A safe blood sampling needle comprises a U-shaped sleeve (1), a T-shaped blood sampling core (12), a G-shaped safety protector (11), and a spring (17). The G-shaped safety protector (11) is provided with a guide core position (6), the spring (17) is mounted at an external diameter of the guide core position (6), and the T-shaped blood sampling core (12) is mounted at an internal diameter of the guide core position (6) of the G-shaped safety protector (11). The U-shaped sleeve (1) is mounted on the G-shaped safety protector (11), an arched step (4) is disposed at an inner end of the U-shaped sleeve (1) and stops a back arch abutment (13) of the T-shaped blood sampling core (12), and the back arch abutment (13) controls the spring (17) to form a static pressure. When the U-shaped sleeve (1) is pressed, the arched step (4) interferes with the back arch abutment (13), and meanwhile, the spring (17) bounces the T-shaped blood sampling core (12) together with a needle head (16) to an internal space (18) of the U-shaped sleeve (1). The needle head (16) is not exposed before and after use of the safe blood sampling needle, which achieves the purpose of safety for not injuring a user or a patient due to a use fault and being harmless to the society after use. Besides, the present invention is also a new technical solution suitable for automatic production.Aiguille de prélèvement sanguin de sécurité comprenant un manchon en forme de U (1), un noyau de prélèvement sanguin en forme de T (12), une protection de sécurité (11) en forme de G, et un ressort (17). La protection de sécurité (11) en forme de G est pourvue dune position (6) de noyau de guidage, le ressort (17) est monté au niveau dun diamètre externe de la position (6) de noyau de guidage, et la position du noyau de prélèvement sanguin en forme de T (12) est monté au niveau dun diamètre interne de la position (6) de noyau de guidage de la protection de sécurité (11) en forme de G. Le manchon (1) en forme de U est monté
