The invention discloses a salvage tool, and relates to the technical field of ship engineering. The salvage tool provided by the invention comprises the following parts: a main rod which is hollow; ananchor hook that comprises a plurality of claws, and the claws are bent and hollow, wherein each claw is communicated with one end of the main rod; the plurality of claws are symmetrically distributed relative to the center of the main rod in a plane perpendicular to the main rod; a gap is reserved between the end, away from the main rod, of the anchor hook and the main rod. The salvage tool alsohas: a sealing cover mounted at the end, away from the anchor hook, of the main rod; a closed cavity formed among the sealing cover, the main rod and the anchor hook; a ballast filled in a cavity formed by the bottom of the main rod and the anchor hook, so that the bottom of the salvage tool is in a gravity concentration area; and a handrail rope with one end connected with one end, away from theanchor hook, of the main rod. By adding the filler, the sinking gravity of the salvage tool is increased under the condition that the size of the salvage tool is kept unchanged, and the salvage efficiency is improved; the claw shape and the claw linear transition are reasonably bent, and the reliability of rope grabbing is guaranteed.
