Foldable treadmill

A foldable treadmill, comprising a base, a rotational shaft, two supporting posts, and two handle bars;

• the rotational shaft is rotationally mounted at a frontal part of the base;
• the two supporting posts are fixedly connected to two ends of the rotational shaft respectively, and are also positioned on two sides of the base respectively;
• the two handle bars are hinged with top ends of the two supporting posts respectively;
• the two handle bars are foldable against the two supporting posts respectively, and the two supporting posts are foldable against the base;
• wherein:
• the foldable treadmill also comprises two seats and two sets of wire pulling mechanisms;
• the two seats are fixedly connected to the rotational shaft corresponding to the two supporting posts respectively;
• the two sets of wire pulling mechanisms comprise two wires and two pins, wherein each of the two sets of wire pulling mechanisms comprises a wire of the two wires and a pin of the two pins;
• the two pins of the two sets of wire pulling mechanisms are movably disposed at two side rods of the two sides of the base respectively;
• one end of the wire of one of the two sets of wire pulling mechanisms disposed corresponding to one of the two sides of the base is connected to a corresponding handle bar disposed also corresponding to a same side as said one of the two sides of the base, and another end of the wire of said one of the two sets of wire pulling mechanisms disposed corresponding to said one of the two sides of the base is connected to a corresponding pin disposed also corresponding to the same side as said one of the two sides of the base or to a corresponding pin disposed corresponding to another one of the two sides of the base;
• rotation of the two handle bars to achieve folding of the treadmill drive the two wires to pull the two pins;
• each of the two seats is provided with a position limiting hole which a corresponding pin is removably inserted, so that the two seats together with the rotational shaft achieve a fixed state or a rotatable state with respect to the base.
