드라이버driver

본 고안은 나사를 조이거나 푸는데 사용하는 드라이버에 관한 것으로, 더 상세하게는 머리의 양쪽편에 보조 홈이 형성된 나사를 푸는데 적합하게 사용할 수 있도록 한 드라이버에 관한 것이다.The present invention relates to a screwdriver used to tighten or loosen a screw, and more particularly to a screwdriver that can be suitably used to loosen a screw having an auxiliary groove formed on both sides of the head.

도 1 은 종래의 드라이버의 사용상태 사시도이다.1 is a perspective view of a state of use of a conventional driver.

드라이버(A,B)는 나사(a)를 조이거나 푸는데 사용하는 것으로, 통상적으로 플라스틱재로 된 손잡이부(10)와 금속재로 된 몸통부(20)로 구성되며, 몸통부(20)의 팁부위가 +자형으로 된 것은 +자 드라이버(A)라 칭하고 몸통부(20)의 팁부위가 -자형으로 된 것은 -자 드라이버(B)라 칭한다.Drivers (A, B) is used to tighten or loosen the screw (a), it is usually composed of a plastic handle portion 10 and the metal body portion 20, the tip of the body portion 20 The + -shaped part of the part is called a + -shaped driver A, and the tip of the trunk portion 20 is --shaped.

그런데, 나사(a)를 자주 조이고 풀거나 규격에 맞지 않는 드라이버(A,B)로 억지로 체결하는 등으로 인하여 나사(a)의 머리에 있는 +자홈(a1) 또는 -자홈(a2)이 마멸되는 경우가 종종 있다. 이러한 경우 종래의 드라이버(A,B)는 무용지물이 된다.However, the + magnetic groove (a1) or-magnetic groove (a2) on the head of the screw (a) is abraded due to frequent tightening and loosening the screw (a) or forcibly tightening with a screwdriver (A, B) that does not conform There are often cases. In this case, the conventional drivers A and B become useless.

본 고안은 나사의 머리에 기존의 +자홈 또는 -자홈과 함께 보조 홈을 형성하는 한편, 사용중 나사의 +자 홈이나 -자홈이 마멸되었을 경우 보조 홈을 이용하여 나사를 푸는데 적합한 구조의 드라이버를 제공하는데 있다.The present invention forms an auxiliary groove together with the existing + magnetic groove or-magnetic groove on the head of the screw, and provides a screwdriver having a structure suitable for loosening the screw by using the auxiliary groove when the + magnetic groove or the-magnetic groove of the screw is worn out during use. It is.

본 고안은 머리에 +자홈(a1) 또는 -자홈(a2)과 함께 양쪽편에 보조 홈(a3)이 형성된 나사(a)를 체결하는데 사용하는 드라이버(C)에 있어서,The present invention is a screwdriver (C) used to fasten the screw (a) formed in the auxiliary groove (a3) on both sides with the + magnetic groove (a1) or-magnetic groove (a2) on the head,

상기 몸통부(200)를 크랭크형으로 절곡 형성함과 동시에 상기 보조 홈(a3)에 끼워질 수 있도록 상기 몸통부(200)의 팁부위에 ㄷ자형 돌기(210)를 형성한 것에 그 특징이 있다.The c-shaped protrusion 210 is formed on the tip portion of the torso 200 so that the torso 200 may be bent in a crank form and fitted to the auxiliary groove a3. .

이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 2 는 본 고안에 따른 드라이버의 사용상태 사시도이고, 도 3 은 본 고안에 따른 드라이버의 사용상태 단면도이다.Figure 2 is a perspective view of the state of use of the driver according to the present invention, Figure 3 is a cross-sectional view of the state of use of the driver according to the present invention.

도 2 에 도시한 바와같이, 본 고안에 따른 드라이버(C)는 나사(a)에 회전력을 크게 전달시킬 수 있도록 하기 위하여 몸통부(200)를 크랭크형으로 절곡시키고 몸통부(200)의 하단을 ㄷ자형으로 형성하여 나사(a)의 머리부 양쪽편에 형성된 보조 홈(a3)에 끼울 수 있도록 한 것이다.As shown in Figure 2, the driver (C) according to the present invention is to bend the body portion 200 in a crank form in order to transmit a large rotational force to the screw (a) and the lower end of the body portion 200 It is formed so as to be inserted into the auxiliary groove (a3) formed on both sides of the head of the screw (a).

한편, 나사(a)에 형성된 2개의 보조 홈(a3) 머리의 가장자리를 ㄷ자형으로 절개한 형태에며 서로 마주보는 위치에 있다.On the other hand, the edges of the head of the two auxiliary grooves (a3) formed in the screw (a) in the form of a c-shaped cut and are in a position facing each other.

따라서, 본 고안은 나사(a)의 머리에 있는 +자홈(a1)이나 -자홈(a2)이 마멸되었을 경우에 사용하여 나사(a)를 풀 수 있다.Therefore, the present invention can be used when the + magnetic groove a1 or the-magnetic groove a2 at the head of the screw a is worn out.

즉, 도 3 에 도시한 바와같이, 나사(a)가 임의의 부재에 조여진 상태에서 +자홈(a1) 또는 -자홈(a2)이 마멸되었을 경우에 본 고안에 따른 드라이버(C)를 사용하면 된다. 이때 드라이버(C) 하단의 ㄷ자형 돌기(210)를 나사(a)의 보조 홈(a3)에 끼운 다음 한손으로는 드라이버(C)의 손잡이부(100)를 잡고 다른 한손으로는 몸통부(200)를 돌리면 나사(a)가 풀리게 된다.That is, as shown in FIG. 3, the screw C according to the present invention may be used when the + magnetic groove a1 or the-magnetic groove a2 is worn out while the screw a is tightened to an arbitrary member. . At this time, insert the c-shaped protrusion 210 at the bottom of the driver (C) into the auxiliary groove (a3) of the screw (a), and then hold the handle part 100 of the driver (C) with one hand and the body part 200 with the other hand. Turn the screw to loosen the screw (a).

상술한 바와같이 본 고안에 따른 드라이버(C)는 보조 홈(a3)이 형성된 나사(a)를 푸는데 적합한 구조로 된 것으로, 나사(a)에 형성된 +자홈(a1)이나 -자홈(a2)이 마멸되었을 경우에 편리하게 사용할 수 있다.As described above, the driver C according to the present invention has a structure suitable for loosening the screw a having the auxiliary groove a3 formed therein, and the + magnetic groove a1 or the-magnetic groove a2 formed on the screw a is provided. It can be used conveniently when worn out.
