Detailed Description

For the purpose of the present invention; technical solutions and advantages will be more clear, and the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-4, the utility model provides a safety infusion needle, which comprises a needle tube 1, wherein one end of the needle tube 1 is fixedly connected with an infusion needle 11, the other end of the needle tube 1 is fixedly connected with an infusion tube 8, one side of the outside of the needle tube 1 is fixedly provided with a push plate 6, and the outside of the infusion needle 11 is provided with a protective sleeve 3 for wrapping the infusion needle;

one side of the protection sleeve 3 is provided with a sliding groove 10 used for being matched with the push plate 6 to slide along the axial edge of the protection sleeve, the protection sleeve 3 is provided with a rotary clamping groove 2 on the side wall of one end close to the limiting sleeve 9, and the sliding groove 10 is communicated with the rotary clamping groove 2.
