The internal fixed connection of 2 is a fixed shaft 25, which is used to connect the worm gear 26. The surface of the worm 23 is meshed with the worm gear 26, which is used to drive the connecting threaded rod 27 to move by its own rotation. The surface of the worm gear 26 is threadedly sleeved with the connecting threaded rod 27, which is used to connect the universal wheel 28. The surface of the connecting threaded rod 27 is fixedly connected with the universal wheel 28, which is used for the movement of the storage cart 1. The end of the connecting threaded rod 27 away from the universal wheel 28 is fixedly connected with a connecting plate 29, which is used to limit the movement position and direction of the connecting threaded rod 27. The internal fixed connection of the storage support leg 2 is a guide rod 210, which is used to guide the movement of the connecting threaded rod 27.

[0030] Furthermore, the storage support legs 2 are symmetrically distributed in two sets at both ends of the protective connecting tube 21. The worm gear 23 is connected to the internal rotation of the storage support legs 2 through the storage knob 22. The two sets of storage support legs 2 are connected to the same side of a storage cart 1 through the protective connecting tube 21, thereby storing two sets of universal wheels 28 at one time. Rotating the storage knob 22 drives the worm gear 23 to rotate.

[0031] Furthermore, the worm gears 23 are symmetrically distributed in two sets at both ends of the connecting rod 24. The connecting rod 24 is internally connected to the worm gears 23 and the protective connecting tube 21. The worm gears 23 rotate with the rotation of the storage knob 22, and the connecting rod 24 drives the other set of worm gears 23 to rotate synchronously with the rotation of the worm gears 23.

[0032] Furthermore, the worm gear 26 is rotatably connected to the surface of the worm 23 and the fixed shaft 25, and the connecting threaded rod 27 is movably connected to the surface of the storage support leg 2 via the worm gear 26. The worm gear 26 rotates on the surface of the fixed shaft 25 as the worm 23 rotates, and the connecting threaded rod 27 moves as the worm gear 26 rotates. The worm 23 and the worm gear 26 are self-locking structures and will not rotate without external force.

[0033] Furthermore, the caster wheel 28 is movably connected to the surface of the storage support leg 2 via the connecting threaded rod 27. The guide rods 210 are symmetrically distributed in two sets on the surface of the connecting plate 29. The connecting plate 29 is movably connected to the surface of the connecting threaded rod 27 and the guide rods 210. The caster wheel 28 is retracted into the storage support leg 2 as the connecting threaded rod 27 moves. The connecting plate 29 moves on the surface of the guide rods 210 as the connecting threaded rod 27 moves, thereby providing guidance for the movement of the connecting threaded rod 27.
