The opening and closing door 2 rotates to drive the arc block 4 to move. At this time, the arc block 4 will contact the syringe 3, and the syringe 3 can be pressed and fixed. When the syringe 3 is placed, the motor 7 starts and drives the threaded rod 8 to rotate. The threaded rod 8 rotates through the threaded groove on the surface to drive the bayonet groove 11 to move downward. The downward movement of the bayonet groove 11 drives the pressure rod 5 to move downward. The downward movement of the pressure rod 5 will spray the vaccine stored in the syringe 3 into the animal's body, and the vaccine can be automatically injected, so that the injection process can be completed quickly, reducing the time of manual operation, especially when dealing with a large number of animals, significantly improving work efficiency, thereby avoiding uneven pressing force and inaccurate injection position during manual injection, resulting in poor injection effect, and reducing human errors; The circumferential surface of the injection tube 3 contacts the rear portion of the arc block 4, and the arc block 4 is used to fix the position of the injection tube 3. The circumferential surface of the injection tube 3 contacts the inner wall of the housing 1. The circumferential surface of the threaded rod 8 is rotatably connected to the inner wall of the slide groove 9. The pressure rod 5 contacts the inner wall of the bayonet groove 11, and the bayonet groove 11 is used to push the pressure rod 5 to move downward. The circumferential surface of the injection tube 3 contacts the right side of the extrusion plate 13. When the syringe 3 is being inserted, the syringe 3 will come into contact with the squeezing plate 13 and generate an squeezing force on the squeezing plate 13, so that the squeezing plate 13 can move to the left. The squeezing plate 13 moves to the left, driving the sliding rod 12 to move and compressing its own spring. Then, when the syringe 3 completely enters the interior of the shell 1, the syringe 3 will be in the inner arc position of the squeezing plate 13. At this time, the sliding rod 12 is reset by the spring and drives the squeezing plate 13 to move, so that the position of the syringe 3 can be further fixed to avoid loosening or shaking during the injection process, thereby improving the stability of the injection process. At the same time, syringes 3 of different diameters can also be fixed, so that different models of syringes 3 can be replaced according to different medicines, which greatly improves the diversity of the use of the device.

[0017] Working principle: When the syringe 3 is placed, the motor 7 starts and drives the threaded rod 8 to rotate, and the bayonet slot 11 moves downward to drive the pressure rod 5 to move downward. The downward movement of the pressure rod 5 will spray the vaccine stored in the syringe 3 into the animal's body, and then the vaccine can be automatically injected, so that the injection process can be completed quickly, reducing the time of manual operation. When the syringe 3 is placed, the syringe 3 will be in the inner arc position of the extrusion plate 13. At this time, the sliding rod 12 is reset by the spring and drives the extrusion plate 13 to move, so that the position of the syringe 3 can be further fixed, thereby improving the stability during the injection process. At the same time, syringes 3 of different diameters can also be fixed, so that different models of syringes 3 can be replaced according to different medicines.

[0018] See also Figure 1-Figure 7 In another embodiment of the present invention, based on the above embodiment, the quantitative mechanism 14 includes a sensor metering bar 141, which is fixedly connected to the inner wall of the housing 1. The inner wall of the bayonet slot 11 is fixedly connected to a connecting block 142. The inner wall of the connecting block 142 is slidably connected to a moving rod 143 via a spring. The inner wall of the moving rod 143 is fixedly connected to a chamfering block 144. The inner wall of the housing 1 is fixedly connected to a slot 145. The inner wall of the housing 1 is slidably connected to an elastic rod 146 via a spring. The bottom of the elastic rod 146 is fixedly connected to a force-bearing plate 147. During the injection process, the bayonet slot 11 moves downward, driving the connecting block 142 to move downward. The downward movement of the connecting block 142 will drive the moving rod 143 to move downward. The downward movement of the moving rod 143 will drive the chamfering block 144 to move downward. When the chamfering block 144 moves to the groove position of the sensor metering bar 141, the moving rod 143 will move to the left by the spring. The movement of the moving rod 143 drives the chamfering block 144 to move, and then it can move to the inside of the groove of the sensor metering bar 141, and generate an electrical signal, which will then be transmitted to the motor 7, so that the injection of the vaccine can be stopped, thereby ensuring that the vaccine dose of each injection is accurate, avoiding excessive or insufficient doses due to improper manual operation, and ensuring that each animal can obtain appropriate immune stimulation, thereby improving the overall vaccination effect. When the injection is completed, the needle is manually replaced, and then the next animal is injected; The injection tube 3 contacts the inner wall of the slot 145 , and the elastic rod 146 is used to limit the injection tube 3 . The right side of the sensor metering bar 141 contacts the left side of the chamfered block 144 . The sensor metering bar 141 is electrically connected to the motor 7 . When the needle is inserted into the animal's body, the force plate 147 will first contact the animal's skin and generate an extrusion force on the force plate 147, causing the force plate 147 to move upward relative to the shell 1. The upward movement of the force plate 147 drives the elastic rod 146 to move upward relative to the shell 1 and compress its own spring. Then, the support provided by the force plate 147 and the reaction force provided by the elastic rod 146 can make it possible to gently touch the skin before the injection when the needle is inserted, so that the animal can gradually adapt to this process and avoid the sudden pain caused by the needle prick. This can reduce the animal's stress response and discomfort, especially when a large amount of injection is given, and can maintain the stability of the animal.

[0019] Working principle: During the injection process, the bayonet slot 11 moves downward, driving the connecting block 142 to move downward, and the moving rod 143 will move to the left through the spring. The movement of the moving rod 143 drives the chamfered block 144 to move, and then it can move to the inside of the groove of the sensor metering bar 141, and will generate an electrical signal, which will then be transmitted to the motor 7, thereby stopping the injection of the vaccine, thereby ensuring that the vaccine dose for each injection is accurate. When the needle is inserted into the animal's body, the force plate 147 will first contact the animal's skin, and can gently touch the skin before injection to allow the animal to gradually adapt to this process.

[0020] The disinfection mechanism 15 includes a fixing bar 151, which is fixedly connected to the bottom of the shell 1, the inner wall of the fixing bar 151 is rotatably connected to a rotating plate 152 through a torsion spring, the inner wall of the rotating plate 152 is fixedly connected to a round rod 153, the top of the force-bearing plate 147 is fixedly connected to an inclined bar 154, the front of the rotating plate 152 is fixedly connected to a protective plate 155, the top of the force-bearing plate 147 is fixedly connected to an oblique long plate 156, the bottom of the shell 1 is fixedly connected to a storage box 157, the inner wall of the shell 1 is slidably connected to a pressure rod 158 through a spring, the left side of the pressure rod 158 is fixedly connected to an oblique plate 159, the bottom of the shell 1 is fixedly connected to a retaining frame 1510, and the bottom of the shell 1 is fixedly connected to a water outlet pipe 1511; When the needle is inserted, the force-bearing plate 147 moves upward, driving the inclined bar 154 to move upward. During the upward movement of the inclined bar 154, it will contact the round rod 153 and push the round rod 153 backward through the inclined surface at the top of the inclined bar 154. The backward movement of the round rod 153 will drive the rotating plate 152 to rotate backward. The rotation of the rotating plate 152 drives the protective plate 155 to move, thereby releasing the protection of the needle at the bottom of the injection tube 3. When the injection is completed, the elastic rod 146 moves downward through the spring and drives the inclined bar 154 to move downward. The downward movement of the inclined bar 154 will cause the rotating plate 152 to reset through the torsion spring. The reset of the rotating plate 152 will drive the protective plate 155 to move, thereby protecting the needle, thereby effectively preventing the staff from being pricked by the needle, thereby ensuring their safety. The circumferential surface of the round rod 153 contacts the top of the inclined bar 154, the inner wall of the protective plate 155 contacts the injection tube 3, the inner wall of the retaining frame 1510 is slidably connected to the surface of the inclined long plate 156, and the inclined long plate 156 will push the inclined plate 159 to move during the movement. The storage box 157 is used to store disinfectant; During the injection, the force plate 147 moves and drives the oblique long plate 156 to move upward. During the upward movement of the oblique long plate 156, it will contact the oblique plate 159 and generate a rightward squeezing force on the oblique plate 159 through the oblique surface, causing the oblique plate 159 to move to the right. The movement of the oblique plate 159 to the right will drive the pressure rod 158 to move to the right. When the pressure rod 158 moves to the right, it will generate pressure on the inside of the storage box 157, and then before the needle is inserted, the disinfectant stored in the storage box 157 can be sprayed onto the surface of the animal's skin through the outlet pipe 1511, thereby effectively killing bacteria, viruses or other microorganisms, reducing the risk of infection caused by microbial contamination during the injection process, and automatically spraying the disinfectant to ensure that each vaccination follows strict hygiene standards and does not rely on manual operation.

[0021] Working principle: When performing an injection, the rotating plate 152 rotates to drive the protective plate 155 to move, thereby releasing the protection of the needle at the bottom of the injection tube 3. When the injection is completed, the rotating plate 152 is reset to drive the protective plate 155 to move, thereby protecting the needle, thereby effectively preventing the staff from being pricked by the needle. When performing an injection, when the pressure rod 158 moves to the right, it will generate pressure inside the storage box 157, and then before the needle is inserted, the disinfectant stored in the storage box 157 can be sprayed onto the surface of the animal's skin through the outlet pipe 1511. The disinfectant is sprayed automatically without relying on manual operation.
