The subject innovation is to seat the syringe to the gun, the more reliable, depending on the size or length of the injector to move the syringe to the fixed and to the support position, and removal is possible in the case by a simple operation, and to mount the syringe It can be a drug on the jig for a syringe fixing of the automatic injection device so that its configuration is adapted gun to cause the drug is injected in accordance with the selected mode, is connected to the main body and the main body to select and activate the mode, by a screen touch operation the gun is gun-and-pusher for pushing force a piston rod of a syringe by a push of the irradiation button is provided on and to secure the syringe to the body of the front upper injector holder, the rear side of the injector holder is formed in the gun handle that is provided, the pusher end is coupled able to work with a conveyance screw provided in the gun body portion . In the automatic drug infusion devices that are configured to be able to pre backward by the reverse rotation of the screw forward, and the jig body case to be fitted around the upper end slide in the groove formed along the body of the length direction Through the side of the jig body in the horizontal direction, and the middle portion and the both sides of the transfer screw is left handed and right-threaded portion formed Handle and which is provided on one side and the other side end of the feed screw, tightening sphere A pair of fixing jaws A and a fixing jaw B which are respectively coupled to the left screw portion and the right screw portion of the conveying screw and are symmetrical to each other and are fixed to the jig body at a lower side of the fixing jaws A and B, It is intended to cover the stopper and the stopper a B.본 고안은 건에 주사기를 장착할 때, 주사기의 크기나 길이에 따라 보다 안정적으로 주사기를 고정 및 지지할 수 있는 위치로 이동이 가능하고, 간단한 조작에 의해서 건에 착탈이 가능하고 주사기를 장착할 수 있도록 한 약물 자동 주입장치의 주사기 고정용 지그에 관한 것으로, 그 구성은 스크린 터치 조작에 의해 모드를 선택 및 작동시키는 본체와, 상기 본체와 연결되어 선택된
