When the protection box is pushed above the support block, the telescopic cylinder contracts and resets. At this time, the protection box squeezes the support block downward to reset, and the protection box is palletized inside the transfer box through the limit of the support block. When palletizing and fixing, the support block is limited by the limiting rod to prevent it from rotating counterclockwise and causing the materials to fall, avoiding the situation that the materials at the bottom bear too much pressure, which is beneficial to improving the safety of palletizing and placing. Moreover, through the limit of the support block, the palletizing is more neatly arranged, which is convenient for storage and management and is beneficial to improving the space utilization rate.

When palletizing, slide the square bar body into the protection box. During the palletizing process, the square bar body is contacted and palletized by multiple protection boxes to prevent scratches on the surface of the square bar body. When transportation and movement are required after palletizing is completed, stack multiple transfer boxes. During the stacking process, align the U-shaped blocks and slide them into the U-shaped grooves to ensure neat and flat stacking, and rotate the buckles to be clamped in the U-shaped grooves, which is beneficial to improving the safety and stability during the palletizing and transportation process.
