The output tube 8 is connected to the body 1. The lower end of the output tube 8 is movably connected to the movable tube 15 for mounting needles. The injection angle of different types of needles can be adjusted by rotation. A sealing plug 9 is movably connected to the inner side wall of the movable tube 15 to block the movable tube 9 and enhance the sealing performance. The sealing plug 9 is located at the lower end of the movable tube 15. A protective cap 14 is movably connected to the side surface of the movable tube 15 to provide additional protection and dust prevention. The protective cap 14 covers the sealing plug 9. The side surface of the output tube 8 is provided with a protrusion to cooperate with the rotating groove, so that the movable tube 15 can rotate relative to the output tube 8.

[0024] The inner wall of the movable tube 15 is provided with a rotating groove for engaging with a protrusion, allowing the movable tube 15 to rotate relative to the output tube 8. The protrusion is located inside the rotating groove, and a sealing ring 16 is provided at the connection between the movable tube 15 and the output tube 8 to ensure a tight seal and prevent veterinary drug leakage. A piston 7 is movably connected inside the cylinder body 1, used to compress the veterinary drug by pushing the push rod 5, generating pressure to make the veterinary drug flow out. A push rod 5 is fixedly connected inside the piston 7 to push the piston 7 to move within the cylinder body 1. A support plate 6 is fixedly connected to the side surface of the push rod 5 to ensure that the piston 7 does not tilt or get stuck during movement. Both the support plate 6 and the push rod 5 are located within the movable tube 1. Between the plug 7 and the pad 10, the upper end of the push rod 5 is fixedly connected to the pad 10 for direct pushing by the operator. The front and rear surfaces of the pad 10 are fixedly connected to the positioning pins 11 for cooperating with the positioning holes 4 to fix the position of the blocking plate 3 and prevent the blocking plate 3 from moving during the pushing process. The side surface of the cylinder 1 is fixedly connected to the limiting block 12 for supporting the movement of the blocking plate 3. The limiting block 12 is located at the front and rear of the cylinder 1. The front surface of the limiting block 12 is provided with a limiting groove 13 for locking the blocking plate 3 and preventing the blocking plate 3 from moving during the injection process. The limiting groove 13 is located directly below the blocking plate 3. The top plate 2 is located above the cylinder 1 and covers the limiting block 12.

[0025] Working principle: First, veterinary medicine is drawn into the syringe through the output tube 8 and movable tube 15 of the syringe body 1, and then drawn in by the movement of the push rod 5 and piston 7. The push rod 5 is then fixed in place by the positioning hole 4 on the baffle plate 3 and the positioning pin 11 on the pad 10 above the push rod 5, preventing movement and leakage of the medicine. Simultaneously, the sealing plug 9 is installed at the lower end of the movable tube 15 for further sealing. Then, the cap 14, along with the sealing plug 9 and movable tube 15, is used for sealing and protection, allowing the syringe to be stored for a long time. When the syringe needs to be used, the cap 14 is removed, the sealing plug 9 is opened, and the baffle plate 3 is moved from the positioning pin 11 and its position adjusted. The stop plate 3 is fixed in the limiting groove 13 inside the limiting block 12, so that it will not interfere with the injection process of veterinary drugs. The operator pushes the pad 10 into the cylinder 1. Since the pad 10 is fixedly connected to the push rod 5, the push rod 5 will also move accordingly. The side surface of the push rod 5 is fixedly connected to the support plate 6, which ensures that the piston 7 can move stably in the cylinder 1. As the piston 7 moves, the veterinary drugs inside the cylinder 1 will be compressed and pressure will be generated. Under the action of pressure, the veterinary drugs will flow out through the output pipe 8. Since the movable pipe 15 is rotatably connected to the bottom of the output pipe 8, when the curved needle is installed on the movable pipe 15, the injection angle of the curved needle can be adjusted to adapt to different injection needs.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
