[0002] A syringe is a common medical device, mainly used to inject liquid medicine or draw liquid. The syringe consists of a syringe with a small hole at the front end and a matching piston core rod. When the core rod is pulled out, the liquid or gas is sucked from the small hole at the front end of the syringe, and when the core rod is pushed in, the liquid or gas is squeezed out.

[0003] According to the disclosed extended veterinary syringe (publication number: CN 204049921 U), it includes a syringe with a small hole at the front end and a piston core rod matched therewith, a needle latex is provided at the lower end of the syringe, an injection hose is connected to one side of the syringe, an observation window is provided at the upper end of the syringe, the piston core rod is inserted into the syringe, the upper end of the piston core rod is connected to the piston shaft, the upper end of the piston shaft is equipped with a piston handle, and the upper end of the syringe is equipped with an injection handle. The veterinary syringe of this utility model is for veterinary use, the injection volume is large, and the animals are difficult to control, which will waste the liquid medicine, so an injection hose is configured, and the injection handle can be reused because it is not contaminated by the liquid medicine. A force rod is provided at the lower end of the injection handle, which has strong pushing and pulling and good stability, and is targeted at different types of animals. The above application cooperates with each other through components such as the syringe, needle latex and piston shaft, which makes it difficult to safely vaccinate animals, resulting in animals attacking staff during vaccination and injuring staff, which needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide an extended veterinary syringe, which realizes the movement of the handle through the cooperation of the extrusion force of the staff with the components such as the piston rod, the handle and the needle, thereby driving the movement of the piston rod, and the movement of the piston rod drives the movement of the plunger. The movement of the plunger will squeeze the vaccine inside the syringe, so that the vaccine enters the animal's body through the needle, so that the staff can inject the vaccine to the animal at a long distance, thereby protecting the safety of the staff, and solving the existing problems.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model is an extended veterinary syringe, comprising a first injection tube, one end of the first injection tube is threadedly connected to the second injection tube, the end of the second injection tube away from the first injection tube is threadedly connected to the third injection tube, the end of the third injection tube away from the second injection tube is threadedly connected to the fourth injection tube, the end of the fourth injection tube away from the third injection tube is threadedly connected to a fixture port, a piston rod passes through the side of the fixture port, one end of the piston rod is fixedly connected to a handle, the end of the piston rod away from the handle is fixedly connected to a plunger, and the circumferential surface of the first injection tube is provided with scale lines.

[0007] Furthermore, one end of the first injection tube is threadedly connected to a syringe port, and a needle is arranged on the side of the syringe port. Such a design can facilitate the replacement of the needle.

[0008] Furthermore, the circumferential surface of the second injection tube is provided with an external thread, and the inner wall of the second injection tube is provided with an internal thread. Such a design can facilitate the disassembly and assembly of multiple needle tubes.

[0009] Furthermore, the capacities of the first injection tube and the fourth injection tube are equal. Such a design can control the amount of vaccine according to the sizes of different animals.

[0010] Furthermore, the circumferential surface of the syringe port is provided with threads, and the inner wall of the fixture port is provided with threads. Such a design can facilitate disassembly and installation.

[0011] The utility model has the following beneficial effects:

[0012] 1. The utility model realizes the movement of the handle through the cooperation between the extrusion force of the staff and the components such as the piston rod, the handle and the needle, thereby driving the movement of the piston rod, and the movement of the piston rod drives the movement of the plunger. The movement of the plunger squeezes the vaccine inside the syringe, so that the vaccine enters the animal's body through the needle, so that the staff can vaccinate the animal at a long distance, thereby protecting the safety of the staff.

[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
