The present invention provides a syringe protector, wherein the syringe may be used in scalp needles, butterfly needles or winged detained needles. The protector comprises a positioning tube, a first protection element, and a second protection element. The first and second protection elements are covered and positioned at an original position outside the positioning tube in an upper and lower configuration and connected at the rear ends, wherein the first protection element and the second protection element at the original position expose the needle of the syringe the first protection element and the second protection element are moved to a protection position from the original position along the positioning tube, in which the protection position shields the needle under the first and second protection elements. Furthermore, the front ends of the first and second protection elements at the protection position may be pressed with respect to each other and generate a unreleasable buckling relation through their buckles and buckling holes.一種注射針保護裝置,該注射針為頭皮針、蝴蝶針或帶翼留置針,該保護裝置包括一定位管以及呈上下位且後端相連的方式包覆定位於該定位管外部之一原始位置之第一保護件和一第二保護件;該原始位置之第一保護件和第二保護件使注射針之針體顯露;該第一保護件和第二保護件可沿著該定位管從上述原始位置移動至一保護位置,該保護位置之該第一保護件和該第二保護件遮蔽該針體;更進一步的,該保護位置之該第一保護件和該第二保護件的前端可相對壓合透過彼此的凸扣和扣合孔產生無法解除的扣合關係。1‧‧‧注射針2‧‧‧保護裝置12‧‧‧翼片13‧‧‧導管14‧‧‧針體20‧‧‧定位管21‧‧‧止擋部22‧‧‧微凸擋點23‧‧‧輔助部30‧‧‧第一保護件31‧‧‧第一板片311‧‧‧紋路32‧‧‧第一後端板33‧‧‧第一後側板34‧‧‧扣環35‧‧‧中位側板36‧‧‧缺口37‧‧‧滑扣板38‧‧‧導引緣39‧‧‧凸扣40‧‧‧第二保護件41‧‧‧第二板片42‧‧‧第二後端板43‧‧‧第二後側板44‧‧‧扣勾45‧‧‧扣合板46‧‧‧缺口47‧‧‧導引緣48‧‧‧承接槽491‧‧‧承接孔492‧‧‧扣合孔
