The beneficial effects of the invention are as follows：Each tensioning pole wire is fixed on the tensioning runner, and rotation tensioning runner is tightened up Tensioning pole wire, may be such that each pin knot is close to each other, because the exterior ring cap is isometric with the inner ring neck and common at them Have dislocation on axis, when each pin knot is close to each other, an exterior ring cap for pin knot is closely set in the inner ring of adjacent pin knot On neck, i.e. tightening up with tensioning pole wire, each pin knot joins end to end and is closely set-located；Now needle body split is completed simultaneously Keep fixing, can smoothly puncture blood vessel and be infused；After being fixed in acupuncture treatment and by syringe needle, rotation tensioning runner unclamps tensioning Silk, under the flowing of liquid, each pin knot is separated from one another, and now the needle body becomes soft, can be with vascular bending without pricking Blood trouble pipe.

The needle body of the invention has double wall, and quality is hard after split, can smoothly puncture tough and tensile vascular wall, therefore It is particularly suitable for the biological rescue of large-scale pet treat and field；When infusing animal due to syringe needle can deformation, even if Animal struggles without syringe needle from Ink vessel transfusing puncture blood vessel is worried, substantially increases transfusion efficiency and reduces unexpected generation, to rescue Help and striven for the quality time.

Preferably, the internal perisporium of each inner ring neck is frosting；When liquid flows out from the needle body, liquid and the mill There is larger friction in sand face, liquid will drive each pin knot away from needle stand, and promote opening for pin knot, and then soften syringe needle.

Preferably, two pin knot homopolar-repulsions that each pin knot is made by permanent-magnet material and arbitrarily closed on；With It is easy to each pin knot after tensioning pole wire unclamps to be separated two-by-two because homopolarity repels, and then the effectively flexibility of increase syringe needle.

Preferably, scribbling indicateing arm on the tensioning runner；In order to the tensioning shape of the needle body can be apparent from State.
