Abstract

핸드 그라인더가 개신된다. 개시된 핸드 그라인더는, 가공대상물의 표면을 연마하기 위한 연마재(10)를 구비한 핸드 그라인더에 있어서, 일측에 연마재(10)가 부착되고 타측에 요홈(18a)이 형성된 육각샹크(18)가 구비된 홀더(11); 상기 육각샹크(18)를 일측에 수용하며, 타측은 그라인더본체(12)의 축(12a)이 결합되는 커플링몸체(13); 상기 커플링몸체(13)의 외주면 일측을 감싸면서 슬라이드식으로 이동가능하며 탄성적으로 복귀하는 슬리브(15); 일측은 상기 육각샹크(18)의 끝단부에 지탱되고 타측은 핸드그라인더본체(12)의 축(12a)과 연결되는 커플링몸체(13)의 내면 나사부(13a)에 지탱되어 탄성력을 가하는 탈착스프링(14); 상기 커플링몸체(13) 내부에 수용홈(20)을 형성하고 육각샹크(18)의 요홈단부(18c)를 눌러주는 오(O)링(19); 상기 슬리브(15)의 전후 동작에 따라 상기 육각샹크(18)의 요홈(18a)에 안착되거나 또는 이탈하면서 상기 육각샹크(18)를 고정시키거나 해제하기 위한 볼(16); 커플링몸체(13) 외측에 결합된 소켓(30)과 상기 슬리브(15) 사이를 빈틈없이 막으면서 고정되는 카바(40); 를 포함한다. 이에 따라, 연마홀더를 커플링에 장착한 후 확실히 연마홀더를 고정시킬 수 있는 구조로 구비되어 연마작업시 연마홀더가 이탈되는 문제를 근원적으로 차단할 수 있으며, 원터치 방식으로 연마홀더를 교체할 수 있어서 연마작업의 효율을 현저히 상승시킬 수 있다.
