The present invention discloses a vegetation pruning device comprising a cutting element a guide bar for supporting the cutting element, the guide bar having a guide bar plane, the guide bar being pivotable in the guide bar plane about a fixed axis a motor having a motor shaft for rotatably driving the cutting element a motor housing for receiving the motor a guiding mechanism connected to the motor housing, the guiding mechanism having a longitudinal axis a handle assembly operable to move linearly along the longitudinal axis, a transmission device for connecting the handle assembly to the guide bar through, the transmission device converting a linearly movement of the handle assembly to a pivoting movement of the guide bar, the cutting element thereby approaching or withdrawing from a workpiece to be sawn the transmission device is associated with the motor and operable to drive the motor and guide bar to move together. The handle assembly is moving linearly, which makes the operator feel comfortable in any working instance.
