The carrying case 18 will swing if it encounters wind during use; when one 18 of the first carrying device 6 and the second carrying device 8 swings more than the other 18, the ring buckle 56 of the second carrying device 8 may not be engaged with the detachable hook 19 of the first carrying device 6, i.e. the first carrying device 6 and the second carrying device 8 are not connected together; this makes it possible to cause the first 6 and second 8 carriers to collide; causing injury to persons located in the first 6 and second 8 carriers. Therefore, in the present invention, when the swing amplitude of one carrying box 18 of the first carrying device 6 and the second carrying device 8 is larger than that of the other carrying box 18, the swing amplitude of the swing block 37 in the carrying box 18 with large swing amplitude under the action of the corresponding steel rope 3 is also increased; at this time, the swinging block 37 brings one of the two trigger plates 38 mounted thereon into contact with the corresponding swinging rod 46 and swings the swinging rod 46; the swinging of the swinging rod 46 causes the rack bar 41 and the other swinging rod 46 to swing; the latch rack 41 moves upward while swinging under the action of the two swing levers 46; the rack gear 41 moves upward to be disengaged from the corresponding second gear 45; at this time, the rack-and-pinion 41 loses the binding with the second gear 45; i.e. the rack of catches 41 has lost its grip on the second winding wheel 48; the second winding wheel 48 is rotated by the wire 3 wound around the second winding wheel 48; the second winding wheel 48 rotates to release the steel cord 3 wound thereon; that is, the length between the steel cord 3 connected to the second winding wheel 48 and the steel cord 3 wound on the corresponding first winding wheel 2 is increased; at this time, the bearing box 18 with larger swing amplitude moves downwards under the action of self gravity; the carrying boxes 18 in the first carrying device 6 and the second carrying device 8 are contacted and connected with each other during the moving process; swinging together; the first bearing device 6 and the second bearing device 8 are prevented from impacting in the swinging process; when the first bearing device 6 and the second bearing device 8 are connected together, the swing amplitude of the swing block 37 in the bearing box 18 with larger swing amplitude is reduced; meanwhile, the swing rod 46 in the bearing box 18 is restored to the original position under the action of the volute spiral spring 47, and the second gear 45 is limited again; i.e. again limiting the second winding wheel 48.

When the ring-shaped buckle 56 in the second bearing device 8 is completely matched with the detachable hook 19 in the first bearing device 6, the first bearing device 6 and the second bearing device 8 are connected together and swing at the same time; the first bearing device 6 and the second bearing device 8 are prevented from being impacted in the swinging process; causing injury to persons located in the first 6 and second 8 carrier devices; if the amplitude of the swing of one of the carrying boxes 18 in the first carrying device 6 and the second carrying device 8 is larger than that of the other carrying box 18 in the swing process, the swing amplitude of the swing block 37 in the carrying box 18 with large swing amplitude under the action of the corresponding steel rope 3 is also increased; at this time, the swinging block 37 brings one of the two trigger plates 38 mounted thereon into contact with the corresponding swinging rod 46 and swings the swinging rod 46; the swinging of the swinging rod 46 causes the rack bar 41 and the other swinging rod 46 to swing; the latch rack 41 moves upward while swinging under the action of the two swing levers 46; the rack gear 41 moves upward to be disengaged from the corresponding second gear 45; at this time, the rack-and-pinion 41 loses the binding with the second gear 45; i.e. the rack of catches 41 has lost its grip on the second winding wheel 48; the second winding wheel 48 is rotated by the wire 3 wound around the second winding wheel 48; the second winding wheel 48 rotates to release the steel cord 3 wound thereon; that is, the length between the steel cord 3 connected to the second winding wheel 48 and the steel cord 3 wound on the corresponding first winding wheel 2 is increased; at this time, the bearing box 18 with larger swing amplitude moves downwards under the action of self gravity; the carrying boxes 18 in the first carrying device 6 and the second carrying device 8 are contacted and connected with each other during the moving process; swinging together; the first bearing device 6 and the second bearing device 8 are prevented from impacting in the swinging process; when the first bearing device 6 and the second bearing device 8 are connected together, the swing amplitude of the swing block 37 in the bearing box 18 with larger swing amplitude is reduced; meanwhile, the swing rod 46 in the bearing box 18 is restored to the original position under the action of the volute spiral spring 47, and the second gear 45 is limited again; i.e. again limiting the second winding wheel 48.
