In addition, in order to reduce sliding of the plurality of hanging members 12 on the one or more connecting seats 22, in this embodiment, a positioning protrusion 821 is further disposed on the lower bottom surface of each of the one or more waist ring plugs 82 adjacent to the one or more waist rings 81, and a height of each of the one or more waist ring plug 82 at this position is equal to the height of the corresponding one of the holes 1222 for hanging the one or more connecting seats 22. Therefore, when each of the plurality of hanging members 12 is hung on the corresponding one of the one or more connecting seats 22, a distance between each of the holes 1222 for hanging the one or more connecting seats 22 and the lower bottom surface of a corresponding one of the one or more waist ring plugs 82 is less than a height of the positioning protrusion 821 by adjusting a length of a corresponding one of the straps 121 for the hanging ring 122. In this embodiment, the straps 121 for the hanging rings 122 are plastic sheets. In other possible embodiments, the straps 121 for the hanging rings 122 can be made of leather or cloth. In other possible embodiments, the straps 121 for the hanging rings 122 can be elastic straps to enable the hanging rings 122 to abut the one or more waist ring plugs 82.

[0079] In this embodiment, as the aforementioned three positioning protrusions 821 are disposed on each of the one or more waist ring plugs 82, when being assembled, the hanging rings 122 needs to be firstly hung on the one or more waist ring plugs 82 through the holes 1222 for hanging the one or more connecting seats 22, and the one or more waist ring plugs 82 are then buckled to the one or more waist rings 81.

[0080] The aforementioned description is merely preferred embodiments of the present disclosure and the scope of the present disclosure should not be limited thereto. Equivalent variations and modifications fall within the scope of the present disclosure provided that they are made based on the content of the specification and the scope of the present disclosure.
