[0025] In some embodiments (not shown in the drawings), the connection between the sliding block 35 and the lead screw 36 can be changed to a quick-change tweezers, allowing the user to quickly change the height of the partition without turning the adjustment knob 37; or a transparent window can be installed on the top or side of the storage box 31 to check the status of the stored items in real time; furthermore, replaceable damping washers can be added between the upper partition 39 and the lower partition 312 to reduce the effects of external vibrations on the stored items.

[0026] The working principle of the present utility model: The modular mobile storage unit allows a high degree of free expansion through the modular connection unit 2, whose mutual locking structure of the lower butt section 23 and upper fitting structure 22 greatly simplifies the assembly process and reduces manufacturing costs, thus promoting large-scale application; the user only needs to insert the butt section 23 into the upper fitting structure 22 to perform unit stacking, which is extremely easy to operate.At the same time, removable upper and lower partitions 39, 312 are configured in the storage unit 3, which form an adjustable partition system by connecting the mounting hole 310 and the locking block 313, which can both divide the storage area for multiple species and remove the partitions to restore the overall space and greatly improve the functional adaptability of the device.

[0027] From the above description, it can be seen that the above-mentioned embodiments of the present utility model have achieved the following technical effects: This modular mobile storage unit allows a high degree of free expansion through the modular connection unit, whose mutual locking structure of the lower butt portion and upper fitting structure greatly simplifies the assembly process and reduces the manufacturing cost, thus promoting large-scale application; the user only needs to insert the butt portion into the upper fitting structure to perform unit stacking, which is extremely easy to operate.At the same time, removable upper and lower partitions are configured in the storage unit, which form an adjustable partition system through the plug-in connection and adjustment of mounting hole and locking block, which can both divide the storage area for multiple species, and remove the partitions to restore the overall space and greatly improve the functional adaptability of the device.

[0028] It should be understood that in the description of the present utility model, orientation terms such as "front, back, top, bottom, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" simply refer to the orientations or positions shown in the drawings to facilitate the description of the utility model, and in the absence of a contrary statement, these orientation terms do not indicate or imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation, so this cannot be understood as limiting the scope of protection of the present utility model; the terms "inside, outside" refer to the inside and outside of the outline of the respective parts.

[0029] For descriptive purposes, relative spatial terms such as "above...", "above of...", "superficial of...", etc. may be used herein to describe the spatial relationship between a device or feature depicted in the image and other devices or features. It should be understood that the spatially relative terms are intended to exclude various orientations in use or operation that differ from the position depicted in the image. For example, if the device depicted in the drawings is turned over, an element described as being "above another device or structure" or "over another device or structure" would then be positioned as being "below or under another structure" or "under another device or structure." Therefore, the exemplary term "above..." can encompass both "over..." and "under..." as two positions.

[0030] The device can also be positioned in other different ways (e.g. rotated 90 degrees or in other positions), and the relative description of the space used here will be explained accordingly.

[0031] Furthermore, it should be noted that the use of the terms "first," "second," etc., to define components is solely for the purpose of distinguishing the respective components.
