상기와 같이 구성된 본 발명의 조립순서와 작용에 대해 설명한다.The assembly sequence and operation of the present invention configured as described above will be described.

상기 고무부재(243)를 벌려서 제2연장부재(242)의 플랜지(242a)를 타고넘어 캠축부(242b)에 끼운상태로 고무부재(243)의 돌기(243b)가 캠축부(242b)의 평면(c)에 안착되게 한다.The protrusion 243b of the rubber member 243 is flat on the camshaft 242b in a state where the rubber member 243 is opened to cross the flange 242a of the second extension member 242 and fitted into the camshaft 242b. settles in (c).

이후 상기 고무부재(243)의 돌기(243b)를 상기 제1연장부재(241)의 파이프끼움부(241b)에 형성된 고무부재고정슬롯(241c)에 밀어넣어 안착시킨다.Thereafter, the protrusion 243b of the rubber member 243 is pushed into the rubber member fixing slot 241c formed in the pipe fitting portion 241b of the first extension member 241 to be seated.

다음 상기 고정파이프부재(244)를 상기 제2연장부재(242)의 고정부(242c)로 통과시켜 상기 파이프끼움부(241b)에 끼운 다음, 상기 흡입장치(100)의 연결관부(120)에 구비된 상기 출몰돌기(110)가 출몰돌기착탈구멍(241a)에 안착되도록 제1연장부재(242)를 결합한다.Next, the fixing pipe member 244 is passed through the fixing part 242c of the second extension member 242 to be inserted into the pipe fitting part 241b, and then to the connection pipe part 120 of the suction device 100. The first extension member 242 is coupled so that the provided projection protrusion 110 is seated in the projection projection detachment hole 241a.

또한 상기 손잡이조작부(220)에 제2연장부재(242)의 고정부(242c)를 끼워서 고정하게 된다.In addition, the fixing part 242c of the second extension member 242 is fixed to the handle manipulation part 220.

이때 상기 제2연장부재(242)의 평면(c)은 제1연장부재(241)의 길이조절부(241e)의 위상각과 동일하게 상기 고정파이프부재(244)를 상기 파이프끼움부(241b)에서 뒤쪽으로 빼낸 경우에는 길이방향으로의 조작이 자유롭게 된다.At this time, the plane c of the second extension member 242 is the same as the phase angle of the length adjusting part 241e of the first extension member 241 to the fixed pipe member 244 in the pipe fitting portion 241b. When pulled out backward, the operation in the longitudinal direction is free.

이후 상기 고정파이프부재(244)를 파이프끼움부(241b)에 끼우게 되면 제4도 및 제5도에 도시된 것과 같은 상태가 된다.Then, when the fixed pipe member 244 is inserted into the pipe fitting portion 241b, the state as shown in FIGS. 4 and 5 is obtained.

또한 제6도 및 제7도에 도시된 것과 같이, 상기 제1연장부재(241)에서 제2연장부재(242)를 최대한 뽑은 상태에서 상기 제2연장부재(242)의 평면(c)이 길이조절부(241e)의 위상각과 어긋나도록 회전시키게 되면 상기 제2연장부재(242)가 길이방향으로 이동되지 않게 된다.In addition, as shown in FIGS. 6 and 7, the plane c of the second extension member 242 is long in the state in which the second extension member 242 is pulled out from the first extension member 241 as much as possible. When rotated so as to deviate from the phase angle of the adjusting unit 241e, the second extension member 242 is not moved in the longitudinal direction.

즉, 상기 제2연장부재(242)의 평면이 길이조절부(241e)의 위상각과 어긋나도록 회전시키게 되면, 상기 고정파이프부재(244)에 의해 돌기(a)가 가압되어 길이조절부(241e)가 하강하게 되므로 상기 제2연장부재(242)의 플랜지(242a)가 길이조절부(241e)에 걸려서 길이조절이 이루어지지 않게 된다.That is, when the plane of the second extension member 242 is rotated so as to deviate from the phase angle of the length adjusting part 241e, the projection a is pressed by the fixed pipe member 244, thereby adjusting the length adjusting part 241e. Since it is lowered, the flange 242a of the second extension member 242 is caught in the length adjusting portion 241e so that the length is not adjusted.

또한 상기 고정파이프부재(244)를 파이프끼움부(241b)에 끼운상태로 제2연장부재(242)를 90도 가량회전시키게 되면, 상기 고무부재(243)의 돌기(243b)가 제2연장부재(242)의 캠축부(242b)에 의해 가압되어, 축방향으로의 이동이 추가적으로 제한된다.In addition, when the second extension member 242 is rotated about 90 degrees while the fixing pipe member 244 is inserted into the pipe fitting portion 241b, the protrusion 243b of the rubber member 243 is the second extension member. Pressed by the camshaft portion 242b of 242, the movement in the axial direction is further restricted.

그리고 상기 플랜지(242a)는 상기 고무부재(243)의 뒤쪽면에 밀착되게 되어 상기 제1연장부재(241)에서 제2연장부재(242)가 신축될 때 상기 고무부재(243)와 제2연장부재(242)의 사이로 공기가 누출되는 것을 방지하게 된다.And the flange 242a is in close contact with the rear surface of the rubber member 243 when the second extension member 242 in the first extension member 241 is stretched and the rubber member 243 and the second extension This prevents air from leaking between the members 242.

이상 설명한 바와 같이 본 발명에 의하면, 흡입장치와 연통장치를 구성하는 손잡이조절부의 사이에 설치된 연장관조립체가 신축가능하도록 설치되어, 사용하기에 편리함은 물론, 부품의 분실염려가 없는 효과가 있다.As described above, according to the present invention, the extension tube assembly provided between the suction device and the handle adjusting part constituting the communication device is installed to be stretchable, so that it is convenient to use and there is no effect of losing the parts.

이상에서 본 발명의 구체적인 일 실시예를 상세히 설명하였으나, 본 발명은 이에 한정되는 것은 아니며, 이 분야의 통상의 지식을 가진 자라면 본 발명의 기술적 사상을 바탕으로 다양한 변경과 수정이 가능할 것이다.Although one specific embodiment of the present invention has been described in detail above, the present invention is not limited thereto, and various changes and modifications may be made by those skilled in the art based on the technical idea of the present invention.
