The connecting band 15 passes into the limiting hole 34, then winds around the connecting rod 33, and extends towards the water bag 11 where the connecting band 15 is located.

[0048] The connecting seat 31 is hingedly connected with the turnover plate 41 through the rotating shaft 4, the two connecting rods 33 are located between the two rotating shafts 4, and the axial direction of the rotating shaft 4 is parallel to the width direction of the connecting seat 31. The pressing block 42 for pressing the connecting band 15 on the connecting seat 31 is fixedly connected on the two turnover plates 41, the sawtooth 43 is arranged on the pressing block 42, and the sawtooth 43 partially penetrates into the connecting band 15.

[0049] The lock catch 5 for limiting the turnover of the two turnover plates 41 and keeping the pressing block 42 in the state of pressing the connecting band 15 is arranged on the connecting seat 31, the lock catch 5 includes the sliding block 51 slidingly arranged on the turnover plate 41, and the sliding direction of the sliding block 51 is always perpendicular to the axial direction of the rotating shaft 4. The limiting block 52 is fixedly connected between the two connecting rods 33 of the connecting seat 31, and the insertion slot 53 is arranged on both sides of the limiting block 52 along the length direction of the connecting seat 31. The long slot 54 is arranged on the turnover plate 41, and the length direction of the long slot 54 is parallel to the sliding direction of the sliding block 51. The pulling spring 55 is fixedly connected to one end of the long slot 54 of the turnover plate 41, the other end of the pulling spring 55 is fixedly connected to the sliding block 51, and the pulling spring 55 is used for pulling the sliding block 51 to be inserted into the insertion slot 53. The two inclined surfaces 56 are arranged on the side of the limiting block 52 away from the connecting seat 31, the two inclined surfaces 56 are symmetrically arranged on the limiting block 52 along the length direction of the connecting seat 31, and the sides of the two inclined surfaces 56 away from the connecting seat 31 are oppositely inclined, and the inclined surfaces 56 are used for guiding the sliding block 51 to be inserted into the insertion slot 53.

[0050] One of the turnover plates 41 is fixedly connected with a first limiting plate 6 on the side away from the rotating shaft 4, and the other turnover plate 41 is fixedly connected with a second limiting plate 61 on the side away from the corresponding rotating shaft 4. When the two turnover plates 41 are flipped towards each other to abut on the connecting seat 31, the pressing block 42 is pressed on the corresponding connecting belt 15, and the first limiting plate 6 and the second limiting plate 61 overlap each other along the thickness direction of the connecting seat 31. The first limiting plate 6 and the second limiting plate 61 are both provided with a limiting groove 62, and the groove wall away from the limiting block 52 is open. When the first limiting plate 6 and the second limiting plate 61 overlap each other, the limiting groove 62 of the first limiting plate 6 and the limiting groove 62 of the second limiting plate 61 are aligned and overlapped with each other. The connecting seat 31 is fixedly connected with a support seat 63 for supporting the first limiting plate 6 and the second limiting plate 61, and the support seat 63 is hingedly connected with a stud 64 for inserting into the two overlapping limiting grooves 62. The stud 64 is threadedly connected with a limiting nut 65, and the limiting nut 65 presses the first limiting plate 6 and the second limiting plate 61 tightly on the support seat 63.

[0051] Before connecting the two connecting belts 15, the operator first opens the two turnover plates 41 on the connecting seat 31, inserts the connecting belt 15 into the accommodating groove 32 from the gap between the turnover plate 41 and the connecting seat 31, and then inserts the connecting belt 15 into the limiting hole 34. Then the operator passes the connecting belt 15 around the connecting rod 33, and finally passes out from the gap between the turnover plate 41 and the connecting seat 31, thus completing the installation of the connecting belt 15.

[0052] The operator rotates the turnover plate 41 to press the pressing block 42 on the turnover plate 41 tightly on the corresponding connecting belt 15. During the flipping of the turnover plate 41, the sliding block 51 first abuts against the corresponding inclined surface 56, and the operator presses the turnover plate 41. The inclined surface 56 pushes the sliding block 51 to move away from the limiting block 52 against the elastic force of the tension spring 55. When the turnover plate 41 is flipped to align with the corresponding insertion slot 53, the sliding block 51 is reset and inserted into the insertion slot 53 under the elastic force of the tension spring 55. At this time, the turnover plate 41 abuts on the connecting seat 31, and the pressing block 42 is pressed tightly on the corresponding connecting belt 15. Under the limiting action of the insertion slot 53 on the sliding block 51, the turnover plate 41 is prevented from being flipped in the opposite direction, so that the pressing block 42 remains pressed on the connecting belt 15.

[0053] The operator connects and tightens the two connecting belts 15 by the above-mentioned method, and finally the operator flips the stud 64 to insert the stud 64 into the limiting groove 62 of the first limiting plate 6 and the second limiting plate 61, and threadedly connects the limiting nut 65 on the stud 64, so that the limiting nut 65 is pressed tightly on the first limiting plate 6 and the second limiting plate 61, further fixing the two turnover plates 41, improving the stability of the two connecting belts 15, and further improving the connecting effect between the two water bags 11.

When the clamping blocks 73 are clamped in the clamping grooves 74, the crossbar 7 closes the opening of the hooks 71, and a limiting ring for connecting with the connecting ears 25 is formed between the hooks 71 and the crossbar 7. The two ends of the crossbar 7 are fixedly connected with lock nuts 75, the opposite ends of the two lock nuts 75 are fixedly connected with sleeves 76, the sleeves 76 are sleeved on the crossbar 7, and the sleeves 76 are used to limit the clamping blocks 73 from being separated from the corresponding clamping grooves 74.

[0055] The lower end of the pull rope 23 is fixedly connected with a basket bolt 77, and two connecting ropes 78 are fixedly connected to the basket bolt 77, the connecting ropes 78 correspond to the ends of the crossbar 7 one by one, and the lower ends of the two pull ropes 23 are fixedly connected with the corresponding ends of the crossbar 7.
