When the handle is rotated to a vertical position, the thin rope is loosened and the upper end of the pallet naturally flips down under the action of gravity, achieving the installation insurance function of preventing the middle layer board from accidentally falling. After loading and unloading, when the handle is turned to a horizontal position, the thin rope is tightened to retract the pallet. At this time, the middle layer board can be lowered normally. No personnel need to enter the compartment during the entire operation, which greatly improves safety.
