摘要：
An interface for an injection needle (4) of a medical syringe injector (1, 45), achieving the interface of the injection needle (4) formed by a cone head (7, 50) and a cone slope surface (20, 63) of an outer sleeve (2, 46) and a cone lip side (21) and a cone hole (22) of the injection needle (4), when the cone hole (22) of the injection needle (4) is plugged in the cone head (7, 50) of the outer sleeve (2, 46), the injection needle (4) is fixed on the cone head (7, 50) of the outer sleeve (2, 46), so that the purpose of preventing the tip of the injection needle (4) from swinging when the injection needle (4) sticks into the muscle or blood vessel of a human body is achieved so as to avoid causing operation errors； after the medical syringe injector (1, 45) is used, only the cone lip side (21), distant from the injection needle tip, of the injection needle (4) needs to be pinched flat, and the injection needle (4) can then be separated from the outer sleeve (2, 46) of the medical syringe injector (1, 45), the bacteria infected injection needle (4) can be placed in a collection box, and can also be drawn into a tool cavity (15, 58) of a core rod (3, 47) of the medical syringe injector (1, 45), the purpose of preventing contacting the injection needle tip in the operation process is achieved, so as to avoid bacteria infected injection needle (4) causing harm to the human body.La présente invention concerne une interface pour une aiguille d'injection (4) d'un injecteur à seringue médicale (1, 45), permettant d'obtenir une interface d'aiguille d'injection (4) formée par une tête conique (7, 50) et une surface de pente conique (20, 63) d'un manchon externe (2, 46) et un côté de lèvre conique (21) et un trou conique (22) de l'aiguille d'injection (4). Lorsque le trou conique (22) de l'aiguille d'injection (4) est enfiché dans la tête conique (7, 50) du manchon externe (2, 46), l'aiguille d'injection (4) est fixée sur la tête conique (7, 50) du manchon externe (2, 46), de
