[0037] When in use, several placement plates 103 are first stacked and placed at the bottom of the box body 101. When fresh food needs to be placed, the heights of different placement plates 103 are adjusted. When the distance between the placement plates 103 needs to be increased, the placement plates 103 are manually lifted and moved upward so that the trapezoidal slider 203 is stuck in the corresponding groove 201 to achieve a fixing effect. When the placement plates 103 need to be lowered, the pull ring 209 is pulled by hand to drive the reset block 207 to move downward, and then the pull rope 205 is pulled downward, causing the two trapezoidal sliders 203 to retract into the slot 202 along the direction of the slot 202, so that it is easy to adjust to the appropriate height according to the size of the fresh food. The pull ring 209 is loosened, and the reset block 207 drives the pull rope 205 to restore the original horizontal state, and the trapezoidal slider 203 is stuck in the groove 201 to maintain the stability of the fresh-keeping box.
