본 고안은 볼트 헤드와 너트(이하 편의상 볼트로 통일하여 지칭한다)의 크기에 관계없이 사용할 수 있으며, 볼틀를 일측 방향으로만 회전시킬 수 있게한 래칫기어(ratchet gear)가 형성된 렌치에 관한 것이다.The present invention can be used regardless of the size of the bolt head and nut (hereinafter referred to collectively as a bolt), and relates to a wrench having a ratchet gear (rotchet gear) is formed to allow the ball frame to rotate in only one direction.

통상 볼트와 너트를 편리하게 풀거나 조이기 위한 공구로서는 렌치와 래칫기어(reachet gear)가 형성된 스패너가 사용되는바, 종래의 렌치는 하나의 기구로서 다양한 규격의 볼트를 체결할 수 있는 공구 절약의 편의성이 있는 반면 볼트의 체결 작업 과정에서는 렌치의 정.역회전시마다 렌치를 볼트에 끼우고 빼는 작업을 반복해야하는 불편이 있고, 종래의 래칫기어가 형성된 스패너는 볼트의 체결작업 과정에서 렌치의 정.역 회전시에 렌치를 볼트에 끼우고 빼는 과정없이 연속하여 볼트를 풀고 조이는 작성상의 편리성이 있는 반면 여러가지 규격의 복스를 별도로 구비하여야 하는 불편이 있었다.Generally, a wrench for forming a wrench and a ratchet gear is used as a tool for easily loosening or tightening a bolt and a nut. The conventional wrench is a tool that can be used to fasten bolts of various sizes. On the other hand, in the process of tightening the bolt, it is inconvenient to repeat the operation of inserting and removing the wrench into the bolt every time the forward and reverse rotations of the wrench. While rotating, there is a inconvenience in that the bolts of various specifications must be separately provided while there is convenience in writing and unfastening the bolt continuously without the process of inserting and removing the wrench into the bolt.

본 고안은 상기와 같은 종래의 문제점을 착안하여 렌치의 이동조오(jaur)에 래칫기어를 형성하여 하나의 렌치로서 다양한 규격의 볼트를 체결할 수 있도록 함과 동시에 렌치가 역회전(공회전)하는 과정에서는 볼트가 고정되어 있고 정회전시만다 회전되게 하여 렌치의 연속반복적인 정역회전 작용하에서도 볼트를 일측 방향으로만 구동될수 있게 함으로써 렌치가 래칫기어 스패너의 역할을 겸하도록한 것으로 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is to focus on the conventional problem as described above to form a ratchet gear in the jaw of the wrench to fasten the bolts of various specifications as a wrench and at the same time the wrench reverse rotation (idling) In this example, the bolt is fixed and rotates only in the forward direction so that the bolt can be driven only in one direction even under the continuous and reverse rotation of the wrench so that the wrench also functions as a ratchet gear spanner. It will be described in detail as follows.

손잡이(2)가 형성된 고정간(3)의 선단에 2개의 고정돌기(4)를 형성하고 상기 고정간(3)의 고정돌기(4) 내측에 통공(10)을 뚫은 후 L자형 이동조오(5)의 고정부(5a)하단에 3개의 요입홈(6)을 형성하고,형 고정조오(7)의 하측내부를 개방하여 한쌍의 고정간(7a) (7b)을 형성한 다음 각 고정간(7a) (7b)일측에 통공(11)을 뚫는다.After forming the two fixing protrusions 4 at the tip of the fixing bar (3) formed with the handle (2) and the through hole (10) inside the fixing protrusion (4) of the fixing bar (3) L-shaped moving jaw ( 5, three recessed grooves 6 are formed at the bottom of the fixing part 5a. The lower inner portion of the mold fixing jaw 7 is opened to form a pair of fixing rods 7a and 7b, and then a hole 11 is drilled on one side of each fixing rod 7a and 7b.

이상과 같이된 상태에서 코일스프링(9)의 외측 선단을 고정조오(7)의 고정간(7a) (7b)일측에 고정시키고, 코일스프링(9)의 내측 선단은 고정간(3)의 통공(10)측면에 고정시킨후 이동조오(5)의 고정부(5a)를 고정조오(7)의 고정간(7a) (7b)사이에 끼우고, 고정간(3)의 고정돌기(4)를 고정간(7a) (7b)하측에서 끼운다음 고정간(3)의 고정돌기(4)가 고정간(7a) (7b)내에서 이동조오(5)의 요입홈(6)에 접지되게 한 다음 핀축(8)이 고정간(7a) (7b)의 통공(11)과 고정간(3)의 통공(10) 및 코일스프링(9)을 관통하게하여 고정조오(7)를 고정간(3)에 축설 시킨다.In the above state, the outer end of the coil spring 9 is fixed to one side of the fixing jaws 7a and 7b of the fixing jaw 7, and the inner end of the coil spring 9 has a through hole in the fixing section 3. (10) After fixing to the side, the fixing part 5a of the moving jaw 5 is sandwiched between the fixing bars 7a and 7b of the fixing jaw 7, and the fixing projection 4 of the fixing bar 3 is fixed. The lower end of the fixed bar (7a) (7b), and then the fixing projection (4) of the fixed bar (3) is grounded in the recessed groove (6) of the movable jaw (5) in the fixed bar (7a) (7b). Next, the pin shaft 8 passes through the through hole 11 of the fixed section 7a and 7b and the through hole 10 and the coil spring 9 of the fixed section 3 so that the fixed jaw 7 is fixed to the fixed section 3. )

이상과 같은 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention as described above are as follows.

본 고안에 의한 렌치를 볼트를 체결할 때에 렌치(1)의 이동조오(5)를 고정조오(7)로부터 벌려서 이동조오(5)와 고정조오(7)사이에 볼트를 끼운다음 렌치(1)를 회전시켜 볼트를 체결하는 것으로서 고정조오(7)를 손으로 잡은후 핀축(8)을 축으로하여 손잡이(2)를 고정조오(7)방향으로 회전시키면 고정간(3)의 고정돌기(4)가 이동조오(5)의 고정부(5a)를 밀어내어 이동조오(5)가 고정조오(7)로부터 벌어진다.When tightening the bolt of the wrench according to the present invention, open the movable jaw (5) of the wrench (1) from the fixed jaw (7) and insert the bolt between the movable jaw (5) and the fixed jaw (7), and then the wrench (1) After holding the fixing jaw (7) by hand to rotate the bolt to rotate the handle (2) in the direction of the fixing jaw (7) with the pin shaft (8) as a shaft to fix the fixing projection (4) ) Pushes the fixed part 5a of the movable jaw 5, and the movable jaw 5 opens from the fixed jaw 7.

이상태에서 볼트를 회전시키고자 하는 방향에 이동조오(5)가 오도록하여 이동조오(5)와 고정조오(7)사이를 볼트에 밀어놓고 고정조오(7)에서 손을 떼면 스프링의 탄지력에 의하여 고정조오(7)가 회전되면서 고정조오(7)의 이동조오(5)사이가 좁혀져서 고정조오(7)와 이동조오(5)사이에 볼트가 끼워진다.In this state, move the moving jaw (5) in the direction to rotate the bolt, push the moving jaw (5) and the fixed jaw (7) between the bolts and remove the hand from the fixed jaw (7) by the spring force As the fixed jaw 7 is rotated, the movable jaw 5 of the fixed jaw 7 is narrowed so that a bolt is inserted between the fixed jaw 7 and the movable jaw 5.

이상과 같이된 상태에서 손잡이(2)를 정역방향으로 연속 반복되게 회전시키면 손잡이(2)가 볼트를 회전시키고자 하는 방향(이동조오방향)으로 회전할때는 손잡이(2)의 고정돌기(4)에 전해진 회전력이 이동조오(5)의 요입홈(6)으로 전달되고 요입홈(6)에 전달된 회전력은 이동조오(5)에 전달되어 볼트를 회전시키게 되나(제2a도) 손잡이(2)가 볼트를 회전시키고자 하는 방향의 반대방향(고정조오방향)으로 회전할때 즉 렌치의 공회전시에는 손잡이(2)의 고정돌기(4)에 전해진 회전력이 이동조오(5)의 요입홈(6)으로 전달되어 이동조오(5)를 고정조오(7)의 반대방향으로 밀어냄으로써 고정조오(7)와 이동조오(5)사이가 벌어져 볼트의 회전없이 렌치만이 공회전하게 되는 것이다. (제2b도)In the above state, if the handle 2 is continuously rotated in the forward and reverse directions, the handle 2 rotates in the direction to move the bolt (moving jaw direction) to the fixing projection 4 of the handle 2. The transmitted rotational force is transmitted to the concave groove 6 of the moving jaw 5 and the rotational force transmitted to the concave groove 6 is transmitted to the moving jaw 5 to rotate the bolt (FIG. 2a). When the bolt is rotated in the opposite direction to the direction to be rotated (fixed jaw direction), that is, when the wrench is idle, the rotational force transmitted to the fixing protrusion 4 of the handle 2 is recessed in the recess 6 of the movable jaw 5. It is transmitted to the pushing jaw (5) in the opposite direction of the fixed jaw (7) by the gap between the fixed jaw (7) and the moving jaw (5) is to be idle only the wrench without the rotation of the bolt. (Figure 2b)

이상과 같이 본 고안은 고정조오(7)를 고정간(3)에 결합시키고 고정조오(7)의 고정간(7a) (7b)사이에 삽지된 이동조오(5)의 요입홈(6)내에 고정간(3)의 고정돌기(4)를 결합시키는 간단한 방법에 의하여 다양한 규격의 볼트를 체결 및 해리 할수 있을뿐만 아니라 렌치의 연속 반복적인 정역회전에서도 볼트를 원하는 일측방향으로만 회전시켜서 체결 및 해리할 수 있는 매우 실용적인 고안이다.As described above, the present invention couples the fixed jaw 7 to the fixed bar 3 and in the recess 6 of the movable jaw 5 inserted between the fixed bar 7a and 7b of the fixed jaw 7. Not only can the bolts of various sizes be fastened and dissociated by a simple method of engaging the fixing protrusions 4 of the fixed section 3, but also the bolts are rotated only one direction in the desired direction even in the continuous repeated reverse rotation of the wrench. It is a very practical design.
