[0013] Technical effects and advantages of the utility model:

[0014] 1. In the actual operation of the utility model, when personnel need to take out materials from the material grid, the electric push rod is started to retract, which can drive multiple fixed rods to rise. The rise of multiple fixed rods drives the bottom plate to rise in the material grid, thereby lifting the materials and making it convenient for personnel to take them out.

[0015] 2. Furthermore, when the aircraft encounters disturbed airflow and produces turbulence, the vibration sensor detects the vibration signal and transmits the signal to the controller. The controller controls the electric push rod to extend downward, thereby driving multiple bottom plates to descend, so that the extended materials retract into the material grid, avoiding the problem of materials falling due to the turbulence. At the same time, when the electric push rod extends upward, it will drive the connecting plate to descend, and the connecting plate will drive the resistance block to extend downward, so that the resistance block contacts the ground, which plays a role in stopping the dining car body, avoiding the aircraft turbulence, causing the dining car body to move or slip, hit the passengers or cause damage.
