본 고안은 드라이버에 관한 것으로, 특히 스크류를 박거나 뺄때 사용하는 드라이버의 외면에 돌기를 형성하고 이에 장공이 끼워지며 손잡이 하단과의 사이에 스프링이 탄지된 원통형 가이더의 끝단에 절취홈을 형성하여 탄성을 갖도록 함으로써 드라이버로 스크류를 돌릴때 이의 두부 외주연이 드라이버의 가이더에 삽입되어 안정된 회전이 이루어져 조이거나 풀때 불편을 덜도록한 드라이버에 관한 것이다.The present invention relates to a driver, in particular, forming a projection on the outer surface of the driver used when screwing or removing the screw is inserted into the long hole, and the cutting groove is formed at the end of the cylindrical guider spring-tight between the lower end of the handle and elastic When the screw is turned by a screwdriver, the head outer periphery of the head is inserted into the guider of the screwdriver so that a stable rotation is achieved, thereby reducing the inconvenience of tightening or loosening the screw.

종래에는 스크류를 목재나 얇은 알루미늄판상에 나사 조임할때나 박힌 상태의 스크류를 풀고자할때에는 드라이버를 스크류의 두부에 형성한 요홈에 끼운 상태에서 회전하도록 하였으나 스크류를 눌러주는 힘과 드라이버를 회전시키는 힘을 동시에 작용하여야 하고 스크류의 회전 중심과 힘의 중심이 일치하지 않으면 드라이버가 요홈에서 이탈하게 되는 경우가 종종 발생하였다.Conventionally, when screwing the screw on a wood or thin aluminum plate, or to loosen the screw in the embedded state, the screwdriver is rotated in the groove formed in the head of the screw, but the screw pressing force and the screwdriver are rotated. If the force must be applied simultaneously and the center of rotation of the screw and the center of force do not coincide, the driver often breaks out of the groove.

그리고 특히 목재등에 박힌채 오랜 시간이 경과한 스크류를 풀고자 할때에는 녹이 슬거나 하여 드라이버가 이탈하게 되는 경우가 많았다.In particular, when trying to loosen the screw after a long time in the wood, etc., the driver was often dislodged due to rust.

이와같은 종래의 단점을 보완하기 위한 본 고안은 드라이버의 외면에 돌기를 형성하고 이에 장공이 끼워지며 손잡이와의 사이에 탄지된 스프링의 탄성을 받는 원통형 가이더의 끝단에 다수의 절취홈을 형성하여 자체 탄성을 갖도록하여 드라이버를 스크류의 홈에 끼울때 스프링의 탄성을 받는 가이더에 스크류 두부의 외주연이 삽입되도록 함으로써 드라이버를 돌릴때 힘의 중심과 회전 중심이 항상 일치하여 드라이버가 이탈하는 현상을 방지하도록 한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention to compensate for the above disadvantages is formed by forming a plurality of cutout grooves at the end of the cylindrical guider which is formed with a projection on the outer surface of the driver and the long hole is inserted therein and the spring elasticity between the handle and the self When the screwdriver is inserted into the groove of the screw, the outer periphery of the screw head is inserted into the guide which receives the elasticity of the spring when the screwdriver is inserted into the groove of the screw. If it is described in detail by the accompanying drawings as follows.

드라이버(1)의 외면에 돌기(1-1)를 형성하고, 이에 장공(2-1)이 끼워지며 손잡이(1-2)와의 사이에 탄지된 스프링(3)의 탄성을 받고 측벽의 걸림턱(2-4)이 구비된 상하 이동용 경사공(2-3)에 캡(4)의 돌부(4-1)가 끼워져 상하로 이동하도록한 원통형 가이더(2)의 끝단에 다수의 절취홈(2-2)을 형성하여 드라이버(1)의 끝단에서 일정한 길이가 항상 돌출되도록 삽입하여 구성한 것이다.The protrusion 1-1 is formed on the outer surface of the driver 1, and the long hole 2-1 is fitted therein, and the elasticity of the spring 3 held between the handle 1-2 is received and the latching jaw of the side wall. A plurality of cutout grooves 2 are provided at the end of the cylindrical guider 2, in which the protrusions 4-1 of the cap 4 are fitted in the up-and-down movement inclined holes 2-3 provided with (2-4). -2) is formed by inserting so that a certain length always protrudes from the end of the driver (1).

미설명부호 5는 스크류, 5-1은 스크류의 두부, 6은 목재 또는 알루미늄판이다.Reference numeral 5 is a screw, 5-1 is the head of the screw, 6 is a wood or aluminum plate.

이와같은 본 고안은 드라이버(1)의 돌기(1-1)에 장공(2-1)이 끼워지고 손잡이(1-2)와의 사이에 스프링(3)이 탄지되어 이의 탄성에 의해 일정 간격을 왕복동하는 원통형 가이더(2)의 끝단은 드라이버(1)의 끝단에서 스크류(4)의 두부(4-1) 두께 만큼은 항상 돌출되도록하고, 스크류(4)를 목재나 얇은 알루미늄판(5) 등에 나사조임할 때에는 스크류(4)를 목재나 얇은 알루미늄판(5) 등에 나사조임할때에는 스크류(4)의 두부(4-1)가 가이더(2)의 끝단에 삽입되도록하며 이때 가이더(2)의 끝단에 형성한 다수의 절취홈(2-2)에 의하여 약간 벌어지거나 오므라들면서 스크류(4)의 두부(4-1)가 안정되게 삽입된후 돌부(4-1)가 걸림턱(2-4)에 걸린 캡(4)을 살짝 밀어주어 경사공(2-3)을 따라 내려오면서 가이더(2)의 끝단이 스크류(4)의 두부와 밀착되게 한다.The present invention is such that the long hole (2-1) is fitted to the projection (1-1) of the driver (1) and the spring (3) is held between the handle (1-2) to reciprocate a certain distance by its elasticity The end of the cylindrical guider (2) to always protrude as much as the thickness of the head (4-1) of the screw (4) at the end of the driver (1), screwing the screw (4) to wood or thin aluminum plate (5) When screwing the screw (4) to the wood or thin aluminum plate (5), etc., the head (4-1) of the screw (4) is inserted into the end of the guider (2), at the end of the guider (2) The head 4-1 of the screw 4 is stably inserted while being slightly opened or retracted by the plurality of cutout grooves 2-2 formed, and then the protrusion 4-1 is placed on the catching jaw 2-4. Push the jammed cap (4) slightly so that the end of the guider (2) is in close contact with the head of the screw (4) while descending along the inclined hole (2-3).

그리고 스크류(4)의 두부(4-1)의 크기에 따라 스프링(3)의 탄성을 받으며 가이더(2)가 일정간격을 이동하면서 안정되게 삽입되도록 함으로써 사용자가 손잡이(1-2)를 이용하여 드라이버(1)를 회전시켜 스크류(4)를 목재나 얇은 알루미늄판등에 나사조임하거나 풀때 회전중심과 힘의 중심이 항상 일치하도록 하여 드라이버(1)가 이탈되는 경우를 방지하도록 하고 드라이버(1)에 가해지는 힘이 정확히 스크류(4)로 전달되어 적은 힘으로도 안정된 작업을 행할수 있는 것이다.In addition, the user receives the elasticity of the spring 3 according to the size of the head 4-1 of the screw 4 and the guider 2 is stably inserted while moving a predetermined interval so that the user can use the handle 1-2. Rotate the driver 1 so that the center of rotation and the center of force always coincide with each other when screwing or loosening the screw 4 to wood or a thin aluminum plate to prevent the driver 1 from being dislodged. The force applied is exactly transmitted to the screw (4) is able to perform a stable operation with a small force.
