The utility model discloses a screw taking-out device, which belongs to the technical field of aeronautical manufacturing and maintenance and comprises a sleeve, a locking ring, a cylindrical rolling shaft and the like, the cross section of an inner hole of the sleeve is a triangle-like shape formed by connecting three linear sections and three arc sections at intervals, the locking ring is provided with three strip-shaped cylindrical rolling grooves, and the cylindrical rolling shaft is arranged in the cylindrical rolling grooves. And the two are combined and then placed and limited in the inner hole of the sleeve. During use, the screw rod is inserted among the three cylindrical rolling shafts in the locking ring, the outer sides of the cylindrical rolling shafts are adjacent to the arc section of the inner hole in a non-extrusion state, the sleeve is rotated, the cylindrical rolling shafts slide to the linear section of the inner hole under the friction force action of threads of the screw rod, the screw rod is clamped by the cylindrical rolling shafts, and the sleeve is continuously rotated to screw out the screw rod. When the screw rod is disassembled, torque applied to the screw rod acts on the axis of the screw rod, the screw rod is prevented from being broken in the rotating and taking-out process, the quality of a product fastened by a bolt is guaranteed, and meanwhile the disassembling work efficiency is not affected.
