  • Patent number: 11972962
    Abstract: The disclosure provides an adjustable device including plates and at least two adjustable modules connect with two adjacent of the plates. The adjustable module can stretch or shrink to change a distance between plates. The disclosure also provides an adjustable storage box including an upper cover and a lower cover. A storage space is formed by the upper cover and the lower cover and for the accommodating of the adjustable device. When the upper cover moves upward relative to the lower cover, the adjustable modules changes from a compression state to a stretch state and increase a distance between plates. Whereby, it is easy to pick and place object when a distance of two adjacent plates increases. The overall volume of the adjustable device is reduced when a distance of two adjacent plates decrease, thereby saving the working space.
