여기서, 상기 스크류유입공간(S1)의 거리(L1)는 9mm로 상기와 같이 스크류유입공간(S1)이 커지게 되면 공급되는 5mm, 8mm, 14mm, 19.5mm의 다양한 스크류중 5mm와 8mm의 스크류는 무거운 스크류의 머리부분이 먼저 떨어지게 되는 스크류뒤집힘현상이 발생하게되는 문제점이 있다.Here, the distance (L1) of the screw inlet space (S1) is 9mm 5mm and 8mm of the various screws of 5mm, 8mm, 14mm, 19.5mm supplied when the screw inlet space (S1) increases as described above There is a problem that the screw flipping phenomenon that the head of the heavy screw falls off first.
둘째, 상기 몸체(10)와 상기 슈팅홀더(20)와의 결합이 나사선결합으로 이루어진다.Second, the coupling between the body 10 and the shooting holder 20 is made of screw coupling.
상기와 같은 나사선결합의 경우, 나사선의 경사 때문에 상기 비트통과홀(12)과 슈팅홀더결합홀(14)의 중심선이 이루는 중심각(α)과 상기 비트통과홀(12)과 상기 슈팅홀더결합홀(14)에 결합된 상기 슈팅홀더(20)가 이루는 사이각(β)이 어긋나는 경우가 발생된다.In the case of the screw coupling as described above, due to the inclination of the screw thread, the center angle α formed by the center line of the bit through hole 12 and the shooting holder coupling hole 14 and the bit through hole 12 and the shooting holder coupling hole ( A case where the angle β between the shooting holder 20 coupled to 14 is made to shift is generated.
즉, 상기 슈팅홀더(20)가 상기 슈팅홀더결합홀(14)과 어긋나게 결합될 경우, 상기 몸체(10)의 내부로 공급되는 스크류(1)의 축도 어긋나게 되는 문제점이 있다.That is, when the shooting holder 20 is coupled to the shooting holder coupling hole 14, the shaft of the screw 1 supplied into the body 10 is also displaced.
셋째, 상기 체결헤드(30)의 양측에 형성된 상기 조우(34)는 스크류(1)가 통과할 때 마다 횡 방향으로 180도씩 분리되고 결합됨으로써 상기 스크류를 2개의 방향에서 지지한다. 그러나, 2개의 조우(34)일 경우 스크류(1)가 통과할 때 회전축(38)을 기준으로 동일한 각도만큼 벌어지지 않고 하나의 조우가 더 많이 벌어지는 경우가 발생한다.Third, the jaws 34 formed on both sides of the fastening head 30 are separated and combined by 180 degrees in the transverse direction each time the screw 1 passes, thereby supporting the screws in two directions. However, in the case of two jaws 34, one jaw opens more than the same angle with respect to the rotation axis 38 when the screw 1 passes.
상기와 같은 문제점의 발생시 스크류(1)이 중심축은 틀어지고 상기 조립대상물(4)의 스크류홀과 결합시 스크류(1)는 끝까지 체결되지 못하고 저항이 발생되며, 승강 및 회전수단(도시 생략)에서는 스크류(1)의 체결과정이 끝난줄 알고 상기 전동비트(3)를 멈추게 된다.When the above problems occur, the central axis of the screw (1) is twisted and when combined with the screw hole of the assembly object (4) screw 1 is not fastened to the end, the resistance is generated, in the lifting and rotating means (not shown) Knowing that the fastening process of the screw 1 is finished, the electric bit 3 is stopped.
이 경우, 제품의 불량률이 높아지게 되는 결과를 초래하게 된다.In this case, the defect rate of the product is increased.
넷째, 상기 조우(34)의 외주면에 결합된 상기 조우결합링(36)이 일정한 위치에 놓여있지 않고 수시로 변하기 때문에 스크류(1)의 체결과정에서 2개의 조우(34)에 균일한 탄성력이 제공되지 않아 상기 조우(34)의 회전각도가 동일하지 않게 되는 문제점이 발생되고, 그로 인해 상기 스크류(1)의 축이 틀어지는 현상이 발생된다.Fourth, since the jaw coupling ring 36 coupled to the outer circumferential surface of the jaws 34 does not lie in a constant position and changes frequently, uniform elastic force is not provided to the two jaws 34 during the fastening process of the screw 1. Therefore, a problem occurs that the rotation angle of the jaws 34 is not the same, thereby causing a phenomenon that the shaft of the screw 1 is distorted.
