Claim 0:
1. A reciprocating transmission structure of an exercise machine, mounted to a stationary frame of the exercise machine, comprising:
a first reciprocating member and a second reciprocating member each configured to perform a reciprocating vertical motion in a respective vertical plane parallel to a longitudinal axis of the stationary frame;
the first reciprocating member being configured with a first operating member, a single first reciprocating pivot portion, and a single first force-receiving portion spaced apart from the single first reciprocating pivot portion and pivotally coupled to the first operating member at a single pivotal point, the single first reciprocating pivot portion being installed on a shaft directly coupled to the stationary frame, thus forming a direct pivotal connection between the single first reciprocating pivot portion and the stationary frame, wherein a first pivot portion is provided between the single first reciprocating pivot portion and the single first force-receiving portion;
the second reciprocating member being configured with a second operating member, a single second reciprocating pivot portion, and a single second force-receiving portion spaced apart from the single second reciprocating pivot portion and pivotally coupled to the second operating member at a single pivotal point, the single second reciprocating pivot portion being installed on a second shaft directly coupled to the stationary frame, thus forming a direct pivotal connection between the single second reciprocating pivot portion and the stationary frame, wherein a second pivot portion is provided between the single second reciprocating pivot portion and the single second force-receiving portion;
a main rotating wheel pivotally connected to the stationary frame through a rotating shaft, the main rotating wheel including a first face and an opposing second face, the first face being provided with a first face pivot portion at a position away from the rotating shaft, the second face being provided with a second face pivot portion at a position away from the rotating shaft;
a first link, one end of the first link being pivotally connected to the first pivot portion, and another end of the first link being directly or indirectly pivoted to the first face pivot portion;
a second link, one end of the second link being pivotally connected to the second pivot portion, and another end of the second link being directly or indirectly pivoted to the second face pivot portion; and
a resistance wheel, pivotally connected to the stationary frame, the resistance wheel being directly or indirectly driven by the main rotating wheel;
wherein the single first reciprocating member reciprocally moves with the single first reciprocating pivot portion as an axis thereof, wherein the single second reciprocating member reciprocally moves with the single second reciprocating pivot portion as an axis thereof, wherein the first link and the second link drive the main rotating wheel to rotate with the rotating shaft as an axis thereof, and wherein the main rotating wheel drives the resistance wheel to rotate.
