The present invention relates to a pitch adjustment type auxiliary device for injecting drugs and more specifically, to a pitch adjustment type auxiliary device for injecting drugs in which a syringe is installed in order to inject predetermined amount of drugs by automatically adjusting the amount. The device according to the present invention is formed with a drug injection module (101) in which the syringe is held, and a transfer module (102) which transfers the drug injection module (101). The drug injection module (101) comprises: a supporting plate (11) which is horizontally extended a transfer handle (12a) which is installed for the syringe to be held by leaving a predetermined distance from the upper surface of the supporting plate (11) a first driving motor (M1) a first gear (13a) which is connected to the first driving motor (M1) and a second gear (13b) which is connected to the first gear (13a) and a transfer screw (14) which is rotated by driving the first driving motor (M1) and extended along the support plate (11) by being interlocked with the second gear (13b). The transfer module (102) comprises: a second driving motor (M2) a core member (16) combined with a shaft of the second driving motor (M2) a transfer pitch member (17) which is combined with the core member (16) as being transferrable and has pitches formed with predetermined intervals and a module fixing member (18) which is combined with the transfer pitch member (17) and fixed to the supporting plate (11). The drug injection module (101) is transferred by transferring the transfer pitch member (17). Transfer of the transfer handle (12a) is controlled by the first driving motor (M1).COPYRIGHT KIPO 2014본 발명은 피치 조절 방식의 약물 주입 보조 장치에 관한 것이고, 구체적으로 주사기가 장착되어 체내에 정해진 양의 약물이 자동으로 조절되어 주입될 수 있도록 하는 피치 조절 방식의 약물 주입 보조 장치에 관한 것이다. 본 발명에 따른 장치는 주사기가 거치되는 약물 주입 모듈(101)과 약물 주입 모듈(101)을 이동시키는 이동 모듈(102)로 이루어지고, 상기 약물 주입 모듈(101)은 수평으로 연장되는 받침 판(11) 받침 판(11)의 위쪽 표면에 일정 거리를 두고 주사기가 거치될 수 있도록 설치된 이동 죔쇠(12a) 및
