Claim 0:
1. A rowing exercise machine, comprising:
a base frame, including a slidable seat;
a paddle unit, pivotally connected to the base frame;
a first rotating shaft, pivotally connected to the base frame in a first axial direction;
a paddle linkage unit, disposed on the base frame, the paddle linkage unit including a paddle linkage member, a paddle one-way driving wheel and a paddle reel, the paddle linkage member connecting the paddle unit and the paddle one-way driving wheel, the paddle one-way driving wheel being pivotally connected to the first rotating shaft, the paddle one-way driving wheel driving the first rotating shaft in a first rotational direction, the paddle one-way driving wheel being idle on the first rotating shaft in a second rotational direction, the paddle reel being connected to the paddle one-way driving wheel;
a resistance unit, disposed on the base frame, the resistance unit being connected to the first rotating shaft for providing a rotational resistance to the first rotating shaft;
a pull bar unit, disposed on the base frame;
a second rotating shaft, pivotally connected to the base frame in the first axial direction;
a pull bar linkage unit, disposed on the base frame, the pull bar linkage unit including a pull bar linkage member, a pull bar transmission wheel, a pull bar one-way wheel, a pull bar reel and a pull bar driving wheel, the pull bar transmission wheel being connected to the second rotating shaft, the pull bar one-way wheel being pivotally connected to the second rotating shaft, the pull bar one-way wheel driving the second rotating shaft in the first rotational direction, the pull bar one-way wheel being idle on the second rotating shaft in the second rotational direction, the pull bar reel being connected to the second rotating shaft, the pull bar driving wheel being connected to the first rotating shaft, the pull bar unit being connected to the pull bar transmission wheel through the pull bar linkage member;
wherein when a first operating force is applied to the paddle unit, the paddle one-way driving wheel and the first rotating shaft are driven to rotate in the first rotational direction, and the paddle reel accumulates a first return force; when the first operating force decreases or disappears, the first return force drives the paddle one-way driving wheel to be idling on the first rotating shaft in the second rotational direction;
wherein when a second operating force is applied to the pull bar unit, the pull bar transmission wheel, the pull bar one-way wheel, the second rotating shaft and the pull bar driving wheel are driven to rotate in the first rotational direction together with the first rotating shaft, and the pull bar reel accumulates a second return force; when the second operating force decreases or disappears, the second return force drives the pull bar one-way wheel to be idling on the second rotating shaft in the second rotational direction.
