[0024] Refer to Figure 3 - Figure 4The adjusting screw block 3 is threadedly connected to one side of the inner wall of the connecting seat 2, and is used to cooperate with the push rod 10 to realize the adjustment of the injection dose. The threaded groove II 17 is threadedly connected with the threaded groove I 16, which is used to connect the needle cylinder 1 and the connecting seat 2. The threaded groove I 16 is arranged on the outer wall of the needle cylinder 1. The needle cylinder 1 is generally made of transparent or translucent plastic or glass material, and has a cylindrical shape, which is convenient for observing the liquid capacity and the injection process. The needle cylinder 1 is fixedly connected with the mounting seat 12. The mounting seat 12 is fixedly connected with the liquid outlet pipe 13 inside. The mounting seat 12 is threadedly connected with the fixed seat 14. The liquid outlet pipe 13 is slidably connected to the inner wall of the fixed seat 14.

[0025] Working principle: according to the required injection dose of the medicine, rotate the adjusting screw block 3. By rotating the adjusting screw block 3, the position of the adjusting screw block 3 on the push rod 10 can be changed. The piston 6 slides in the needle cylinder 1. Therefore, the position of the adjusting screw block 3 determines the maximum stroke of the push rod 10 and the piston 6 that can be pushed forward, thereby realizing the accurate adjustment of the injection dose. When a small dose of medicine needs to be injected, rotate the adjusting screw block 3 to the rear end of the push rod 10 to shorten the distance between the adjusting screw block 3 and the piston 6. In this way, during the pushing process, the push rod 10 and the piston 6 can only move a short distance forward, thereby accurately controlling the injection dose. When a large dose of medicine needs to be injected, rotate the adjusting screw block 3 to the front end of the push rod 10 to increase the distance between the adjusting screw block 3 and the piston 6. During injection, the needle 15 is accurately inserted into the injection site of the large animal. Then, when the connecting rod II 5 is pushed, the connecting rod II 5 rotates around the connecting point of the connecting rod I 4, and the clamping block 9 slides on the outer wall of the push rod 10. The clamping block 9 cooperates with the clamping groove 7 on the outer wall of the push rod 10, so that the push rod 10 moves forward under the pushing of the clamping block 9. The piston 6 fixedly connected to one end of the push rod 10 slides forward in the needle cylinder 1, and applies pressure to the liquid in the needle cylinder 1. With the forward movement of the piston 6, the liquid in the needle cylinder 1 is squeezed and flows to the needle 15 through the liquid outlet pipe 13 inside the mounting seat 12. During the pushing process, the spring 8 is compressed, providing certain buffer and auxiliary power for the pushing, making the pushing process more stable, and also helping the reset of the push rod 10 and the piston 6 after the injection is completed. After the injection is completed, rotate the fixed seat 14 to separate the fixed seat 14 from the mounting seat 12, and disassemble the needle 15. When installing, rotate the fixed seat 14 in the opposite direction to connect it with the liquid outlet pipe 13, and complete the installation. This installation method makes it difficult for the needle 15 to fall off and cause injury. Similarly, the needle cylinder 1 and the connecting seat 2 are separated by this method for cleaning and maintenance.
