The present invention discloses a disposable safety self-destruction insulin needle. The invention uses a sleeve-connected linkage structure and realizes an instant reset of the safety sleeve by means of the spring located in the middle axis so as to ensure that the needle tube is not exposed and preferably realizes a tilting and deflection of the self-destruction pressure base due to a plurality of flexible plates unevenly distributed on the inner wall in the needle base so as to finally ensure that the insulin needle cannot be used a second time, in so doing the safety self-destruction operation of the insulin needle is realized.
