The invention relates to the field of picking appliances, in particular to a picking ladder capable of being used in a terrace. The picking ladder comprises a supporting rod, wherein a plurality of transverse rods which are perpendicular to the supporting rod are arranged on the supporting rod; the lower end of the supporting rod is fixedly connected with an upper panel; the supporting rod is further connected with a plurality of stress rods; the upper ends of the stress rods are connected with the supporting rod; the lower ends of the stress rods are connected with the upper end of the upper panel; a lower panel which is parallel to the upper panel is further arranged below the upper panel; a tire is arranged between the upper panel and the lower panel and is fixedly connected with the upper panel and the lower panel; a plurality of inclined positioning rods are further arranged at the lower end of the lower panel; and the upper ends of the positioning rods are hinged to the lower panel. By the picking ladder, the problem that an existing ladder cannot be used in the terrace stably can be solved.
