The invention belongs to the technical field of aerospace, relates to an elastically-expansible multi-tube spiral inflatable gripper and solves the problems of the existing gripping mechanism for space targets. Spiral radius of the gripper in a spiral shape decreases gradually from the rear end to the front end. The gripper comprises an outer casing and a plurality of inner inflatable support core tubes; the inner inflatable support core tubes disposed within the outer casing support the outer casing; the spiral inner wall of the outer casing is made of elastic composite material; the elastic composite material comprises a woven layer and a nonslip layer sequentially from inside to outside; the woven layer is woven of rubber strips, so that the wove layer can elastically expand in all directions, or the woven layer is woven of rubber strips and aramid fiber, the rubber strips are arranged along the periphery of the outer casing, the aramid fiber is arranged axially along the outer casing, and thus the woven layer can expand along the periphery of the outer casing; the nonslip layer is made of nonslip rubber material; the spiral outside of the outer casing is provided with a coil spring. The gripper is used for gripping large-sized space targets.
