Labor-saving foldable pedal

A labor-saving foldable pedal, comprising a footboard and a labor-saving rod, the labor-saving rod has a first end configured to be transversely hinged to a bicycle driving crank, and a second end of the labor-saving rod is longitudinally hinged to the footboard, wherein bearing limiting structures corresponding to each other are respectively provided at the second end of the labor-saving rod and a longitudinal hinge end of the footboard,

• wherein the bearing limiting structures include two first bosses disposed on the second end of the labor-saving rod and separated circumferentially when viewed longitudinally, and two second bosses disposed on the longitudinal hinge end of the footboard and separated circumferentially when viewed longitudinally,
• when the footboard is in an unfolded state and subjected to a treading force, a circumferential end of one of the first bosses contacts a circumferential end of one of the second bosses, a circumferential end of the other one of the first bosses contacts a circumferential end of the other one of the second bosses,
• the treading force forms a forcing couple on the two second bosses and a bearing couple on the two first bosses corresponding to the two second bosses.
