The invention relates to the field of grab buckets, in particular to a size-adjustable grab bucket provided with two-stage bucket flaps. The grab bucket comprises a top plate, a pull rod, a first-grade grab bucket, a first-grade hydraulic rod, a second-grade grab bucket and a second-grade hydraulic rod, wherein the first-grade grab bucket comprises two sets of crescent first-grade bucket flaps; the tail parts of the first-grade bucket flaps are hinged to the pull rod; the other end of the first-grade hydraulic rod is fixedly provided with a fork connecting piece; the fork connecting piece is hinged to cross bars in the middle parts of the first-grade bucket flaps; the second-grade grab bucket comprises two sets of second-grade bucket flaps; the second-grade bucket flaps and the first-grade bucket flaps are staggered; the tail parts of the second-grade bucket flaps are hinged to the cross bars at the tail parts of the first-grade bucket flaps; the second-grade hydraulic rod is falciform; and one end of the second-grade hydraulic rod is hinged to the first-grade grab bucket, and the other end is hinged to cross bars in the middles of the second-grade bucket flaps. The size-adjustable grab bucket can use the first-grade grab bucket for grabbing objects with smaller diameters, and can jointly use the second-grade grab bucket and the first-grade grab bucket to grab objects with larger diameters, so that the applicability of the grab bucket to the sizes of the grabbed objects is effectively improved.
