Folding ladder

A folding ladder, comprising:

• a rear frame,
• a front frame, rotatably connected with the rear frame,
• a pedal, rotatably connected with the front frame;
• and
• a locking mechanism, comprising a hook member, a snap portion capable of being engaged with the hook member, and a control member that controls disengagement of the hook member and the snap portion, wherein the snap portion is disposed at the pedal, and the hook member is fixed to the rear frame;
• wherein the rear frame is provided with a crossbar and the pedal is capable of being flipped to the crossbar, and after the pedal is flipped to the crossbar, the locking mechanism locks the pedal;
• wherein a part of the hook member extends out to form a driving rod, the folding ladder further comprises a first elastic member, when the control member moves toward the driving rod by overcoming resistance of the first elastic member, the control member exerts a force on the hook member, so that the hook member is disengaged from the snap portion, and then the first elastic member exerts a force on the control member to reset the control member;
• and
• wherein the folding ladder further comprises a second elastic member configured to keep the hook member in a locked state, and the second elastic member is connected to the hook member;
• and
• wherein when the folding ladder is unfolded, the snap portion and the hook member are located under an upper surface of the pedal, the control member is vertically and movably disposed on the pedal, and a press surface of the control member is parallel to the upper surface of the pedal, such that the control member is pressed to move vertically to release the hook member.
