Tool for measuring size of blind hole

The utility model discloses a tool for measuring the size of a blind hole. The tool comprises at least one measuring table and a measuring rod, the measuring table is in a circular truncated cone shape, and a first scale mark representing the diameter and a second scale mark representing the height are marked on the circumferential face of the measuring table. A through hole vertically penetrating from the top face to the bottom face is formed in the measuring table, the size and the shape of the cross section of the measuring rod are matched with the size and the shape of the through hole so that the measuring rod can move in the through hole, the height of the measuring rod is larger than that of the measuring table, and third scale marks representing the height are marked on the measuring rod. The tool is simple in structure, convenient to operate, low in requirement for operators and small in measurement error. 本实用新型公开了一种测量盲孔尺寸的工具，包括至少一个测量台和测量杆；测量台呈圆台状，测量台的圆周面上标识有代表直径的第一刻度线和代表高度的第二刻度线；测量台上开设有从顶面到底面竖直贯通的通孔
