The elasticity of the second spring 27 can drive the locking frame 19 to quickly and stably insert into the locking sleeve 18, realizing a convenient locking operation.
[0035] During use, in the initial state Figure 1 As shown, this is the usage state at this time, and the length can be adjusted according to the usage needs. When adjusting, the motor 7 is started to drive the bidirectional lead screw 8 to rotate, thereby driving the movable plate 9 to move. Under the action of the hinge arm 10, the fixed plate 11 drives the adjustment bracket 2 to move, thereby driving the extension bracket 3 to move, achieving the purpose of overall length adjustment. And when wading, the airbag 12 can be inflated, enabling it to float on the water surface as a whole during use. The binding ropes 5 on both sides can be tied to the arms of the rescue personnel to prevent the hands from detaching from the handle 4. When folding is required, first pull the sliding frame 15 to drive the cross socket 16 out of the cross slot. At this time, the support arm 13 is unlocked, and then the support arm 13 is rotated to the horizontal state. At this time, the handrail rod 14 will move and retract synchronously. Then release the sliding frame 15, and use the cross socket 16 to lock the support arm 13 again. Then pull the locking frame 19 to make the locking frame 19 disengage from the locking sleeve 18. At this time, the two fixed brackets 1 are unlocked, and then the two fixed brackets 1 can be rotated and folded and tied together by the binding ropes 5 on both sides to complete the storage and folding.
