개량 드라이버Improved driver

제1도는 본 고안의 일부를 생략한 사시도.1 is a perspective view omitting a part of the present invention.

제2도는 본 고안의 요부에 대한 부분 단면도.2 is a partial cross-sectional view of the main part of the present invention.

제3도는 본 고안의 사용상태 부분 단면도.3 is a partial cross-sectional view of the state of use of the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 드라이버 2 : 사각돌부1: driver 2: square protrusions

3 : 돌부3: protrusion

본 고안은 "+"자형 드라이버의 선단부 중앙에 사각형 돌부를 형성하여된 개량드라이버에 관한 것이다.The present invention relates to an improved driver formed by forming a rectangular protrusion in the center of the tip of the "+" shaped driver.

종래의 드라이버는 "-"자형과 "+"자형으로 된 홈붙이 나사에 삽착되게 "-"자형과 "+"자형으로 돌설 형성되었는바, 홈에 삽착하는 드라이버의 괘지면이 협소하므로 인하여 강한 힘을 필요로 하면서 나사를 나착하거나 나해할 경우에는 드라이버의 선단부위가 비틀리거나 나사의 괘지홈부에 마찰되어 마모가 발생되는 드라이버는 물론 나사의 괘지홈 자체가 마모 및 망가지는 등의 사례가 빈번하였으므로 본 고안에서는 이러한 종래의 폐단을 감안하여 안출한 것으로 드라이버의 선단부위에 드라이버 지름내에 위치되게 사각의 돌부를 돌설하되, 이의 모서리부에는 사방으로 +자홈 머리나사의 가장자리부에 삽착되는 돌부를 다수곳으로 연설하여 역시 사각돌부가 삽착되게 사각 요입홈이 형성된 나사등에 사용함에 따라서 나해 및 나착에 따른 힘을 배가 될수 있게한 것으로 첨부도면에 의거하여 상세한 설명을 하면 다음과 같다.Conventional drivers are protrudingly formed into "-" and "+" shapes to be inserted into grooved screws of "-" and "+" shapes. When screwing in or screwing out with a need for force, there are frequent cases where the tip of the screwdriver is twisted or rubbed against the screw recess of the screw, causing wear and screwing, as well as the screw recess of the screw itself. In the present invention, in consideration of such a conventional closed end, the rectangular protrusion is projected to be located within the diameter of the driver at the tip of the driver, but the corner portion is provided with a plurality of protrusions inserted into the edge of the + head groove screw in all directions. As a result, it is used for screws, etc., in which square recesses are formed so that the square protrusions can be inserted. When the number of the detailed description based on the accompanying drawings, that allows the following:

드라이버(1)의 선단부위에 드라이버(1)원지름 내에 위치되게 사각돌부(2)를 돌설하되, 이의 모서리 하부에는 사방으로 돌부(3)을 드라이버(1)와 일체로 연설하였다.The square protrusion 2 protrudes from the tip of the driver 1 so as to be located within the diameter of the driver 1, but the protrusion 3 is integrally addressed with the driver 1 in all directions below the corner.

이와 같은 구성으로된 본 고안의 사용상태 및 효과에 있어서, 본 고안으로된 드라이버가 이에 맞게 형성된 홈붙이 나사에 삽착되는 부위는 제3도와 같이 드라이버(1) 선단의 사각돌부(2)외에도 이의 모서리 다수곳으로 연설한 돌부(3) 상에도 홈붙이 나사의 +자형으로 요설한 홈의 가장자리면과 삽착되므로 힘이 전달되는 부위는 양측으로 분산됨과 동시에 이에 따라서 강력한 힘으로 나사등을 나해 및 나착할수 있게 된 것으로 적은 힘으로도 많은 힘을 전달함은 물론 드라이버 및 나사의 훼손을 방지하게 된 효과적인 고안이다.In the state of use and effect of the present invention having such a configuration, the part of the screwdriver is inserted into the grooved screw formed according to the present invention is the corner of the other than the square protrusion 2 of the tip of the driver 1 as shown in FIG. On the protruding part 3, which is addressed to a large number of places, the groove is inserted into the edge of the groove, which is concave with the + -shaped groove of the grooved screw, so that the force is distributed to both sides and accordingly, the screw can be screwed out and screwed out with strong force. It is an effective design that transmits a lot of force with less force and prevents damage to the screwdriver and screws.
