본 고안은 감속기(1단감속~다단, 내치차를 이용한 유성기어 감속기 등)의 회전 토르크 증가를 이용하여 힘들이지 않고 용이하게 넛트를 회전시킬수 있도록한 렌치에 관한것이다.The present invention relates to a wrench that allows the nut to be easily and easily rotated using an increase in the torque of the reduction of the reduction gear (single gear reduction to multiple gears, a planetary gear reducer using an internal gear).

종래의 렌치는 넛트를 단순히 사람의 힘에 의하여 조이거나 풀어내었기 때문에 많은 힘이 들었고, 더욱 기계들(공기압 또는 유압기기들)에 의해 죄여졌던 넛트를 사람의 힘만으로 풀어낼 경우에는 여간 어려운 일이 아니었다. 본 고안은 이와같은 불편을 해결하기 위하여 창안된 것으로 첨부 도면에 의하여 그 실시예를 상세히 설명하면 다음과 같다.Conventional wrenches require a lot of force because the nut is simply tightened or released by human force, and it is sometimes difficult to release the nut, which has been tightened by machines (pneumatic or hydraulic equipment), by human force alone. This was not. The present invention was devised to solve such inconveniences, and the embodiments will be described in detail with reference to the accompanying drawings.

도면에 표시된 실시예는 2단 감속 장치를 사용한 것으로 먼저 소켓(3)을 풀려고 하는(혹은 잠구려고 하는) 넛트에 끼우고 손잡이(2)를 돌리면 기어(5)가 돌아서, 맞물려 있는 기어(7)가 돌고, 같은 축상의 기어(8)도 돌게되고 기어(8)과 물려있는 기어(6)이 돌게되면 축(10)일단에 장치되어 있는 소켓 렌치(3)의 회전에 의하여 넛트를 풀어 내거나 혹은 잠글수 있다. 본 도면에는 2단 감속을 도시한 것이나 1단 감속 혹은 필요에 따라 다단 또는 내치차를 이용하여 전체 부피를 최소로 적게 할수도 있다.The embodiment shown in the drawing uses a two-stage reduction gear, first of which is inserted into a nut which is intended to loosen (or lock) the socket 3 and when the knob 2 is turned, the gear 5 is turned, thereby engaging the gear 7 ), The gear 8 on the same shaft is turned, and the gear 8 and the gear 6 are rotated to release the nut by the rotation of the socket wrench 3 installed at the end of the shaft 10, or Or lock it. This figure shows the two-stage deceleration, but may reduce the total volume to a minimum by using the first-stage deceleration or multistage or internal gearing as necessary.

핸들(2)의 회전력은 감속비의 반비례로 증가한 출력축(10)의 회전 토르크를 얻어낼수 있으므로 적은 힘으로 넛트를 풀어내거나 잠글수 있는것이다.Since the rotational force of the handle 2 can obtain the rotation torque of the output shaft 10 which is increased in inverse proportion to the reduction ratio, the nut can be released or locked with little force.

본 고안의 다른 실시예로써 자동차가 주행중 펑크로 바퀴를 교환할시에 더욱 대형 차량일 경우 바퀴의 고정 넛트를 풀어낸다는 것은 대단히 힘드는 작업이다. 소켓 렌치에 긴 바를 끼우고 또 파이프를 끼워서 잡아다녀도 좀처럼 풀려지지 않는다. 그러한 경우 본 고안품은 대단히 편리하고 손쉽게 작업할수 있도록한 것이다. 핸들(2)대신에 일방향 레쳇 핸들(9)를 사용할수도 있으며, 미설명부호(4)는 본고안품의 자체(1)가 역회전하는것을 방지하기 위해 설치한 지지봉임.As another embodiment of the present invention, when the vehicle is a larger vehicle when the wheel is replaced with a punk while driving, it is a very difficult task to release the fixing nut of the wheel. A long bar on a socket wrench and a pipe can easily be pulled out. In this case, the present invention is very convenient and easy to work. The one-way level handle (9) may be used instead of the handle (2). Unexplained reference numeral (4) is a supporting rod installed to prevent reverse rotation of the product itself (1).
