Abstract

본 발명은 무침주사기에 관한 것으로서, 외주면에 원주방향으로 복수의 홀더부가 형성된 피스톤 샤프트와; 상기 피스톤 샤프트를 전후 슬라이드 가능하게 수용 지지하는 실린더 어셈블리와; 상기 실린더 어셈블리 내에 수용되어 상기 피스톤 샤프트의 둘레에 배치되되 반경방향으로 이동 가능하며, 상기 피스톤 샤프트의 후진 시 상기 복수의 홀더부에 삽입되는 복수의 볼과; 상기 실린더 어셈블리의 후단에 슬라이드 가능하게 결합되어, 상기 홀더부에 삽입된 볼에 대해 반경방향 이동을 차단하는 트리거 단부가 형성되며, 전진 슬라이드 시 상기 트리거 단부의 차단을 해제하는 트리거 버튼과; 상기 피스톤 샤프트를 전방으로 가압하는 제1탄성가압수단; 및 상기 트리거 버튼을 후방으로 가압하는 제2탄성가압수단을 포함하는 것을 특징으로 한다. 이에 의해, 구조를 단순화하여 제조가 간단하며 사용이 편리한 무침주사기를 제공할 수 있다.
