[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This utility model provides a technical solution: a foldable bag, including a mother shell 1, a daughter shell 2 disposed on one side of the mother shell 1, and rubber pads or casters that can be installed at the bottom of the mother shell 1 according to actual use. There are two mother shells 1, which are hinged together. The side of the daughter shell 2 is welded and fixed to a support plate 3. The interior of the mother shell 1 slides with the support plate 3, and the mother shell 1 and the support plate 3 support the items. The mother shell 1 has a rectangular groove inside, which allows it to slide against the outer side of the reinforcing plate 4. One end of the reinforcing plate 4 has a threaded hole. The side of the daughter shell 2 is welded to one end of the reinforcing plate 4. The reinforcing plate 4 effectively enhances the overall load-bearing capacity of the mother shell 1 and the daughter shell 2. The threaded rod 5 is rotatably connected to the outer side of the mother shell 1. The reinforcing plate 4 is rotatably connected to the threaded rod 5 through a threaded hole. One end of the threaded rod 5 is welded and fixed to the worm gear 6. An operating box 7 is provided on the side of the mother shell 1. The other end of the threaded rod 5 extends into the operating box 7 and is welded and fixed to the worm gear 6. The inner wall of the operating box 7 is rotatably connected to one end of the worm 8. One end of the worm 8 extends to the outer side of the operating box 7 and is welded and fixed to the handwheel. The outer side of the worm 8 is simultaneously engaged with two worm gears 6. The rotation of the threaded rod 5 causes the reinforcing plate 4 to move inside the mother shell 1. The distance between the mother shell 1 and the daughter shell 2, as well as the internal storage space, are adjusted by the reinforcing plate 4. The side of the operating box 7 is rotatably connected to the outer side of the threaded rod 5 via a bearing sleeve. The length of the operating box 7 is adapted to the height of the mother housing 1, ensuring that when one side of the operating box 7 rotates with the hinge and the two mother housings 1 are stacked, the operating box 7 will move with the rotation of the mother housing 1, avoiding interference with the movement of the mother housing 1. At the same time, the operating box 7 can be used to simultaneously rotate the threaded rods 5 on both sides and simultaneously adjust the accommodating space of the mother housings 1 on both sides, reducing the adjustment time required by the user and ensuring that the accommodating space of the mother housings 1 on both sides is synchronized, so that they remain consistent when stacked. The top surface of the mother shell 1 is hinged to the cover plate 9 via an ear plate. A sliding groove is provided inside the cover plate 9, which slides in conjunction with the telescopic plate 10. A retaining groove 11 is provided on the telescopic plate 10, and a mating groove 12 is provided inside the daughter shell 2. The cover plate 9 and the telescopic plate 10 allow for synchronous adjustment of the distance between the mating mother shell 1 and the daughter shell 2, enhancing the actual usage effect. The clamping plate 13 is an L-shaped plate. The outer side of the clamping plate 13 is movably engaged with the clamping groove 11. One end of the push plate 14 passes through the side of the sub-housing 2 and is welded and fixed to the clamping plate 13. When installing the telescopic plate 10, the clamping plate 13 is passed through the clamping groove 11. The spring force of the spring 15 pushes the clamping plate 13 to move inside the clamping groove 11 until the top of the clamping plate 13 engages with the clamping groove 11, thus fixing the telescopic plate 10 to the sub-housing 2. The side of the clamping plate 13 is welded and fixed to the push plate 14. The push plate 14 and the spring 15 are distributed on both sides of the clamping plate 13. The spring 15 is installed inside the mating groove 12. Working principle: During use, turning the handwheel causes the worm gear 8 to rotate, which in turn rotates the worm wheels 6 and threaded rod 5 on both sides. The rotation of the threaded rod 5 causes the reinforcing plate 4 to move inside the main housing 1. The reinforcing plate 4 adjusts the distance between the main housing 1 and the secondary housing 2, as well as the internal storage space. Then, the items to be stored are placed inside the main housing 1 and the support plate 3. The worm gear 8 allows the main housing 1 and the secondary housing 2 on both sides to be adjusted synchronously, saving the user time in adjusting the internal space of the main housing 1. When the main housing 1 and the secondary housing 2 move to adjust the storage space, the telescopic plate 10 will extend and retract synchronously inside the cover plate 9. When it is necessary to remove the items inside the main housing 1, push the push plate 14 to move the locking plate 13 inside the mating groove 12 until the top of the mating groove 12 moves into the locking slot 11. Then, the telescopic plate 10 can be lifted upwards to disassemble the cover plate 9 and the telescopic plate 10. Similarly, the cover plate 9 and the telescopic plate 10 can be used to close the main housing 1, enhancing the actual use effect.
