본 고안은 휴대용 천공기의 드릴방향전환장치에 관한 것으로 천공기를 선단부와 후단부로 구분하여 보울트로 결합하되, 보울트의 조임에 또는 해지에 의한 선단부의 절곡으로 드릴의 방향을 90°회동자재케 함과 동시에 모우터에 의하여 회전하는 회동축상에 대향하는 베벨기어를 구성하여 선단부의 절곡시 대향하는 양베벨기어가 치합토록 함으로서 용도에 따라 전방 또는 좌향 및 우향으로 작업가능케 함을 목적으로 한 것이다.The present invention relates to a drill direction switching device of a portable drilling machine, which is divided into a front end and a rear end and combined with a bowl, and the direction of the drill is rotated 90 ° by tightening the bolt or by bending the end part by disengaging. It is an object of the present invention to construct a bevel gear that faces the rotating shaft rotated by a motor so that the opposite bevel gears engage when the tip portion is bent, so that the work can be performed forward or leftward and rightward depending on the purpose.

즉, 종래의 천공기는 전체가 단일체로 구성되어 작업의 용도가 전방으로 국한됨으로서 작업환경에 따른 협소한 공간부상에서 좌 또는 우측으로의 천공작업이 여의치 못하며, 작업능률이 저하되는등 그 작업 반경이 극히 제한적인 문제점이 대두 되었다.That is, the conventional boring machine is composed of a single whole body, and the use of the work is limited to the front, so that the drilling work to the left or right in a narrow space portion according to the working environment is not feasible, and the working radius is deteriorated. Extremely limited problems have arisen.

본 고안은 상기와 같은 제반 문제점을 해소하고자 한 것으로 이하 본 고안을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is intended to solve the above problems as described below in detail with reference to the accompanying drawings of the present invention.

드릴(8) 및 손잡이(9)가 구성된 통상의 휴대용 천공기(A)에 있어서, 상기 천공기(A)를 선단부(1)와 후단부(2)로 구분하되, 그 양측면에는 보울트(3), (3')로 결합하고 전, 후방으로 구분된 회전축봉(4), (4')의 일단에는 베벨기어(5), (5')를 상호 대향되게 구성하여 그 전면에는 ㄷ형 삽지구(6) 및 이에 끼워지는 삽입각체(7)를 각각 구성하여된 것으로, 미설명부호(10)은 상부보호캡, (11), (11')는 측면보호 주름판, (12)는 척, (13)은 모우터, (14)는 스위치를 보인 것이다.In a conventional portable drilling machine (A) consisting of a drill (8) and a handle (9), the drilling machine (A) is divided into a front end portion (1) and a rear end portion (2), and bolts (3), ( 3 ') and bevel gears (5) and (5') are opposed to each other at one end of the rotating shaft (4) and (4 ') divided into front and rear, and the front of the c-shaped insert (6) And it is configured to be inserted into the insert body (7), the reference numeral 10 is the upper protective cap, (11), (11 ') is a side protective corrugated plate, (12) the chuck, (13) Silver motor, 14 showing a switch.

이와 같이 구성된 본 고안의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.

즉, 통상적인 전방으로의 작업을 행하고자 할 때에는 선단부(1) 및 후단부(2)를 직선상의 길이방향으로 유지시켜 보울트(3), (3')로 견고히 조여 고정하게 되면 그 내측의 전방회전축봉(4)의 일단에 형성된 ㄷ형 삽지구(6)내에 일측 후방회전축봉(4')의 삽입각체(7)가 끼워진 상태로 연동되며, 스위치(14)의 작동과 드릴(8)이 작업면에 접면됨과 동시에 전원이 접점되어 모우터(13)가 가동, 후방회동축봉(4') 및 이와 연동된 전방회동축봉(4)과 드릴(8)이 회전하게 되며, 이때 대응된 양 베벨기어(5), (5')는 공회전만 하게 된다.That is, in order to perform a normal forward work, if the front end 1 and the rear end 2 are held in a straight longitudinal direction and firmly tightened and fixed by bolts 3 and 3 ', the front of the inner side thereof is fixed. In the c-shaped insertion slot 6 formed at one end of the rotary shaft 4, the insertion body 7 of the one side of the rear rotary shaft 4 'is interlocked, and the operation of the switch 14 and the drill 8 work. In contact with the surface and at the same time the power is contacted, the motor 13 is moved, the rear pivot shaft 4 'and the front pivot shaft 4 and the drill (8) interlocked with it rotates, the corresponding amount Bevel gears 5 and 5 'only idle.

한편 협소한 공간부내에서의 측면 작업을 행하고자 할 때에는, 양 보울트(3), (3')를 나해하여 선단부(1)를 직하방으로 굴절시키게 되면, 측면의 보호주름판(11), (11')은 선단부(1)의 굴절과 동시에 그 상부는 신장되고 저부는 수축되어 호형을 이루면서 선단부(1)의 방향전환이 가능한 것이며, 따라서 절곡되는 선단부(1)가 보울트(3), (3')를 축지점으로하여 회동하여 완전 90°로 절곡된 상태에서 보울트(3), (3')로 다시조여 고정시키게 된다.On the other hand, when the side work is to be performed in the narrow space part, when both ends (3) and (3 ') are deflected and the front end part 1 is bent downward, the protective pleats 11, ( 11 ') is the refraction of the tip portion (1) at the same time the upper portion is extended and the bottom portion is contracted to form an arc, the direction of the tip portion (1) is possible, so that the bent tip portion (1) is the bolt (3), (3 Rotating with ') as the shaft point, it is fixed by tightening again with bolts (3) and (3') in a state of being bent at 90 °.

이때, 그 내측의 전방회전축봉(4)도 직하방으로 위치가 이동되면서 전방회전축봉(4) 일단의 ㄷ형 삽지구(6)는 후방회전축봉(4')의 삽입각체(7)에서 벗어나게 되고 동시에 양 베벨기어(5), (5')는 치합되므로서 모우터(13)에 의한 후방회전축봉(4')의 회전에 의하여 전방회동축봉(4)도 그 방향이 이동된 상태에서 회동가능하여 이와 연동된 드릴(8)도 회전하게 된다.At this time, the front rotary shaft bar 4 of the inner side is also moved directly downward, while the c-shaped insertion slot 6 of the front rotary shaft bar 4 is out of the insert body 7 of the rear rotary shaft bar 4 '. At the same time, both bevel gears 5 and 5 'are engaged, and the front pivot shaft 4 is also rotated by the rotation of the rear pivot shaft 4' by the motor 13 while the direction thereof is moved. It is possible to rotate the drill (8) associated with it.

이와같이 본 고안은 보울트(3), (3')의 나해 또는 조임에 의하여 천공기의 선단부(1)를 간단히 절곡 또는 고정할 수 있고, 상부 보호캡(10) 및 측면 보호주름판(11), (11')은 작업시 이물질의 진입을 방지하게 되어 이물질에 의한 기기의 고장을 미연에 방지할 수 있는 효과가 있다.In this way, the present invention can be easily bent or fixed to the tip portion 1 of the perforator by screwing or tightening the bolts 3 and 3 ', and the upper protective cap 10 and the side protective pleats 11, ( 11 ') prevents the entry of foreign materials during the work, which can prevent the failure of the equipment caused by the foreign materials.
