[0030] In this embodiment, when the operator uses the water life-saving stretcher, the rescuer first opens the inflation valve 2 by connecting the remote control 6, so that the inflation gas generated by the gas generator in the sealed cabin 5 is successively transported to the inner cavity of the foldable floating air raft 1 through the hose and the inflation valve 2, so that the foldable floating air raft 1 is quickly filled and unfolded. The rescuer uses the remote control 6 to move the foldable floating air raft 1 to the position of the victim in the water. If the victim is conscious, he can be carried on the foldable floating air raft 1 by himself. If the victim is unconscious, the rescuer needs to go into the water to lift the victim onto the foldable floating air raft 1, pull one end of the widened binding rope 721 out of the inner cavity of the square placement box 711, and bind the patient to the foldable floating air raft 1 by the widened binding rope 721. The magnetic plug 722 at the other end of the widened binding rope 721 is inserted into the inner cavity of the hollow fixed magnetic cylinder 723. The hollow fixed magnetic cylinder 723 is fixedly installed in advance at the two ends of the other side of the foldable floating air raft 1. Then the lifeguard controls the foldable water lifesaving stretcher back to the safe area through the remote control 6. At this point, a rescue work is completed. When the widened binding rope 721 is working, the use length of the widened binding rope 721 can be adjusted according to the body shape of the victim. After determining the use length of the widened binding rope 721, the arc-shaped threaded rod 732 is pushed to drive the pressing block 731 to press one end of the widened binding rope 721 against the inner wall of the square placement box 711 for fixation. By rotating the rotating ring 735, the fixing nut 734 can be driven to fix the moving position of the arc-shaped threaded rod 732.

[0031] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 3-4 The retracting assembly 8 includes a fixed long rod 81 and an H-shaped sleeve 82 movably mounted on the outer surface of the fixed long rod 81. Round rods 83 are fixedly mounted around the outer walls of both ends of the H-shaped sleeve 82. An expansion ring 84 is fixedly mounted on one end of the round rod 83. The fixed long rod 81 is fixedly mounted in the inner cavity of the square placement box 711. A widened binding rope 721 is wound around the outer surface of the H-shaped sleeve 82 for multiple turns. One end of the widened binding rope 721 passes through a half groove opened on one side of the upper end of the square placement box 711. One side of the outer wall of the expansion ring 84 is movably mounted in the inner cavity of the penetration groove 712.

[0032] In this embodiment, when the rescuer is not using the widened binding rope 721 , the rescuer can rotate the expansion ring 84 on one side of the inner cavity of the penetration groove 712 so that the expansion ring 84 drives the widened binding rope 721 to rotate in the opposite direction, thereby retracting the widened binding rope 721 .

[0033] Working principle: When the operator uses the water life-saving stretcher, the rescuer first opens the inflation valve 2 by connecting the remote control 6, so that the inflation gas generated by the gas generator in the sealed cabin 5 is successively transported to the inner cavity of the foldable floating air raft 1 through the hose and the inflation valve 2, so that the foldable floating air raft 1 is quickly filled and unfolded. The rescuer uses the remote control 6 to move the foldable floating air raft 1 to the position of the victim in the water. If the victim is conscious, he can be carried on the foldable floating air raft 1 by himself. If the victim is unconscious, the rescuer needs to go into the water to lift the victim onto the foldable floating air raft 1, and pull one end of the widened binding rope 721 out of the inner cavity of the square placement box 711, and bind the patient to the foldable floating air raft 1 through the widened binding rope 721, and then insert the magnetic plug 722 at the other end of the widened binding rope 721 into the inner cavity of the hollow fixed magnetic cylinder 723, and then the air is filled. The central fixed magnetic cylinder 723 is fixedly installed in advance at the two ends of the other side of the foldable floating air raft 1, and then the lifeguard controls the foldable water life-saving stretcher to return to the safe area through the remote control 6, and the rescue work is completed. When the widened binding rope 721 is working, the use length of the widened binding rope 721 can be adjusted according to the body shape of the victim. After determining the use length of the widened binding rope 721, the arc-shaped threaded rod 732 is pushed to drive the pressing block 731 to press one end of the widened binding rope 721 against the inner wall of the square placement box 711 for fixing. By rotating the rotating ring 735, the fixing nut 734 can be driven to fix the moving position of the arc-shaped threaded rod 732. After using the widened binding rope 721, the expansion ring 84 on one side of the inner cavity of the penetration groove 712 can be rotated, and the expansion ring 84 drives the widened binding rope 721 to rotate in the opposite direction to retract the widened binding rope 721.
