The outer wall of the fixed rod 12 is fixedly connected to the connecting rod 11. One end of the connecting rod 11 is fixedly connected to a nut sleeve 14. A threaded groove 13 is provided on one side of the inner part of the connecting rod 11. The inner part of the main bag 1 is fixedly connected to an inner bag 15. The positioning assembly 7 includes a spring 701, which is fixedly connected to the inner wall of the sliding column 6. One end of the spring 701 is fixedly connected to a sliding plate 702. The sliding plate 702 is slidably connected to the inner wall of the sliding column 6. A block 703 is fixedly connected to the upper surface of the sliding plate 702. The block 703 penetrates and is slidably connected to the inside of the slide plate 4.

[0025] Specifically, firstly, by holding the connecting rod 11, a force is applied to enable the connecting rod 2 10 to rotate smoothly on the outer wall of the sliding column 6; this rotation further pulls the connecting rod 1 9 through an ingenious mechanical linkage system, thereby assisting in pushing the sliding column 6 to slide inside the slide plate 4; this process not only ensures the stability of the device, but also improves the smoothness of operation; as the sliding column 6 moves inside the slide plate 4, the block 703 begins to engage with the inner wall of the positioning hole 5 inside the slide plate 4; this key step ensures that the block 703 can be firmly embedded in the inner wall of the positioning hole 5 through precise mechanical design; at the same time, the reaction force of the spring 701 further pushes the block 703, causing it to stably stagnate on the inner wall of the positioning hole 5 , thereby successfully achieving the fixation of the height of the main bag 1; when the slide plate 4 moves, it will drive the telescopic rod 3 to perform telescopic movement. This movement, through ingenious mechanical design, plays a role in limiting the slide plate 4, ensuring that the device can move within a preset range during operation, thereby avoiding the instability or damage of the device caused by exceeding the limit; the movement of the block 703 brings flexibility in height adjustment to the device; by adjusting the position of the block 703, the device can be adjusted accordingly according to the height requirements of different objects, thereby achieving flexible control of the height; whether in use or when storage is needed, only need to gently press the block 703 to easily achieve adjustment and fixation, making the whole process more convenient and efficient.

[0026] Reference Figure 1 , Figure 4 and Figure 5 A feeding port 16 is provided on the lower side of the main bag 1, and a connecting cover 17 is rotatably connected to the inner wall of the main bag 1; a feeding port 18 is provided on the connecting cover 17, and the feeding port 18 is symmetrically arranged with the feeding port 16; a lower sealing cover is slidably connected to the inside of the feeding port 16, and an upper sealing cover is slidably connected to the inside of the feeding port 18; zipper teeth 19 are fixedly connected to the outer walls of the main bag 1 and the connecting cover 17, and a zipper head 20 is slidably connected to the outer wall of the zipper teeth 19; a plurality of positioning posts 22 are fixedly connected to one side of the outer wall of the connecting cover 17, and a plurality of positioning sleeves 21 are fixedly connected to the outer wall of the main bag 1; the positioning sleeves 21 are slidably connected to the outer wall of the positioning posts 22, and the positioning sleeves 21 and the positioning posts 22 are linearly and equidistantly distributed;

[0027] Specifically, first, manually pull the positioning sleeve 21 to separate it from the outer wall of the positioning column 22; the looseness between the positioning sleeve 21 and the positioning column 22 ensures that the device has flexible operability when in use; next, pull the zipper head 20 to make it slide smoothly along the outer wall of the zipper teeth 19; this design not only ensures the smoothness of operation, but also greatly improves work efficiency; the smooth sliding of the zipper head 20 allows the connecting cover 17 to be quickly opened, thereby forming a larger discharge entrance; the design of this discharge entrance is particularly suitable for loading large objects, making the loading process more efficient and convenient; after the connecting cover 17 is opened, a spacious entrance is formed, which greatly facilitates the rapid loading of large objects; this entrance design not only takes into account the convenience of use, but also improves the overall operating efficiency, so that when loading large objects, it can be quickly The operation can be completed quickly and without obstacles; in addition, the inner bag 15 inside the container bag is made of high-quality wear-resistant material, which has excellent wear resistance and durability, and can effectively extend the service life of the container bag; in the case of frequent use and multiple loading of large objects, the wear resistance of the inner bag 15 is particularly important, which can greatly reduce the wear and damage of the container bag and improve the overall service life and durability; when multiple container bags need to be placed neatly, the connection between the nut sleeve 14 and the thread groove 13 can achieve a stable and smooth effect; the precise combination of the nut sleeve 14 and the thread groove 13 not only ensures the stable placement of the container bag, but also greatly improves the overall safety and reliability; this design enables multiple container bags to remain neat and stable when placed, avoids tipping or sliding due to instability, and ensures the safety and convenience of storage and use.

[0028] Working principle: when in use, by holding the connecting rod 11, the connecting rod 2 10 is rotated on the outer wall of the sliding column 6, and then the connecting rod 1 9 is pulled to assist in pushing the sliding column 6 to slide inside the sliding groove plate 4. At this time, the sliding column 6 moves, thereby driving the card block 703 to engage with the inner wall of the positioning hole 5 inside the sliding groove plate 4. At this time, the reaction force of the spring 701 pushes the card block 703 to stably stagnate on the inner wall of the positioning hole 5, thereby achieving the effect of fixing the height of the main bag 1. At this time, the sliding groove plate 4 moves, thereby driving the telescopic rod 3 to extend and retract, thereby achieving the effect of limiting the sliding groove plate 4. The movement of the card block 703 can achieve the effect of adjusting according to the height of the object. When adjusting or storing, the card block 703 is pressed to achieve the effect of easy adjustment.

[0029] Secondly, when it is necessary to load block objects, the multiple positioning sleeves 21 are disengaged from the outer wall of the positioning column 22, and the zipper head 20 is pulled to slide on the outer wall of the zipper teeth 19, so as to achieve the effect of quickly opening the connecting cover 17. By opening the connecting cover 17, the effect of opening a larger discharge entrance is achieved. The inner bag 15 made of wear-resistant material increases the service life of the container bag. At the same time, when multiple container bags are placed, they are connected to the thread groove 13 through the nut sleeve 14, thereby achieving a stable and smooth effect.
