[0006] Preferably, a handle is fixedly connected to the top of the top cover, and a plurality of rollers are symmetrically mounted at the bottom of the refrigerator body.

[0007] Preferably, a plurality of grooves are symmetrically arranged inside the cavity, and the size and position of each groove correspond to the size and position of the fixed plate.
