A measuring tool, comprising a support portion and a measuring portion, wherein the measuring portion is movably connected to the support portion, the support portion is configured for supporting the measuring portion, and the measuring portion is configured for successively measuring at least one gap between a base and a workpiece on the base.

2 . The measuring tool of claim 1 , wherein the support portion includes a support rod, the measuring portion includes a plurality of rolling elements having different diameters respectively, the rolling elements are connected to the support rod, and the rolling elements are capable of rolling on the base.

3 . The measuring tool of claim 2 , wherein the rolling elements are circular plates, the center of each circular plate is connected to the support rod.

4 . The measuring tool of claim 2 , wherein the rolling elements are spheres, the center of each sphere is connected to the support rod, and the spheres are capable of rotating about their center in any direction.

5 . The measuring tool of claim 2 , wherein the rolling elements have a cylindrical shape.

6 . The measuring tool of claim 2 , wherein the plurality of rolling elements are arranged along the longitudinal direction of the support rod in a descending or ascending order of their diameters.

7 . The measuring tool of claim 2 , wherein the centers of the plurality of rolling elements are arranged in a line.

8 . The measuring tool of claim 2 , wherein the portions of the plurality of rolling elements to be in contact with the base are arranged on a same plane.

9 . The measuring tool of claim 2 , wherein the diameters of the plurality of rolling elements increase sequentially in a linear manner.
