According to the present invention, since a driving unit generating linear reciprocating force required for sawing and a saw blade holder where a saw blade is installed are dualized so that a structure is improved to transmit the linear reciprocating force through an extension bar, the center of gravity of the high-place working saw is biased toward an operator, thereby enabling the operator to freely move the position of the saw blade with little force during high-place sawing. In particular, since the extension bar is segmented to be assembled by simple operation, excellent portability is provided and the linear reciprocating force is transmitted without loss. The high-place working saw comprises a driving unit (100), an extension bar (200), a guide module (300), and a saw blade holder (400).

As the structure is improved to transmit this, the center of gravity of the high saw saw is biased toward the operator, so the position of the saw blade can be moved freely even with little force during high altitude sawing. It relates to a high-speed saw having a dual structure in which a driving unit and a saw blade holder through which moving force is transmitted without loss.

통상적으로 톱은 강철로 된 얇은 톱양에 날카로운 이가 형성되고, 길이방향으로 직선 왕복운동력에 의해 날카로운 이가 나무를 포함하는 피절삭물을 절삭하는 장치로서, 주로 과수 가지치기, 가로수 가지정리, 산림 숲 가꾸기 사업을 포함하는 고소 작업용도로 널리 사용되고 있지만, 원거리에 피절삭물을 수작업으로 톱질함에 있어 많은 힘이 소요됨과 더불어 장시간 작업이 불가능한 실정이다.In general, a saw is a device that has sharp teeth on a thin saw made of steel, and cuts a cutting object including a tree with sharp teeth by a linear reciprocating force in the longitudinal direction. Although it is widely used for high-altitude work including business, it takes a lot of power to manually saw a workpiece from a distance, and it is impossible to work for a long time.
