Portable multifunctional combined ladder
A portable multifunctional combined ladder comprises a pedal ladder and a telescoping ladder with telescoping function, one end of the pedal ladder and one end of the telescoping ladder are in connection via a rotation positioning mechanism, and different-angle rotation positioning of the pedal ladder relative to the telescoping ladder is realized through the rotation positioning mechanism; the pedal ladder comprises two vertical columns, a plurality of first pedal, and a second pedal whose pedal surface is larger than that of the first pedal; the first pedals form a revolute pair via a connection rod; the second pedal is arranged at one end, far away from the telescoping ladder, of the two vertical column via a turnover mechanism, and turnover positioning of the second pedal between the two vertical columns via the turnover mechanism is realized. The combined ladder possesses the advantages of being wide in applicability, safe, durable, simple in structure and convenient to use.
