Abstract

본 고안은 드라이버로 나사를 죄고 풀 때 나사 윗부분의 홈이 덜 닳도록 모양을 낸 삼뿔나사(B-1)과 삼뿔나사(B-1)를 조이고 푸는 삼뿔드라이버(B-3)에 관한 것입니다.

Description

삼뿔나사와 삼뿔드라이버{omitted}
기존의 +나사 윗부분의 홈(A-1)은 (A-2)의 점선처럼 사각형 모양으로 홈이 파여져 있어서 +드라이버(A-3)으로 조이고 푸는 것을 반복하면 삼각형 모양으로 홈이 파여진 삼뿔나사(B-1)보다 더 빨리 윗부분의 홈이 닳았다.
드라이버로 나사를 조이고 풀 때 나사 윗부분의 홈이 덜 닳도록 만드는 것
삼뿔나사(B-1)은 (B-1)의 모양처럼 나사 윗부분에 홈이 파여져 있고 삼뿔드라이버(B-3)은 (B-3)처럼 드라이버 앞부분이 돌출되어 있다.
삼뿔나사 윗부분의 홈(B-1)은 (B-2)의 점선처럼 삼각형 모양으로 홈이 파여져 있어서 삼뿔드라이버(B-3)으로 조이고 푸는 것을 반복하면 사각형 모양으로 홈이 파여진 +나사(A-1)보다 윗부분의 홈이 덜 닳게 된다. 그래서 +나사(A-1)와 +드라이버(A-3)를 이용하는 곳에 삼뿔나사(B-1)과 삼뿔드라이버(B-3)을 이용하면 좋을 것이다.
(A-1)은 기존의 +나사 윗부분의 홈, (A-3)은 기존의 +드라이버
(B-1)은 삼뿔나사 윗부분의 홈, (B-3)은 삼뿔나사를 조이고 푸는 삼뿔드라이버
