When multiple layers of cleaning trays 1 are provided, the top end of the support column 2 is used to support the cleaning tray 1 above, and the top end of the support column 2 does not need to be relatively fixed with the cleaning tray 1 above, and only needs to contact the support column 2 with the cleaning tray 1 above. The position of the support column 2 is located between the limiting structures 11, avoiding interference with the Dewar part. If multiple layers of cleaning trays 1 are provided, the uppermost cleaning tray 1 does not need to be installed with a support column 2.
