[0002] The emergence of syringes is an epoch-making revolution in the field of medical devices. The process of extracting and injecting gas or liquid with a needle is called injection. The syringe consists of a syringe with a small hole at the front end and a matching piston core rod. It is used to inject a small amount of liquid or gas into or extract it from areas that are inaccessible by other methods. 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] The existing rubber plugging technology adopts the direct forced insertion method, which is inserted into the syringe tube from top to bottom. The rubber plug is deformed during the process, and the deformed rubber plug has great friction with the syringe tube wall, which eventually causes the insoluble rubber plug microparticles to fall off due to irregular friction, which seriously poses an unsafe risk. Therefore, a new technical solution is needed to solve this problem. Summary of the invention
