 2, and a handle 4 fixedly arranged on the right side of the bottom of the barrel 1. A volume control component 5 is arranged at the middle end of the bottom of the barrel 1, and a drive component 6 is arranged inside the barrel 1; the volume control component 5 includes a rectangular frame 501 fixedly arranged at the middle end of the bottom of the barrel 1, a rotating rod 502 is rotatably passed through the bottom of the rectangular frame 501, an indicator plate 503 slidingly connected at the lower end of the rectangular frame 501 is threadedly sleeved on the outside of the rotating rod 502, a scale 504 is fixedly arranged on the left side of the rectangular frame 501, and the drive component 6 includes a partition plate 601 fixedly arranged at the middle end of the inside of the barrel 1, a first rotating pin 602 is transferred to the right side of the inside of the barrel 1, a second rotating pin 603 is transferred to the right side of the inside of the barrel 1, and the front and rear ends of the first rotating pin 602 and the second rotating pin 603 are A first pulley 604 is fixed at both ends, and the two first pulleys 604 are connected by a first toothed belt 605 that is tightly matched. A third rotating pin 606 is connected to the middle end of the handle 4. The third rotating pin 606 and the second rotating pin 603 are fixedly sleeved at the middle end outside with a second pulley 607. The outsides of the two second pulleys 607 are connected by a second toothed belt 608 that is tightly matched. The second toothed belt 608 runs through the cylinder 1, and a pull plate 609 fixed on the right side of the outside of the second toothed belt 608 is slidably connected to the handle 4. A limiting rod 610 fixed on the front left side of the pull plate 609 runs through the rectangular frame 501. A connecting rod 611 fixed at the bottom of the first toothed belt 605 slides through the partition 601, and a rubber plate 612 fixed on the left side of the connecting rod 611 is slidably connected to the cylinder 1.

[0023] The user first rotates the rotating rod 502, and through the screw transmission of the rotating rod 502 and the indicating plate 503, the indicating plate 503 moves along the direction of the rectangular frame 501 until the value on the scale 504 pointed to by the indicating plate 503 reaches the range required by the user. The user then holds the handle 4 with the right hand, punctures the needle 3 into the body of the animal, and then presses the pull plate 609 downward with the thumb of the right hand, so that the pull plate 609 drives the second toothed belt 608 to link the second pulley 607 together with the third rotating pin 606 and the second rotating pin 603 to rotate clockwise. Rotate, at this time, the second rotating pin 603 drives the first pulley 604 to rotate clockwise in conjunction with the first toothed belt 605, and the first toothed belt 605 drives the connecting rod 611 and the rubber plate 612 to move leftward along the direction of the cylinder 1, so that the medicine liquid on the left side of the cylinder 1 is injected into the animal body through the connecting head 2 through the needle 3. When the pull plate 609 and the limit rod 610 contact the indicator plate 503, at this time, the pull plate 609 can no longer continue to move downward along the direction of the handle 4. At this time, the amount of medicine injected into the animal body reaches the user's required range. Example 2

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, a spring 7 is fixedly provided at the bottom of the pull plate 609, and one end of the spring 7 away from the pull plate 609 is fixedly connected to the handle 4, a one-way valve 8 is fixedly provided inside the connector 2, a mounting tube 9 is fixedly penetrated through the left side of the bottom of the cylinder 1, a stop valve 10 is fixedly provided inside the mounting tube 9, the interior of the mounting tube 9 is connected with the interior of the cylinder 1, a box body 11 is provided on the left side of the bottom of the cylinder 1, the box body 11 is fixedly sleeved on the outside of the mounting tube 9, and the top surface of the box body 11 and the bottom surface of the cylinder 1 fit each other, a drain pipe 12 is fixedly penetrated through the upper side of the front end of the outside of the box body 11, a valve 13 is rotatably penetrated on the outer wall of the drain pipe 12, the interior of the drain pipe 12 is connected with the interior of the box body 11, a guide hole 14 is integrally provided on the right side of the inside of the rectangular frame 501, the guide hole 14 is a through hole design, and the size of the external cross-section of the rubber plate 612 is consistent with the size of the cross-section inside the cylinder 1.

[0025] According to the operation method in Example 1, when the user presses the pull plate 609, the spring 7 is deformed. After the liquid medicine is injected into the animal, the user takes the needle 3 out of the animal and then releases the pull plate 609. The pull plate 609, the rubber plate 612 and the limit rod 610 are reset by the rebound force of the spring 7. The suction force generated when the rubber plate 612 is reset discharges the liquid medicine inside the box body 11 from the installation tube 9 to the left side of the cylinder body 1. The one-way valve 8 can prevent the suction force of the rubber plate 612 from discharging the outside air into the cylinder body 1. The stop valve 10 can prevent the liquid medicine inside the cylinder body 1 from flowing back into the box body 11 from the installation tube 9. The user then separates the connector 2 together with the needle from the cylinder body 1, and replaces the new connector 2 and needle 3 to inject the liquid medicine into other animals. When the liquid medicine inside the box body 11 is used up, the staff can inject the new liquid medicine into the box body 11 from the discharge tube 12, and then close the valve 13.
