[0033] Specifically, a pull ring 14 is fixed to the bottom end of the drawstring 4. A connecting rod 9 is fixed to the outer wall of the pull ring 14, and a rotating column 10 is rotatably connected to the inner wall. This structure allows the pull ring 14 to move flexibly, thereby realizing the expansion of the paper bag. When the pull ring 14 is pulled, the moving disk 13 will rotate accordingly, and the L-shaped block 11 and the L-shaped block 2 12 cooperate with each other, so that the expansion rod 7 is limited while being unfolded, thereby expanding the paper bag. At the same time, a limiting column 3 is fixed near the edge of the front side of the bag body 1 to prevent the pull rope 4 from excessive sliding and ensure the stability of the paper bag. At the same time, the design of the mounting shaft 8 and the limiting column 3 also ensures the stability and durability of the pull rope 4 during use.

[0034] Please refer to the attached Figure 3 - Attachment Figure 4 The partition device 2 includes a second rotating shaft 205, the bottom end of which is rotatably connected to the inner wall of the bag body 1, a partition plate 204 is fixedly connected to the outer wall of the second rotating shaft 205, a card slot 203 is provided on the inner side of the partition plate 204, a rotating block 206 is rotatably connected to the right side of the partition plate 204, the front and rear sides of the inner wall of the bag body 1 are rotatably connected to the first rotating shaft 202, the inner end of the first rotating shaft 202 is rotatably connected to the rotating card block 201, and the outer wall of the rotating block 206 is rotatably connected to the outer wall of the partition plate 204;

[0035] Specifically, a rotating shaft 202 is provided on the front and rear sides of the inner wall of the bag body 1, and one end is rotatably connected to a rotating block 201. When the partition plate 204 needs to be fixed, the rotating block 201 can be precisely docked with the slot 203 to form a stable support, ensuring that the position of the partition plate 204 is fixed and providing a reliable article separation function. The partition plate 204 is the main part of the partition device 2, and the slot 203 opened on the inner side is uniquely designed, which can effectively fix and separate the articles in the bag and prevent damage due to collision during transportation.

[0036] Please refer to the attached Figure 4 - Attachment Figure 5 The left and right sides of the inner wall of the bag body 1 are fixedly connected with folding cardboards 15, the four corners of the bag body 1 are fixedly connected with reinforcement blocks 18, the outer wall of the mounting shaft 8 is fixedly connected with a handle 17, the outer wall of the handle 17 is fixedly connected with an anti-slip sleeve 16, the middle part of the front side of the bag body 1 is fixedly connected with a nameplate 19, a plurality of connecting rods 9 are fixedly connected at the same horizontal height, the middle part of the rear side of the bag body 1 is fixedly connected with a folding sub-bag 20, and the bottom of the bag body 1 is fixedly connected with a wear-resistant pad 21;

[0037] Specifically, a wear-resistant pad 21 is fixedly connected to the bottom of the bag body 1.

In the middle of the front side of the bag body 1, we set a striking nameplate 19, which is used to facilitate user management and classification and also increases the aesthetics.

[0038] Working principle: When the paper bag needs to be expanded, the drawstring 4 is pulled outward to drive the draw ring 14 to move upward, so that the rotating column 10 and the movable disk 13 connected thereto can rotate, so that the connecting rod 9 moves upward together, driving the movable disk 13 below to rotate, and the rotating rod 6 also rotates together, until the rotating rod 6 is rotated to the horizontal and stopped, so that the expansion rod 7 connected to it is stretched to the front and rear sides, so that the bag body 1 is expanded along the fold 5, and at the same time, the L-shaped block 1 11 and the L-shaped block 2 12 are stuck to each other, so that the movable disk 13 is limited and can no longer rotate, and the drawstring 4 is put on the outer wall of the limiting column 3 to limit it, and the self-expansion is completed;

[0039] When different things need to be put into the paper bag, the rotating block 201 is rotated along the rotating axis 1 202 on the front and rear sides to release the partition plate 204 from the limit, and the partition plate 204 is rotated toward the middle along the rotating axis 205 so that the slots 203 on the partition plates 204 on both sides can fit together, and the rotating blocks 206 on the sides of the two partition plates 204 are rotated so that they limit each other.
