A second handle includes a cutting saw unit moving a saw chain (30) in an unlimited orbit form by a motor (M) on the front side. The first and second handles rotates around a central hinge shaft (400). A first bevel gear (21a) installed on a motor shaft (21) of the motor, and a second bevel gear (22a) installed on a rotary shaft (22) on the same center with the hinge shaft are coupled. The saw chain is formed on a driving sprocket (23) of the rotary shaft and an interlocking sprocket on a front interlocking shaft. The interlocking shaft is combined to the tip-end of a guide bar (26) which is assembled to a front assembling unit (211) of a central main body of the second handle. The guide bar is formed of the front assembling unit, a guide groove, and a guide protrusion. A coupling bolt (27) assembled to a nut (28) one side of the guide bar is combined to a supporting jaw (213) of the front assembling unit. |
