The invention provides a scissor ladder comprising at least two scissor units, wherein each scissor unit comprises a first scissor and a second scissor; the first scissor is of a central symmetry structure and comprises a first high pedal, a first low pedal and a first connecting part connected between the first high pedal and the first low pedal; the second scissor is of a central symmetry structure and comprises a second high pedal, a second low pedal and a second connecting part connected between the second high pedal and the second low pedal; the middle part of the first connecting part of one first scissor is hinged with the middle part of the second connecting part of one second scissor through a first limiting hinged part and a second limiting hinged part to form a scissor unit; and the upper scissor unit is connected with the lower scissor unit. The scissor ladder can be folded so as to be stored and carried.
