The invention relates to a transportation device, in particular to a safe transportation device of mosaic tiles. The safe transportation device of the mosaic tiles aims to achieve that when transported, the mosaic tiles are not prone to damage. The safe transportation device of the mosaic tiles comprises a second electromagnet, front rolling wheels, a transportation box, first fixed pulleys, second fixed pulleys, first springs, a box cover, a second rotating plate, a first iron block, a first rotating plate, a first electromagnet, sponge mats, layering blocks, a tile containing box, stay wires, rollers, rotating rods and back rolling wheels. A groove is formed in the outer bottom of the transportation box. The second electromagnet is arranged in the groove. The safe transportation device of the mosaic tiles achieves that when the mosaic tiles are transported, protective measures are taken in each transportation step, and especially, more protective measures are taken to prevent damage caused by collision among the mosaic tiles.
