Special fixing tool for micrometer gauge block

The utility model provides a special fixing tool for a micrometer gauge block. The objective of the utility model is to solve the contradiction among measurement accuracy, reliability and high efficiency in a micrometer metrological verification process. The device specifically comprises a plurality of step platforms which are connected in sequence, square holes with different widths are formed inthe step platforms, the square holes are used for containing gauge blocks with different center lengths, the size of the square holes is slightly larger than that of the gauge blocks to be contained,and the hole depth of the square holes is slightly smaller than 1/2 height of the gauge blocks to be contained. The micrometer has the advantages that on one hand, the ergonomic requirement is met, indication errors of a plurality of measured points of the micrometer can be conveniently and rapidly measured, and the working efficiency is greatly improved; on the other hand, an operator does not need to hold the gauge bloc
