3 : 칼날면 5 : 장방형 요입홈3: blade side 5: rectangular concave groove

5' : 요입홈 선단5 ': tip of recessed groove

본고안은 몸체 하단부가 "" 형의 칼날면으로 된 나사못에 있어서 칼날면 상단에 몸체 양면으로 장방형의 요홈을 삭설하여 나사못을 접할물에 틀어박을 때 생기는 칩(Chip)이 칼날면 사이의 요입홈을 거친후 장방형 요홈을 따라 신속히 외부로 배출되게 하므로서 나사못이 접합물에 손쉽게 박히도록된 고안에 관한 것이다.In this case, the lower part of the body "In the screw of the blade surface of the type, the chip formed when cutting the screw into the water to contact the screw by cutting the rectangular groove on both sides of the body on the upper surface of the blade, then goes through the recess groove between the blade surface According to the invention so that the screw is easily nailed to the joint by being quickly discharged to the outside.

종래의 나사못은 몸체 하단부가 요입홈이 반원형으로된 칼날면으로만 형성되어 있어 반원형 요입홈에서 생기 칩이 외부로 잘 빠지지 못해 나사못을 박을 때 힘이들고 신속하게 박을 수가 없었다.Conventional screws have a lower end of the body is formed only in the blade surface of the concave groove is semi-circular, so that the chip does not fall well to the outside due to the semi-circular concave groove was difficult to drive the screw quickly.

본고안은 이와같은 결점을 제거하고저 창안된 것으로서 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.The present invention removes these drawbacks and is described in detail by the accompanying drawings as follows.

몸체(1) 하단부(2)가 요입홈(4)이 형성된 "" 형의 칼날면(3)으로 된 것에 있어서 칼날면(3) 상단에 몸체 양면을 타격하거나 삭설하여 장방형 요입홈(5)을 형성하되 장방형 요입홈(5)의 선단(5')이 칼날면(3)의 상단에서부터 연설되도록 한 것이다.The lower part 2 of the body 1 has a recessed groove 4 formed therein. "In the blade surface (3) of the type to form a rectangular concave groove (5) by hitting or cutting both sides of the body on the blade surface (3) upper end, but the front end (5 ') of the rectangular concave groove (5) It was to be delivered from the top of (3).

이와같이 형성된 본고안은 나사못 몸체(1)를 접합물에 틀어박을 때 칼날면(3)에 절삭되며 생긴 칩이 요입홈(4)에 모아지면서 나사못 몸체(1)가 점차 삽입됨에 따라 점차 밀려서 요입홈(4)에서 상승된 침은 칼날면(3)의 상단에서부터 선단(5')이 연설된 장방형 요입홈(5)을 따라 신속하게 외부로 배출되기 때문에 나사못 몸체(1)가 신속하면서도 쉽게 박히는 것이다.In this way, the formed bill is gradually pushed as the screw body (1) is gradually inserted as the chip is cut into the blade surface (3) when the screw body (1) is screwed into the joint and the resulting chip is collected in the recess groove (4). The needle raised from the mouth groove 4 is quickly discharged to the outside along the rectangular indentation groove 5 where the tip 5 'is protruded from the top of the blade surface 3 so that the screw body 1 is quickly and easily driven. will be.

따라서 본고안은 칼날면에 반원형으로만된 종래의 것에 비해 칩의 배출상태가 양호하여 힘들이지 않고 신속하게 나사못을 박을 수 있는 매우 유용한 고안인 것이다.Therefore, this paper is a very useful design that can be screwed quickly and effortlessly because the discharge state of the chip is good compared to the conventional half-circle only on the blade surface.

Claims

In the lower end part 2 of the body 1, the recessed groove 4 and the blade surface 3 are formed, and the rectangular recessed groove 5 is formed on both sides of the upper body of the blade surface 3, but the tip 5 'is formed. Screw characterized in that the speech from the top of the blade surface (3).
