When handling workpieces on the lower rack, operators are restricted by the fixed state of the upper rack and are easily bumped, posing a safety hazard. Furthermore, because the workpieces placed on the racks are heavy, when they need to be docked on a non-flat surface, even a slight slope can easily cause the racks to slip, causing damage to the workpieces or equipment. Summary of the Invention

[0003] In order to solve the deficiencies in the prior art, the utility model provides a two-layer material rack, which has the advantages of being flippable, stable and having high working efficiency.
