[0002] A pallet is a medium that transforms static goods into dynamic goods. It is a cargo platform and an active platform, or a movable ground. Even if the goods lose their flexibility when placed on the ground, they immediately become active and become flexible mobile goods once they are loaded on the pallet. This is because the goods on the pallet are always ready to move. This dynamic loading and unloading method with pallets as the basic tool is called pallet operation.

[0003] An adjustable pallet truck with publication number CN220483883U has the following defects during use:

[0004] The utility model has a locking nut threadedly connected to the locking screw, and the locking nut is squeezed on the outer wall of the fixed frame, which is convenient for better adjustment of the fixed frame and the movable plate, so that the fixed frame and the positioning plate can stack more goods that need to be transferred. In actual use, depending on the shape and size of the goods, a forklift may be required to insert the pallet from a certain fixed direction for transportation. The pallet cannot be adjusted according to actual conditions, resulting in inconvenience during transportation. For this reason, we propose an adjustable pallet truck. Utility Model Content
