In view of this configuration, the needle 4, the casing 2 having the needle needle 2a into which the needle 4 is fitted at the front end, and the flange 2b formed at the rear end thereof, A piston 3a sliding along the inner wall of the casing 2 is coupled to the front end and consists of a rod 3 to which the crimping portion 3b is attached to the rear end. Throughout this specification, the front end refers to the injection needle 4 side and the rear end refers to the piston 3a side. Disposable syringes having such a structure do not need to be sterilized because they are discarded after one use. 1B is a cross-sectional view showing a conventional continuous syringe. In this configuration, the chemical liquid injection portion 6a is formed at the front end and the chemical liquid injection portion 6a is continuously injected through the hose 9, and the casing 6 having the handle portion 6b is formed at the rear end, and the chemical liquid injection portion ( A needle (7) inserted into the 6a), a rod (7) to which the piston (7a) sliding along the inner wall of the casing (6) is coupled to the front end and the crimp (7b) is attached to the rear end; A stopper 8 is screwed to the rear end of the casing 6 to guide the longitudinal movement of the rod 7, and is sandwiched between the stopper 8 and the crimping portion 7b. It consists of a spring 10 that pushes 7b back to its original position. The continuous syringe of this configuration has the advantage of shortening the inoculation time because it can be continuously injected to several livestock.

Since these disposable syringes or continuous syringes are not all equipped with a separate marking device, it is very difficult to discriminate between inoculated live animals and inoculated live animals when injecting several livestock at once. Korean patent application No. 97-15519 filed by the applicant of April 25, 1997 to solve this problem is disclosed a syringe for livestock equipped with a marking device. It has a structure that can identify the live animals injected by installing a marking device in a continuous syringe configured to store the disposable syringe in the casing and then continuously supply the chemical liquid through the hose.

In the conventional livestock syringe having such a configuration, there is a problem in that the manufacturing cost increases because the structure of the marking device is quite complicated and a plurality of valves are employed.

The present invention devised to solve such a problem is to provide a marking device having a simple structure injectable livestock syringe which can easily identify the livestock injected by attaching to the body or handle of the syringe.
