Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the invention easy to understand, the invention is further explained below with reference to the specific embodiments, but the following embodiments are only the preferred embodiments of the invention, not all. Based on the embodiments in the implementation, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention. The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents and the like used in the following examples are commercially available unless otherwise specified.

Example (b):

as shown in fig. 1-3, a novel thread spring needle convenient to replace comprises a needle tube 1, a hexagonal rotor 3 is arranged at the front end of the needle tube 1, a thread ring 2 is arranged on the outer surface of the needle tube 1, a needle head 4 is slidably connected inside the hexagonal rotor 3, a buffer spring 6 is arranged at the rear end of the needle head 4, and a rear plug 5 is slidably connected at the rear end of the needle tube 1;

through the method of turning the screw thread, make the surface of needle tubing 1 be provided with the thread circle 2, when using the spring needle, only need to the spring needle rotatory screw up can, only need to rotate the spring needle to screw out when needing to be changed, again new spring needle change can, and back stopper 5 structure, make when producing the spring needle, only need to pack in syringe needle 4, buffer spring 6, back stopper 5 from the rear end of needle tubing 1 in proper order, thereby realize the production equipment to the spring needle, and through setting up hexagonal turn round 3, and the area that has improved the anterior segment makes the spring needle receive powerful striking and make and be difficult to damage, and adopt hexagonal turn round 3 can the convenience of customers better screw up the spring needle when using.

In other embodiments, the needle 4 is arranged in a T shape, and the diameter of the top opening of the hexagonal rotary head 3 is matched with the diameter of the outer surface of the upper end of the needle 4; through the T-shaped arrangement of the needle head 4, the problem that the needle head 4 is separated from the needle tube 1 when the needle head 4 is pushed to move by the elastic deformation of the buffer spring 6 is avoided
