The utility model relates to the field of clamp detection, and particularly relates to a precision checking tool for an air tightness detection device. The precision checking tool is characterized in that a checking block is provided with a first groove, the plane, where the first groove is reserved, of the checking block is a plane, the depth of the first groove equals to a clearance safety value, and precision checking can be completed through aligning the first groove to a positioning supporting block. The tool replaces a workpiece with the checking block and replaces the clearance of a feeler gauge plugged below the workpiece with the depth of the first groove, thereby being simple and convenient to operate, reducing the artificial operation error at the same time, and ensuring the detection precision.
