Safety drop infusion/transfusion set capable of preventing recovered hypodermic needle from being pushed out, including: a sleeve slidably fitted on an infusion/transfusion catheter, a locating flange being formed on inner face of the wall of bottom end of the sleeve; and a needle holder formed with an axial tunnel. A top section of the needle holder is formed as a seat body for fitting with a hypodermic needle. A bottom section of the needle holder is formed as a connecting section for tightly fitting with the infusion/transfusion catheter. When downward pulling the infusion/transfusion catheter, the needle holder is drivingly retracted and latched with the locating flange of the sleeve. The hypodermic needle along with the needle holder is retracted and hidden in the sleeve. Therefore, the hypodermic needle recovered in the sleeve is prevented from being again pushed out of the sleeve.
