Lifting type goods shelf

According to the lifting type goods shelf, the number of the lifting plates is the same as that of the lead screws, the connecting blocks used for being in threaded connection with the lead screws are arranged on the lifting plates, the lifting plates are connected with the corresponding lead screws through the connecting blocks respectively, and the lifting plates divide the inner space of the goods shelf box into a plurality of storage cavities; key grooves in second bevel gears are connected with flat keys, so that the second bevel gears are meshed with the corresponding first bevel gears one by one, a transmission shaft is driven by a motor to rotate, the transmission shaft transmits mechanical torque to the second bevel gears through the flat keys, the first bevel gears are driven by the second bevel gears to rotate, and therefore the lifting plate is controlled to ascend and descend at the same time. When one lifting plate needs to be independently controlled to ascend and descend, only the second bevel
