The present invention is dedicated to a new automated hair transplanter that can further contribute to a safe and convenient transplantation by not only allowing free movement in a three-dimensional space when performing a procedure using an automated hair transplanter, but also preventing the rearward pushing of the transplanter that appears during tacking. It relates to a joint arm mechanism. In other words, the invention is a multi-joint arm mechanism (A) for exclusive use of an automated hair transplanter, comprising: a lower operating arm 210 capable of primary joint movement on an upper portion of the fixing block 201； An intermediate operating arm 220 capable of secondary joint movement at the end of the lower operating arm 210； A graft fixing member 230 capable of performing a third joint motion at the end of the intermediate operating arm 220； A lower ball joint joint coupling portion 240 and an upper ball joint joint coupling portion 250 respectively configured above the intermediate operating arm 220 under the lower operating arm 210； A joint movement temporary control device 300 for temporarily stopping all joint movements including the first joint movement, the second joint movement, and the third joint movement between the lower operation arm 210 and the intermediate operation arm 220 is included. The intermediate hinge-type joint coupling portion 260； It consists of a balance maintaining weight 400 for preventing the imbalance of the mechanism due to the weight is shifted to the outer rear of the lower operating arm 210；본 발명은 자동화 모발 이식기를 이용한 시술 작업시 3차원 공간에서의 자유로운 움직임이 가능할 뿐 아니라 시침시 나타나는 식모기의 후방밀림현상까지 방지하여 안전하고 편리한 이식작업에 더욱 기여할 수 있는 새로운 자동화 모발 이식기 전용 다관절 아암기구에 관한 것이다.즉 발명은 자동화 모발 이식기 전용 다관절 아암기구(A)에 있어서, 고정블럭(201)의 상부에 1차관절운동이 가능한 하부작동아암(210)； 상기 하부작동아암(210)의 끝에 2차관절운동이 가능한 중간작동아암(220)； 상기 중간작동아암(220)의 끝에 3차 관절운동이 가능한 이식기고정부재(230)； 상기 하부작동아암(210)의 하부 상기 중간작동아암(220)의 상부에 각각 구성되는 하부볼조인트관절결합부(240)와 상부볼조인트관절결합부(250)； 상기 하부작동아암(210)와 중간작동아암(220) 사이에서 1차관절
