본 고안은 원하는 방향으로 자유회전되는 드라이버에 관한 것이다. 종래에도 이와 유사한 드라이버가 있었으나 이는 그 구조가 극히 복잡하여 인가로 제공할 수 없는 결점이 있었으며 또 자유회전을 제어하는 제어부의 취약성으로 인하여 쉽게 고정이나는 결점이 있었던 것이다.The present invention relates to a driver that is free to rotate in the desired direction. In the related art, there was a similar driver, but the structure was extremely complicated, and there was a defect that could not be provided by the application, and the defect was easily fixed due to the vulnerability of the control unit that controls free rotation.

본 고안은 종래의 자유회전드라이버에 있어서의 위와같은 결점이 자유회전제어부의 구조에서 나오는 것임을 감안 자유회전부의 구조를 개선하므로서 보다 튼튼하고 보다 값싼 자유회전 드라이버를 제공할 수 있도록 안출된 것으로 이를 첨부도면에 의하여 설명하면 다음과 같다.The present invention has been devised to provide a more robust and cheaper free-rotating driver by improving the structure of the free-rotating unit in view of the above drawbacks of the conventional free-rotating driver. Explained as follows.

몸체(1)의 선단에 파이프(2)를 고정되게 끼우고 파이프(2)의 내부에 자석(3)을 내장하며 파이프(2)의 선단에는 임의의 끝날(4)을 결합시킬 수 있게 하여서 된 통상의 것에 있어서 몸체(1)의 톱니바퀴(5)를 핀(6)으로 고착시켰다.The pipe 2 is fixedly inserted at the tip of the body 1, the magnet 3 is embedded in the pipe 2, and the end of the pipe 2 can be joined to an arbitrary end 4. In a normal thing, the gear 5 of the body 1 was fixed with the pin 6.

톱니바퀴(5)의 톱니(5')는 제1도에 도시된 바와같이 톱니바퀴(5)의 후면측에 방사상의 방향으로 형성시키는 것이 바람직하나 통상의 톱니바퀴와 마찬가지로 톱니바퀴(5)의 외주면에 형성시킬 수도 있을 것이다. 이와같은 몸체(1)의 후단으로 부터 가동구(7)를 끼워 축설하는데 가동구(7)에는 별도의 손잡이(8)를 연결고정하는 것이 편리하다.The gear 5 'of the gear 5 is preferably formed in the radial direction on the rear side of the gear 5, as shown in FIG. 1, but the gear 5 of the gear 5 is It may be formed on the outer circumferential surface. From the rear end of the body (1) by inserting the movable opening (7) to the axis of the movable opening (7) it is convenient to connect and secure a separate handle (8).

가동구(7)와 손잡이(8)가 몸체(1)를 축으로 하여 회동자재로우면서도 외방으로 빠져나가지 아니하도록 하기 위하여 몸체(1)의 후단에 둥근 홈(9)을 형성시키고 손잡이(8)에 보울트(10)를 끼워 보울트(10)의 선단이 홈(9)상에 위치되게하여 손잡이(8)의 회전에 따라 보울트(10)의 선단이 몸체(1)의 홈(9)을 따라 회전이 가능하나 보울트(10)를 풀어내지 않으면 가동구(7)나 손잡이(8)가 외방으로 이탈되지 아니하게 한다.In order to ensure that the movable opening 7 and the handle 8 are rotated about the body 1 and do not escape outward, a round groove 9 is formed at the rear end of the body 1 and the handle 8 Insert the bolt 10 into the groove 10 so that the tip of the bolt 10 is positioned on the groove 9 so that the tip of the bolt 10 rotates along the groove 9 of the body 1 as the handle 8 rotates. This can be done, but if the bolt 10 is not released, the movable port 7 or the handle 8 will not be released outward.

가동구(7)에는 톱니바퀴(5)쪽으로 구멍(11)을 형성시키고 이 구멍(11)에 둥근 선택막대(12)를 스프링 (13)으로 탄설하였다. 선택막대(12)의 선단에는 수직부 (14)와 경사부(14')를 두어 끝모양으로 형성시켰는바 선택막대(12)가 스프링(13)에 의해 외방으로 빠져나가는 것을 방지함과 동시에 선택막대(12)의 회동위치를 선택 할 수 있도록 손잡이(15)를 선택막대(12)의 경사부(14)반대방향인 외면에 끼웠다. 선택막대(12)의 손잡이(15)는 가동구(7)의 절삭부(7')상에 위치시키므로서 선택막대(12)의 회전이 가능하도록 하였다.In the movable opening 7, a hole 11 was formed toward the gear 5, and a round selection bar 12 was installed in the hole 11 with a spring 13. At the tip of the selection rod 12, a vertical portion 14 and an inclined portion 14 'are formed in an end shape. The selection rod 12 is prevented from escaping outwardly by the spring 13 and is simultaneously selected. The knob 15 was fitted to the outer surface opposite to the inclined portion 14 of the selection rod 12 so as to select the rotational position of the rod 12. The knob 15 of the selection rod 12 is positioned on the cutting portion 7 'of the movable opening 7 so that the selection rod 12 can be rotated.

이와같이 구성된 본 고안은 손잡이(8)나 가동구(7)가 몸체(1)에 축설되어 있으므로 손잡이(8)의 회전으로 그 회전력이 몸체(1)에 전달되지 아니한다. 그 회전력은 선택막대(12)와 톱니바퀴(5)의 톱니(5')가 맞물림에 따라 전달될 수 있을 뿐이다.The present invention configured as described above, since the handle 8 or the movable opening 7 is arranged in the body 1, the rotational force is not transmitted to the body 1 by the rotation of the handle 8. The rotational force can only be transmitted as the teeth 5 'of the selection bar 12 and the gear 5 engage.

즉 제3도의 (a)에 도시된 바와같이(이 상태는 제2도의 단면도에 도시된 상태와 동일함) 선택막대(12)의 경사부(14')가 중심방향으로 향하게 되면 선택막대(12)의 선단이 톱니바퀴(5)의 홈(5″)에 끼워지게 되며 그리하면 손잡이(8)를 어느 방향으로 돌리더라도 몸체(1)가 회전된다.That is, as shown in (a) of FIG. 3 (this state is the same as the state shown in the cross-sectional view of FIG. 2), when the inclined portion 14 'of the selection bar 12 is directed toward the center direction, the selection bar 12 ) Is fitted into the groove 5 ″ of the gear 5, and the body 1 is rotated no matter what direction the knob 8 is turned.

그런데 선택막대(12)의 경사부(14')가 제3도의 (b)(c)와 같이 어느 한쪽으로 향하도록 하면 손잡이(8)를 수직부(14)쪽으로 회전시킬때에만 몸체(1)가 동반회전되고 경사부(14')쪽으로 회전시킬때에는 몸체(1)는 동반 회전되지 아니하고 손잡이 (8)만 공회전하여 소기의 목적을 달성할 수 있게 되는 것이다.However, if the inclined portion 14 'of the selection rod 12 faces to one side as shown in (b) and (c) of FIG. 3, the body 1 only when the handle 8 is rotated toward the vertical portion 14 When the rotation is accompanied and rotated toward the inclined portion (14 ') the body (1) is not accompanied by the rotation of the handle (8) is to be able to achieve the intended purpose.

이와같은 본 고안은 손잡이(8)와 몸체(1)를 간단히 선택막대(12)하나로서 임의방향으로 회전되도록 조정할 수 있게 되므로 구조의 단순성으로 인하여 제조가액을 크게 경감시킬 수 있을뿐 아니라 제어부인 자유회전부를 강화할 수 있어 종래와 같은 고장의 염려가 없게되는 효과가 있다.The present invention can be adjusted so that the handle (8) and the body (1) simply rotates in any direction as one selection bar (12) can not only greatly reduce the manufacturing cost due to the simplicity of the structure, but also free control The rotating part can be strengthened, so that there is no fear of failure as in the prior art.
