The invention provides a clamping tool for a blade and a check measuring tool for measuring the clamping tool. The method has simple operation, reliable data and good commonality; only one check measuring tool is necessary for the blade of the same model. The invention is characterized in that the clamping tool comprises a mandril blade root and a mandril core, the mandril blade root has the same size and shape as the simulated blade root, the mandril core has a shape of cylinder and is connected with the mandril blade root, the position of the core center line on the mandril blade root is the same as the position of the simulated blade surface center line on the blade root.
