New description: [New technical field] This creation is about the protection device for injection syringes, especially for easy assembly and safe use to avoid the protection of the syringe. Injection for infection [Prior Art] - The protection device for injection syringes, such as the United States:: (4) has a syringe with a syringe, 2 inside the syringe, and is placed in the syringe. a screwing portion at one end, a needle group that can be screwed to the screwing portion, and a sleeve that is sleeved on the outside of the needle group to protrude. When the main needle is used, the injection is placed in the second injection: after the two needles are screwed into the screw, the outer tube is directed toward the syringe: private: 'make the needle When the group protrudes from the outer cover tube _ end, the cup can be pushed and pushed, and the injection medicine is injected through the screwing portion and the needle group. However, when the above-mentioned protective device for the syringe is assembled, the needle set and the screwing portion need to be screwed together first. The _W^ is very time-consuming in assembling, and after the end of the squeegee injection, it must be at the heart. The gentleman, to cancel the screwing of the needle group and the screwing part, is inconvenient. [New Content] This creator has developed the original creation in view of the fact that the Shangcheng 4 # μ protection device was actively engaged in research and development, in order to improve the above-mentioned .^, 'broken bond and efforts.
