Leg lift machine

A leg lift machine comprising:

• a base unit, a main handle unit, two drive levers, two pedals, and a linkage mechanism;
• wherein:
• the base unit includes a first stand, a second stand, two third stands, a first transverse rod, and a second transverse rod;
• the first transverse rod is configured to be placed on the ground;
• the second transverse rod is configured to be placed on the ground;
• the first stand has a lower end secured to the first transverse rod;
• the second stand has a lower end secured to the second transverse rod;
• the second stand has an upper end foldably and pivotally connected with a middle position of the first stand;
• each of the two third stands has an upper end foldably and pivotally connected with an upper end of the first stand;
• the two third stands are arranged at two sides of the first stand;
• the main handle unit has a lower end securely connected with a front section of the first stand;
• the main handle unit has an upper end provided with a handgrip;
• each of the two drive levers has an upper end pivotally connected with one of the two third stands and serves as a rotation fulcrum;
• the two drive levers reciprocally swing forward and backward and move along a curved trajectory;
• each of the two pedals is pivotally connected with a lower end of one of the two drive levers;
• the linkage mechanism includes a swing base and two linkage rods;
• the swing base is pivotally mounted on the two third stands and symmetrically swings leftward and rightward;
• each of the two linkage rods has a lower end pivotally connected with one of two ends of the swing base;
• each of the two linkage rods has an upper end pivotally connected with the upper end of one of the two drive levers;
• and
• the two drive levers are limited by the swing base and the two linkage rods to reciprocally swing forward and backward.
