point of the mounting column 2 through the second measuring block 46 to the central point of the mounting column 2 minus the reading displayed on the reading 46 That is, the inner diameter of the workpiece 3 can be obtained, for the outer diameter, if the second measuring block 46 on the table 1 moves in an extending manner relative to the first measuring block 45, the outer diameter of the workpiece 3 can be obtained by subtracting the reading displayed on the second measuring block 46 from the distance from the zero graduation line of the second measuring block 46 on the table 1 to the central point of the mounting post 2 in the initial state, if the second measuring block 46 on the table 1 moves in a contracting manner relative to the first measuring block 45, the inner diameter of the workpiece 3 can be obtained by adding the reading displayed on the second measuring block 46 to the distance from the zero graduation line of the second measuring block 46 to the central point of the mounting post 2, and when it is known that the standard inner and outer diameters of the workpiece 3 need to be detected by measuring whether the actual size of the workpiece 3 is the same as the standard size of the workpiece 3, the standard sizes of the indicating block 410 and the workpiece 3 on the second measuring block 46 can be made to be opposite to each other by moving the slider 49, the size of instruction block 410 is the same with the size of reading block 4110, when instructing block 410 and reading block 4110 coincidence promptly, the actual dimension of work piece 3 is the same with the standard size of work piece 3, measuring work piece 3 is the certified products, do not need the reading promptly, can the snap judgments measuring work piece 3 be the certified products, and the distance between two sets of 41 is big, the magnetism that produces influences for a short time, do not influence 4 normal work, thereby compare and utilize leading rule and no-go
