본 고안은 더블래칫렌치(Double Ratchet Wrench)의 개량에 관한 것으로서, 특히 더블래칫렌치의 손잡이를 조립식으로 연장가능케 하여 볼트나 너트 등을 풀거나 죄이는 작업이 용이하게 이루어질 수 있도록 한 것이다.The present invention relates to an improvement of a double ratchet wrench, and in particular, to allow the handle of the double ratchet wrench to be prefabricated so as to easily loosen or tighten a bolt or nut.

일반적으로 각종 산업용 기계기구 등에서 각종부품을 결합하는 용도로 볼트와 너트가 널리 사용되고 있으며, 상기 볼트와 너트의 분해결합은 멍키나 스패너, 래칫렌치 등 여러 형태의 공구들이 사용되고 있다.In general, bolts and nuts are widely used for joining various components in various industrial machinery and the like, and various types of tools, such as monkeys, spanners, ratchet wrenches, are used for disassembling the bolts and nuts.

특히 더블래칫렌치의 경우에는 머리부에 구성된 조정레버의 조작위치에 따라 볼트나 너트를 풀거나 죄일 수 있는 작업의 편리성 때문에 널리 사용되고 있다.In particular, in the case of a double ratchet wrench, it is widely used because of the convenience of the work that can loosen or tighten the bolt or nut depending on the operation position of the adjustment lever configured in the head.

그러나 종래 사용되고 있는 더블래칫렌치의 경우 손잡이의 길이가 대체로 짧게 구성되어 있다.However, in the case of the conventional double ratchet wrench, the length of the handle is generally short.

따라서 강하게 체결된 볼트와 너트를 풀고 죄이는 작업에는 많은 힘이 요구될 뿐 아니라 특히 분해결합하고자 하는 볼트나 너트가 기계 깊숙히 위치하여 더블래칫렌치의 머리부가 닿지 않을 경우에는 작업하기가 매우 곤란한 등의 단점이 있는 것이었다.Therefore, it is very difficult to loosen and tighten the bolts and nuts that are tightened tightly, and it is very difficult to work especially when the bolt or nut to be disassembled is placed deep inside the machine and the head of the double ratchet wrench does not touch. It was a disadvantage.

본 고안은 이러한 종래의 제반단점을 시정하고자 더블래칫렌치(Double Ratchet Wrench)를 구성함에 있어서, 더블래칫렌치의 손잡이를 필요에 따라 길게 연장될 수 있게 구성하여 강하게 쬐여진 볼트나 너트를 쉽게 풀수 있게 할 뿐 아니라 종래 더블래칫렌치로는 길이가 짧아 작업이 곤란하였던 기게의 내부 깊숙한 곳까지 작업이 가능토록 한 것이다.The present invention is to construct a double ratchet wrench to correct the above-mentioned general disadvantages, the handle of the double ratchet wrench can be configured to be extended as long as necessary to easily loosen the strongly sunk bolts and nuts In addition to the conventional double ratchet wrench is short to the length of the interior of the machine was difficult to work was to be able to work.

상기 목적을 달성하기 위하여 본 발명은 더블래칫렌치를 구성함에 있어서, 손잡이 하단에 연결봉체를 일체로 구성하고, 상기 연결봉체상에 보조손잡이를 결합하여 필요에 따라 더블래칫렌치의 손잡이 길이를 보조손잡이 길이만큼 길게 연장하여 사용할 수 있도록 한 것이다.In order to achieve the above object in the present invention, when constructing a double ratchet wrench, the connecting rod body is integrally formed at the lower end of the handle, and the handle length of the double ratchet wrench is combined as necessary to the auxiliary handle length on the connecting rod body. It will be extended to use as long.

이하 본 고안의 실시예를 첨부도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 고안에서 제공하고자 하는 더블래칫렌치(Double Ratchet Wrench)의 사시도이고, 도2는 분해사시도로서, 홀더(21)와 조정레버(22)가 형성된 머리부(20)와 손잡이(30)로 구성된 통상의 더블래칫렌치(10)를 구성하되, 상기 더블래칫렌치(10)의 손잡이(30) 하단에 연결봉체(40)를 구성하고, 연결봉체(40)와 손잡이(30)사이에는 플렌지(41)를 돌출구성하여 연결봉체(40) 일측에 단턱(42)이 구성되게 한다.1 is a perspective view of a double ratchet wrench (Double Ratchet Wrench) to be provided in the present invention, Figure 2 is an exploded perspective view, the head portion 20 and the handle 30, the holder 21 and the adjustment lever 22 is formed Consisting of a conventional double ratchet wrench 10, but comprises a connecting rod 40 in the lower end of the handle 30 of the double ratchet wrench 10, between the connecting rod 40 and the handle 30 flange Protruding portion (41) so that the stepped 42 is configured on one side of the connecting rod (40).

상기 연결봉체(40)에 보조손잡이(50)를 결합하여 더블래칫렌치(10)의 손잡이(30)가 보조손잡이(50) 만큼 길게 구성하여서 된 것이다.The handle 30 of the double ratchet wrench 10 is configured to be as long as the auxiliary handle 50 by coupling the auxiliary handle 50 to the connecting rod 40.

이때 손잡이(30) 하단에 구성된 연결봉체(40)와 보조손잡이(50)를 결합하기 위한 수단은 다음과 같다.At this time, the means for coupling the connecting rod 40 and the auxiliary handle 50 is configured at the bottom of the handle 30 is as follows.

도5에서와 같이 손잡이(30)하단에 구성된 연결봉체(40)상에 요입홈(43)을 뚫어 구성하고 상기 요입홈(43)에 스프링(44)과 탄지볼(45)을 차례로 끼운 다음 요입홈(43) 입구부를 프레스펀칭하여 걸림턱(46)이 형성되게 하므로서 탄지볼(45)이 요입홈(43)에 끼워진 상태에서 일부만 연결봉체(40) 외면으로 돌출되게 구성한다.As shown in FIG. 5, the concave groove 43 is formed on the connecting rod 40 formed at the bottom of the handle 30, and then the spring 44 and the tangy ball 45 are sequentially inserted into the concave groove 43. By press punching the mouth of the mouth groove 43 so that the locking jaw 46 is formed, only a part of the finger ball 45 is inserted into the recess groove 43 so as to protrude outward from the connection rod 40.

동시에 보조손잡이(50)는 내면에 중공부(52)를 형성하고, 상단 일측에 관통공(51)을 뚫어 구성하되, 상기 관통공(51)의 위치는 보조손잡이(50)를 연결봉체(40) 외면에 끼워 보조손잡이(50)의 상단부(53)가 플렌지(41)의 단턱(42)에 접하였을 때 탄지볼(45)이 접하는 위치에 뚫려지게 한다.At the same time, the auxiliary handle 50 is formed by forming a hollow portion 52 on the inner surface, and through the through hole 51 on one side of the upper end, the position of the through hole 51, the auxiliary handle 50 is connected to the rod body 40 When the upper end 53 of the auxiliary handle 50 is in contact with the step 42 of the flange 41 is inserted into the outer surface so that the tangy ball 45 is in contact with the outer surface.

따라서 보조손잡이(50)의 중공부(52)가 손잡이(30)하단에 구성된 연결봉체(40) 외면에 끼워지게 하면 보조손잡이(50)의 상단부(53)가 플렌지(41)의 단턱(42)에 접하면서 더 이상 끼워지지 않고, 상기한 상태에서 보조손잡이(50)를 천천히 회전시키면 탄지볼(45)와 관통공(51)이 일치하게 되고, 동시에 탄지볼(45)이 스프링(44)의 탄지력에 의해 관통공(51)내에 조립되므로 보조손잡이(50)의 조립이 완료된다.Therefore, when the hollow portion 52 of the auxiliary handle 50 is fitted to the outer surface of the connecting rod 40 formed at the bottom of the handle 30, the upper end 53 of the auxiliary handle 50 is stepped 42 of the flange 41. If the auxiliary knob 50 is slowly rotated in the above state while being in contact with each other, the tangy ball 45 and the through hole 51 coincide with each other, and at the same time, the tangy ball 45 of the spring 44 Since the assembling is assembled into the through hole 51 by the holding force, the assembly of the auxiliary handle 50 is completed.

상기에서와 같이 연결봉체(40)외면에 보조손잡이(50)가 결합된 상태에서 분리시키고자 할 경우에는 보조손잡이(50)를 외측방향으로 잡아당기면 연결봉체(40)로부터 보조손잡이(50)가 간단히 분리된다.When the auxiliary handle 50 is to be separated in the state in which the auxiliary handle 50 is coupled to the outer surface of the connecting rod 40 as described above, the auxiliary handle 50 is pulled from the connecting rod 40 by pulling the auxiliary handle 50 outward. Simply separated.

연결봉체(40)에 보조손잡이(50)를 결합하기 위한 또 다른 수단은 도6에서와 같이 연결봉체(40)에 외면나사부(47)를 구성하고, 보조손잡이(50)의 내면 중공부(52)에 내면나사부(55)를 구성하여 상기 내외면 나사부(47)(55)가 조립되게 하므로서 손잡이(30)단부에 보조손잡이(50)가 조립되게 할 수도 있다.Another means for coupling the auxiliary handle 50 to the connecting rod 40 constitutes the outer thread portion 47 to the connecting rod 40 as shown in Figure 6, the inner hollow portion 52 of the auxiliary handle 50 By configuring the inner screw portion 55 to the inner and outer surface screw portion 47, 55 may be assembled to the auxiliary handle 50 to the end of the handle (30).

이와 같이 구성된 본 고안의 더블래칫렌치(10)는 평소에는 손잡이(30)를 잡고 머리부(20)에 구성된 홀더(21)를 이용하여 볼트나 너트를 분해조립하는 용도로 사용한다는 것은 동일하다. The double ratchet wrench 10 of the present invention configured as described above is usually used for the purpose of disassembling and assembling bolts and nuts using the holder 21 configured at the head 20 by holding the handle 30.

그러나 본 고안에서 제공하고자 하는 더블래칫렌치(10)는 강하게 결합된 볼트나 너트를 풀어내거나 조립할 때, 혹은 작업하고자 하는 볼트나 너트가 기계 깊은 곳에 장치되어 있어 손잡이(30)만으로는 머리부(20)의 홀더(21)가 닿지 않을 때 편리하게 사용할 수 있게 된다.However, the double ratchet wrench 10 to be provided in the present invention is when the bolt or nut is loosely assembled or assembled, or the bolt or nut to be worked is installed in a deep machine so that the handle 30 alone is the head 20. When the holder 21 is not in contact can be used conveniently.

즉, 더블래칫렌지(10)를 구성하는 손잡이(30)하단 연결봉체(40) 외면에 보조손잡이(50)를 결합하면 손잡이(30)로부터 보조손잡이(50) 만큼 길이를 연장시킬 수 있게 되므로 볼트나 너트를 풀고 죄일 때 작은 힘으로도 쉽게 작업할 수 있게 되고, 또한 보조손잡이(50) 길이만큼 작업범위를 넓힐 수 있게 된다.That is, when the auxiliary handle 50 is coupled to the outer surface of the connecting rod 40 at the bottom of the handle 30 constituting the double ratchet 10, the length of the auxiliary handle 50 can be extended from the handle 30 to the bolt. When loosening and tightening the nut, it is possible to easily work with a small force, and also to extend the working range by the length of the auxiliary handle (50).

본 고안에 있어서 보조손잡이(50)의 결합수단으로서 연결봉체(40)에 탄력설치된 탄지볼(45)이 보조손잡이(50)의 관통공(51)에 끼워져 결합되게 하는 수단은 보조손잡이(50)의 조립 및 분리가 신속용이하게 이루어지게 되는 장점이 있다.In the present invention, as a coupling means of the auxiliary handle 50, the means for allowing the ball 50 to be elastically installed in the connecting rod 40 to be inserted into the through hole 51 of the auxiliary handle 50 is coupled to the auxiliary handle 50. There is an advantage that the assembly and separation of the made easy.

또한 연결봉체(40)에 구성된 외면나사부(47)가 보조손잡이(50)에 구성된 내면나사부(55)에 조립되게 하는 수단은 연결봉체(40) 외면에 보조손잡이(50)를 견고하게 조립할 수 있는 장점이 있다.In addition, the means for allowing the outer thread portion 47 formed on the connecting rod 40 to be assembled to the inner threaded portion 55 formed on the auxiliary handle 50 can be firmly assembled to the auxiliary handle 50 on the outer surface of the connecting rod 40. There is an advantage.

이상 설명한 바와 같이 본 고안은 더블래칫렌치를 구성함에 있어서, 손잡이 하단에 연결봉체를 구성하고, 상기 연결봉체 외면에 보조손잡이를 착탈가능케 구성하여 필요에 따라 손잡이를 길게 연장하여 사용케 하므로서 작업환경이나 여건에 따라 편리하게 사용할 수 있게 되는 등의 효과가 있는 것이다.As described above, in the present invention, when constructing a double ratchet wrench, a connecting rod is formed at the bottom of the handle, and an auxiliary handle is detachably configured on the outer surface of the connecting rod so that the handle can be extended to be used as necessary to extend the working environment or Depending on the circumstances, such effects can be used conveniently.
