Abstract | The present invention relates to an electric hammer, wherein a motor is located between a front handle and a rear handle such that the center of gravity of the electric hammer may be located between both gripping hands. Therefore, the user may feel the electric hammer to be lighter, and the entire length of the electric hammer may be configured to be shorter. To this end, the electric hammer according to the present invention, which can be converted into a drill mode, a hammer mode, and a hammer drill mode, and in which a motor is located between the front handle and the rear handle, may comprise: a cylinder which accommodates a piston applying an impact to a bit; a driving power delivering shaft which delivers the driving power of a motor in a back-and-forth reciprocating movement of a piston, a rotating movement of the cylinder, or both of the back-and-forth reciprocating movement of the piston and the rotating movement of the cylinder; and a motor which is located under the power delivering shaft and delivers driving force to a length middle portion of the power delivering shaft.
본 발명은 전동햄머에 관한 것으로서, 특히 전방 손잡이와 후방 손잡이의 사이에 모터가 위치하여 전동햄머의 무게 중심이 파지하고 있는 양손 사이에 위치하여 보다 가볍게 느껴질 수 있도록 구성함과 더불어 전동햄머의 전체 길이를 보다 짧게 구성한 것이다. 상기와 같은 목적을 달성하기 위한 본 발명은 드릴 모드, 햄머 모드, 햄머드릴 모드로 전환이 가능하며 전방 손잡이와 후방 손잡이의 사이에 모터가 위치하는 전동햄머로서, 비트에 충격을 가하는 피스톤을 수용한 실린더와, 모터의 동력을 피스톤의 전후 왕복운동으로 전달하거나 실린더의 회전운동으로 전달하거나 상기 피스톤의 전후 왕복운동과 실린더의 회전운동으로 동시에 전달하는 동력전달축과, 동력전달축의 아래에 위치하며 동력전달축의 길이 중간부로 동력을 전달하는 모터를 포함하는 것을 기술적 특징으로 한다. |
