摘要：
An automatic drug injection device comprising - an external body (1； 100) extending along a longitudinal axis (X), - a syringe group (6； 106) placed in said external body (1； 100) and fixed thereto, said syringe group comprising a syringe (7； 107) containing a drug to be injected, a needle (7a； 107a) and plunger means (8； 108) that can slide axially and pivot with with respect to said external body (1； 100), - means for assembling (4； 104, 204) said device from a storage position to a first armed position to inject a first dose and at least a second armed position to inject a second dose, said assembly means being arranged at one end of the external body (1； 100), - first elastic means (10； 110) arranged between said assembly means (4； 104, 204) and said piston means (8； 108), said first elastic means being in compressed state when the d The device is in its storage position and is decompressed to push forward said plunger means (8； 108) and successively administering said first and said at least second dose, - a sliding sleeve (30； 130) arranged at the other end of said external body (1； 100) and limited to slide axially therein, as a result of a pressure exerted on its free end, in contrast to second elastic means (35； 135) disposed between said sliding cover (30； 130) and said external body (1； 100), between a sliding locking position, in which said cover slide (30； 130) is projected from said external body (1； 100) covering the needle (7a； 107a) of the syringe, and an activation position of the device, wherein said sliding sleeve (30； 130) is retracted in said outer body (1； 100) leaving the needle (7a； 107a) of the exposed syringe, said second elastic means (35； 135) being suitable to return said sliding sleeve (30； 130) to said locked position when said pressure action ceases, - impulse cam means sores (28； 128) operatively connected to said sliding cover (30； 130) and which can pivot axially in said external body (1； 100), - activation cam means (26, 27； 126,
