The invention discloses an arranging device for arranging secretarial data, and belongs to the technical field of secretarial appliances. The arranging device comprises a stabilizing plate, wherein the top of the stabilizing plate is fixedly connected with a concave frame, the two sides of the inner wall of the concave frame are each provided with two first sliding grooves, the four first slidinggrooves are each internally connected with a first sliding block in a sliding mode, every two first sliding blocks form a group, and the opposite sides of the first sliding blocks of each sets of arefixedly connected with a same movable plate. Through the combined action of a motor, a bearing, a rotating shaft, a two-way threaded rod, a threaded cap, a second sliding groove, a second sliding block, a movable rod, the movable plates and a fixed plate, arranged data can be flattened, through the arrangement of a telescopic assembly and the fixed plate, the data placed on the stabilizing plate can be fixed, through the arrangement of a second groove and a third groove, when flattening is conducted, the telescopic assembly can be completely stored in the second groove and the third groove, and therefore the fixed plate can be evenly stressed to flatten the data.
