An opening and closing door is arranged on one side of a bin body, a plurality of storage racks are arranged in the bin body from top to bottom, first sliding grooves are formed in the two sides of the interior of the bin body, supporting plates are arranged on the two sides of each storage rack, first sliding blocks are arranged on the side faces of the supporting plates, and second sliding blocks are arranged on the side faces of the first sliding blocks. The first sliding blocks and the first sliding grooves are in sliding connection, and an adjusting part is arranged between every two adjacent storage racks and used for adjusting the distance between the two storage racks. When articles are placed in the storage racks, a gap between every two adjacent storage racks is locked according to the heights of the articles, so that the space utilization rate is increased, and the adjustment steps are as follows: a first rotary knob is rotated to drive a first transmission rod to rotate, two limiting seats are close to each other or separated from each other, and under the action of a transmission plate, the first rotary knob is rotated to drive a second transmission rod to rotate; and the height of the positioning plate is increased or decreased, so that the gap is adjusted to a proper size.
