CONSTITUTION: The automatic machine comprises a base rod(1), a motor(2) equipped to one front side of the rod(1); a driving pulley(21) and a flywheel(22) mounted on an output axis protruded toward one side of the motor(2). The driving pulley(21) and an interlock pulley(31) mounted on an interlock shaft(3) are jointed by a belt. The interlock shaft(3) is provided with two chin gears at both sides of the shaft(3). One of the gears is connected to a large chain gear(51) on a longitudinal axis(4) by a chain(42). A chain gear(32) on the other side of the interlock shaft(3) is connected to another chain gear(51) of a transmission gear box(5) located to front lower portion of the base rod(1). A small gear(43) is equipped to an opposite side of the axis(4) and engaged with a large gear(61) contacting with a winch drum(6).
