The application relates to a pull operating apparatus. The pull operating apparatus comprises a clamping jaw for clamping or releasing a target object, a plurality of driving ropes, a plurality of sheath tubes, a spring tube, and an outer sleeve tube, wherein the driving ropes are connected with the clamping jaw to drive the clamping jaw to turn and open or close, the sheath tubes sleeve the peripheries of the driving ropes and are in one-to-one correspondence with the driving ropes which can move relative to the sheath tubes in the axial direction, the sheath tubes are contained in the springtube which has elasticity, and the outer sleeve tube sleeves the periphery of the spring tube. In the pull operating apparatus, by arranging the spring tube between the sheath tubes and the outer sleeve tube, the problem that the outer sleeve tube is easily bent at an angle when a gap exists between the sheath tubes and the outer sleeve tube is solved, the diameter of the pull operating apparatusis greatly reduced, the friction force between the sheath tubes and the outer sleeve tube is reduced, and the operability of the pull operating apparatus is improved.
