Description

Technical Field

[0001] The utility model relates to a rescue and salvage hook, belonging to the field of rescue and salvage tools. Background Art

[0002] When the area of ​​water is relatively large and the location of the drowned person or object is unclear, a water rescue and salvage hook is needed to expand the search range. When the water rescue and salvage hook hooks the drowned person or the object that has sunk to the bottom of the water, if the weight is relatively large, it is difficult for the rescue personnel to pull it out of the water. Therefore, an air bag is installed on the rescue and salvage hook. By filling the air bag with air, the buoyancy is conveniently used to pull the drowned person or the object that has sunk to the bottom of the water out of the water, thereby reducing labor intensity. Because a plurality of hook bodies are installed on the rescue and salvage hook, and the hook bodies are connected to the frame body by chains, the pointed heads on the hook bodies can easily pierce the air bags, and the convenience of use is poor.
