Abstract
An assembled ladder is formed by coupling a top ladder segment, a plurality of middle ladder segments, and a plurality of bottom ladder segments together. The bottom ladder segments include a ladder body, support frame assemblies, ancillary frames, adjustable support pads, and adjustable coupling members. The support frame assemblies are respectively set at two sides of the ladder body. The ancillary frames are mounted to the support frame assembly. The adjustable support pads are screwed to the ancillary frames. The adjustable coupling members have an end coupled to the support frame assemblies and are partially received in the receiving space. With the adjustable coupling members fixing the support frame assemblies, the ancillary frames are expanded. Through adjustment made with the adjustable support pads, the ladder can be set more stably to achieve safety and convenience of use.
