The invention discloses a hook-grappling video underwater searching and rescuing device and relates to a searching and rescuing tool. The front end of a telescopic rod is connected with a hook rod, wherein a hook is arranged at the front end of the hook rod; a pressing tongue is arranged on the hook rod and cooperates with the hook to clamp and grapple; the pressing tongue is jointly controlled by a towing device and a returning spring; the pressure tongue, the pressure tongue towing device and the returning spring are structurally characterized in that a hole is formed in the hook rod; a shaft is arranged in the hole; the middle part of the pressing tongue is fixed to the shaft to form a lever; the left end of the pressing tongue is connected to the hook rod by virtue of the returning spring; the right end of the pressing tongue is connected to the towing device; and the right end of the pressing tongue which is not towed by a rope is pressed onto the hook under the action of the returning spring at the left end. The hook-grappling video underwater searching and rescuing device has the beneficial effects that the telescopic rod is adopted, so that the rescue range is widened; by virtue of the design of the hook, the surface rescue is superior to the rope and a bamboo pole; a video lighting device is additionally arranged, the underwater searching and rescuing are facilitated; the pressing tongue and the hook cooperate to tow drowning persons; and by virtue of lightweight and convenient design, the device is convenient to operate.
