The plant growth regulator has the advantages of small mass, mild and smooth sex, fast growth, short propagation period, strong disease resistance and the like, and is selected as an animal model research object in a laboratory. By carrying out pharmacological, toxicological and tumor experiments and other various acute and chronic reaction experiments on rats or mice, the method has the advantages of obtaining the attention achievement accepted by the medical community, greatly promoting the progress and development of human medical level and benefiting mankind. In practice, the current administration modes of the animal model of the mice are gastric lavage administration, intraperitoneal injection, subcutaneous injection, tail vein injection and the like. The tail intravenous injection (also called as tail vein puncture) is the most important administration method, and compared with other administration modes, the method has the advantages of accurate and reliable pharmacological experiment results, closest to the human body administration mode, and capability of saving the dosage and the number of experimental animals. However, in practice, it has been found that since the tail vein is thin, the tail vein is buried deeply, and particularly, since the tail cuticle and vein of the rat are thin, successful puncture is very difficult, and particularly, the tail vein is square or bamboo-shaped, and the puncture administration success rate is very low. Thus, the experimenters, especially the beginners, need to spend a great deal of effort to practice the 'rat tail vein puncture', but still have high failure rate, waste of substances and time is caused, the problems plague basic and clinical testers, and the progress of related medical tests is hindered and delayed. It is therefore highly desirable to find a safer, more reliable method of venipuncture from the tail of the rat with a higher success rate. The semi-automatic puncture device for the tail vein successfully solves the problems. The needle feeding device has the characteristics of economy, practicality, stable structure, easy operation, high needle feeding success rate, difficult shifting and falling, accurate administration and the like. The technical device utilizes the characteristics of different tail parts and other body parts: the skin is exposed, regular convex-concave ring-shaped structures exist on the surface, the position of the needle head is calculated in a stepping mode through the hinged gear, angle adjustment is carried out, the needle is shot into the needle by means of shooting, and the needle head is accurately positioned, mechanically pierced into the needle and stably kept by the aid of the structure that the needle is successfully shot into the observation window is verified.
