[0020] See also Figure 1-Figure 4 A portable space-saving kraft paper bag comprises a bag body 1, a handle 2 is installed on the outer wall of the bag body 1, a carrying belt 3 is installed on the inner wall of the bag body 1, a No. 1 rotating plate 4 is installed at the bottom of the inner cavity of the bag body 1, a limiting column 6 is installed in the inner cavity of the No. 1 rotating plate 4, a No. 2 rotating plate 7 is rotatably connected to the inner cavity of the No. 1 rotating plate 4, and a pull wire 8 is fixedly installed on the outer wall of the No. 2 rotating plate 7.
[0021] By installing the handles 2 on both sides of the outer wall of the bag body 1, when the bag body 1 is normally used to load items, the bag body 1 can be lifted as a whole by pulling the handles 2, thereby making the bag body 1 more convenient to use and better for loading and carrying items.
[0022] In a preferred embodiment, there are two handles 2 , and the two handles 2 are respectively installed on both sides of the outer wall of the bag body 1 .
[0023] By installing two handles 2 on both sides of the outer wall of the bag body 1, the bag body 1 can be lifted as a whole under the action of the handles 2 on both sides, so that the bag body 1 can be lifted better, and then the bag body 1 can be carried, thereby achieving the purpose of loading items.
[0024] In a preferred embodiment, two ends of the outer wall of the carrying belt 3 are respectively connected to the inner walls of the bag body 1 on both sides, and the carrying belt 3 is woven from nylon fibers.
[0025] By setting a carrying belt 3 in the inner cavity of the bag body 1, the inner cavity of the bag body 1 is layered under the action of the carrying belt 3. When loading items, the items that cannot withstand pressure are placed on the outer wall of the carrying belt 3, and the items can be carried and lifted under the action of the carrying belt 3.
[0026] In a preferred embodiment: the thickness of the outer wall of the second rotating plate 7 is equal to the distance between the inner wall of the rotating groove 5, and the first rotating plate 4 and the second rotating plate 7 are both made of ABS plastic.
[0027] By installing a No. 1 rotating plate 4 and a rotating groove 5 at the bottom of the inner cavity of the bag body 1, the No. 1 rotating plate 4 and the rotating groove 5 can be used to carry and lift the items, so that the weight of the items can be evenly distributed to the bottom of the bag body 1 under the action of the No. 1 rotating plate 4 and the rotating groove 5.
