The strip-shaped carrying strap includes a first end, a second end, and a carrying strap body. The container sleeving assembly includes two sleeve ropes and an adjusting element, where each sleeve rope includes a first rope end, a second rope end, and a rope body, the first rope end of each sleeve rope is connected to the first end, the second rope end of each sleeve rope is connected to the second end, and the adjusting element is assembled on the two rope bodies of the two sleeve ropes, so that the adjusting element, the two rope bodies, and the first end of the strip-shaped carrying strap encircle a container sleeving hole. The adjusting element can slide relatively along the two rope bodies so as to adjust the size of the container sleeving hole.
