when the drowning person is in the lifesaving range of the front protection clamp 87 and the rear protection clamp 11, the functional motor 82 is started, that is, under the power action of the functional motor 82, the driving shaft 81 rotates and drives the connecting bevel gear 59 to rotate, further drives the transmission bevel gear 60 to rotate, further drives the transmission shaft 62 to rotate, further drives the front gear 61 to rotate, further drives the front protection clamp 87 and the rear protection clamp 11 to fold under the meshing action of the rear gear 63, simultaneously drives the belt pulley 78 to rotate under the driving shaft 81, further drives the upper belt pulley 57 to rotate under the action of the belt 58, further drives the transmission shaft 56 to rotate, further drives the rotating rod 55 to rotate, under the rotating connecting action of the pushing rod 53, further drives the sliding rod 67 to move left and right in the inflating cavity 83, further drives the 65 to move left and right in the inflating cavity 83, and under the unidirectional action of the outer check valve 51 and the inner check valve 66 during the rightward movement of the 65, the external air enters the right end of the inflation cavity 83 through the long hose 14 through the outer one-way valve 51 and enters the left end of the inflation cavity 83 through the inner one-way valve 66, in the process that the 65 moves leftwards, the air at the left end of the inflation cavity 83 is pressed into the short hose 12 by the 65 and enters the air bag 29 to be inflated, further, in the process that the front protection clamp 87 and the rear protection clamp 11 are folded, the air bag 29 starts to be inflated, when the self-locking hook 48 on the front protection clamp 87 is buckled into the clamping groove 47 and self-locked under the action of the spring 49, the electromagnetic 79 is electrified, further, the connecting bevel gear 59 moves leftwards under the magnetic force of the electromagnetic 79 and is disengaged from the transmission bevel gear 60, further, the transmission bevel gear 60 stops rotating, further, the front gear 61 and the rear gear 63 stop rotating, at the moment, under the action of the spring 49, the self-locking hook 48 is self-locked in the clamping groove 47, meanwhile, the functional motor 82 does not stop rotating, namely the air bag 29 is always in an inflated state until the drowning person is clamped by the air bag 29; at this time, the upper electromagnetic spring 70 is energized, so that the driven bevel gear 69 slides downwards along the driven shaft 71 under the magnetic force of the upper electromagnetic spring 70 and is meshed with the input bevel gear 68, at this time, under the power action of the starting motor 76, the starting shaft 75 rotates and drives the input bevel gear 68 to rotate, further drives the driven bevel gear 69 to rotate, further drives the driven shaft 71 to rotate, further drives the turbine 72 to rotate, further drives the rotating shaft 36 to rotate, further drives the rotating rod 32 to rotate, further drives the projection 31, the function box 44, the front protection clamp 87, the rear protection clamp 11, the airbag 29 and drowning personnel in the airbag 29 to rotate upwards, safely conveys the drowning personnel to the upper surface of the lifesaving box 41, further pulls out the vent valve 30 upwards by the lifesaving personnel, discharges the air in the airbag 29, further pulls out the self-locking hook 48 from the clamping groove 47 to the right, so that the front protection clamp 87 is separated from the rear protection clamp 11, the person to be saved can now clear the binding of the front protective clip 87 and the rear protective clip 11 and wait for rescue on the matching floating plate 39.

In the above manner, a person skilled in the art can make various changes depending on the operation mode within the scope of the present invention.
