Disclosed is a disposable high-precision safe microsyringe, comprising a pushrod (1), a rubber plug (2) and a barrel (3), wherein the pushrod (1) and the rubber plug (2) are fitted with each other and inserted from an upper end of the barrel (3)； a lower end of the barrel (3) is fitted with a needle body (8), the lower end of the barrel (3) is provided with a needle hub locating sleeve (6), a needle hub (5) is fitted in the needle hub locating sleeve (6), and one end of the needle body (8) is fixed to the needle hub (5)； and the pushrod (1) drives the needle hub (5) to rotate to be loosened and retracted, and simultaneously draws the needle body (8) into the barrel (3) and bends the needle body (8) to be locked in the barrel (3). By means of providing the needle hub (5), the needle body (8) is fixed to the needle hub (5), and the needle hub (5) is fitted with the rubber plug (2). After injection is completed, the needle body (8) is driven by the plunger (1) to be pulled back into the barrel (3) along with the needle hub (5), the rubber plug (2) makes the needle body (8) be not coaxial with the barrel (3), and the pushrod (1) is further pushed forwards such that the needle body (8) is bent and destroyed inside the barrel (3), thereby realizing safety and eliminating reuse. The present invention is ingenious in design and is powerful； and the fitting of the rubber plug (2) and the needle hub (5) further realizes the function of exhausting the air inside the barrel (3) before an agentia is extracted.La présente invention concerne une microseringue sûre jetable de haute précision, comprenant une tige de poussée (1), un bouchon en caoutchouc (2) et un cylindre (3), la tige de poussée (1) et le bouchon en caoutchouc (2) étant ajustés l'un à l'autre et insérés depuis une extrémité supérieure du cylindre (3)； une extrémité inférieure du cylindre (3) est ajustée à un corps d'aiguille (8), l'extrémité inférieure du cylindre (3) est munie d'un manchon de localisation de moyeu
