The top of the outer periphery of the rollers 61 is higher than the top of the carrier plate 3. When the refrigeration device 100 is pushed on the carrier plate 3, the rollers 61 convert the friction between the refrigeration device 100 and the carrier plate 3 from sliding friction to rolling friction, reducing friction and making pushing the refrigeration device 100 more labor-efficient.

[0023] Furthermore, as shown in the figure, the clamping mechanism of this embodiment includes two second vertical plates 70, which are fixedly mounted on the left and right sides of the support plate 3 in sequence.
