Description
본 고안은 주로 금속을 자르는 쇠톱대에 관한 것으로 보다 상세하게는 상기 쇠톱대에 소정의 긴장수단을 구비시켜 톱날을 장착하기 전 쉽게 톱날이 이탈되는 것을 방지하므로서 톱날 교체 및 장착이 용이하게 한 것이다.The present invention mainly relates to a hacksaw for cutting metal, and more particularly, it is provided with a predetermined tension means in the hacksaw to prevent the saw blade from detaching easily before mounting the saw blade, thereby making it easy to replace and install the saw blade.
통상적으로 쇠톱대는 도 1과 같이 일측은 톱날(2)의 거는 걸림부(1a)와, 타측은 상기 톱날(2)을 후방으로 긴장시켜 체결하는 조임부(1b)로 이루어진 것이 대부분으로 양측의 고정봉(111)(131)에 톱날(2)의 구멍(20)을 끼워넣고 그 위치를 잘 유지시킨 상태에서 조임부(1b)를 긴장시키는 방법으로 사용되고 있으나, 이는 실질적으로 조임부(1b)의 나비너트(14)를 조이기 전까지 양측의 고정봉(111)(131)에 톱날(2)의 구멍(20)을 잘 맞추어 그 위치를 유지시키기가 매우 곤란한 문제점이 있었다.Typically, the hacksaw is fixed on both sides, one side is composed of a fastening portion (1a) of one side is fastened to the hook portion (2a) of the saw blade (2), the other side to tighten the saw blade (2) to the rear. Although the holes 20 of the saw blade 2 are inserted into the rods 111 and 131 and the position of the saw blade 2 is maintained well, the clamping portion 1b is used in a tensioned manner. Before tightening the butterfly nut 14, there was a problem that it was very difficult to maintain the position by fitting the holes 20 of the saw blade 2 to the fixing rods 111 and 131 on both sides.
즉, 일측과 타측에 톱날을 걸어 손으로 그 톱날을 잡고 반대 손은 나비너트를 조일때 쇠톱대가 지지되는 곳이 없기 때문에 허벅지와 가슴 사이에 쇠톱대를 지지하거나, 또는 벽면을 이용하는 등의 난해한 방법이 필요하며, 또한 상기 방법은 손을 쉽게 다칠수 있을 뿐 아니라, 양측의 톱날을 잘 맞추어 너트를 조일려고 하면 양측의 톱날 중 한쪽이 빠지는 등의 매우 짜증나는 경우가 많았던 것이다. In other words, hang the saw blade on one side and the other side, hold the saw blade with your hand, and the other hand is difficult to support the hacksaw between the thigh and chest, or use the wall because there is no place where the hacksaw is supported when tightening the butterfly nut. In addition, the method is not only easy to hurt the hand, but also try to tighten the nut to fit the saw blades on both sides was very annoying, such as one of the two saw blades fall out.
이에 본 고안은 상기와 같은 종래의 문제점을 해소하고자 안출된 것으로서, 쇠톱대 조임부의 장착대를 전방으로 소정의 탄성을 가지게 하므로서 일측은 톱날을 걸고 타측은 상기 장착대를 탄성으로 밀어 톱날을 긴장시킨 상태로 쉽게 톱날이 이탈되지 않게 하므로서 용이하게 톱날을 장착할 수 있게 한 것인데, 이를 첨부된 도면에 의거 보다 상세하게 설명하면 다음과 같다. The present invention has been devised to solve the conventional problems as described above, so that one side to the saw blade and the other side to push the mounting rod elastically to tension the saw blade while having a predetermined elasticity forward to the mounting bracket of the claw saw fastener. It is to be able to easily install the saw blade so that the saw blade is not detached in a state that is made, according to the accompanying drawings in more detail as follows.
일측은 톱날(2)의 거는 걸림부(1a)와, 타측은 상기 톱날(2)을 후방으로 긴장시켜 체결하는 조임부(1b)로 이루어진 공지된 쇠톱대(1)에 있어서, In the well-known hacksaw stand 1 which consists of a fastening part 1a of the saw blade 2 which hangs on one side, and the fastening part 1b which tightens and tightens the saw blade 2 to the rear side,
상기 조임부(1b)를 전방이 개방된 다각형의 장착공(121)을 형성하여, 그 후부에는 삽입공(122)으로 형성된 장착프레임(12)을 구비하고, The fastening part 1b forms a mounting hole 121 having an open front in the front, and a rear mounting frame 12 formed of the insertion hole 122,
상기 다각형의 장착공(121)에는 전방이 톱날(2)을 고정하는 고정봉(131)으로 구성되고, 그 후부는 다각형의 장착편(132)과 나사봉(133)으로 이루어진 장착대(13)를 삽입하되, 상기 나사봉(133)에 스프링(13a)을 끼워넣어 전방으로 소정의 탄성으로 가지도록 장착하여 나비너트(14) 등으로 체결하므로서, 톱날(2)을 완전히 조이기 전까지 쇠톱대(1)에서 상기 톱날이 쉽게 이탈되지 않게 한 쇠톱대의 톱날 이탈방지 긴장구조를 제공한다 The mounting hole 121 of the polygon is composed of a fixed rod 131, the front fixed to the saw blade (2), the rear portion of the mounting base 13 consisting of a polygonal mounting piece 132 and a screw rod 133 Insert the spring 13a into the screw rod 133 and mount it so as to have a predetermined elasticity forward and fasten it with the butterfly nut 14 or the like, so that the saw blade 2 is completely tightened until the saw blade 2 is tightened. It provides a saw blade anti-tension tension structure of the hacksaw to prevent the saw blade from detaching easily
즉, 본 고안은 상기 다각형의 장착공(121) 내의 삽입공(122)과 장착편(132) 사이의 나사봉(133)에 스프링(13a)을 탄설하므로서 소정의 탄성을 전방으로 가지게 되며, 이로 인해 톱날(2)을 가설 할 때, 상기 장착대(13)에 톱날(2)의 일측을 걸고 반대측에 톱날(2)의 타측을 걸어 그 탄성으로 두 위치를 유지시킬수 있기 때문에 쇠톱대(1)에 톱날(2)을 완전히 장착하기 전 톱날(2)이 쉽게 이탈되는 것을 방지할 수 있게 한 것이다. In other words, the present invention has a predetermined elasticity forward by arranging the spring 13a in the threaded rod 133 between the insertion hole 122 and the mounting piece 132 in the mounting hole 121 of the polygon, thereby When placing the saw blade (2) due to the claw pole (1) because it is possible to hang the one side of the saw blade (2) to the mounting table 13 and the other side of the saw blade (2) on the opposite side to maintain the two positions by its elasticity It is to prevent the saw blade (2) from easily detached before the saw blade (2) is completely mounted on.
이와 같이 구성된 본 고안은 쇠톱대에 톱날을 완전히 조이기 전 스프링의 탄성으로 톱날을 가설한 후 완전하게 조일수 있게 하므로서, 상기 톱날이 탄성에 의해 이탈되지 않고 그 위치를 일정히 유지시킬수 있기 때문에 종래와 같이 난해한 방법으로 톱날의 위치를 유지시키지 않아도 되므로 톱날의 장착이 쉽고 간편한 이점이 있다. The present invention configured as described above allows the saw blade to be completely tightened after elasticity of the spring before the saw blade is completely tightened to the hacksaw, so that the saw blade can be kept constant without being separated by elasticity, as in the prior art. Since it is not necessary to maintain the position of the saw blade in a difficult way, the mounting of the saw blade is easy and convenient.
