The length of the measuring rod 323 can be adjusted according to practical conditions, so as to meet the measuring requirements under the condition of different lengths. The length accuracy of the rod piece measured in this way can reach the minimum index value of the dial indicator, which is 0.01mm in the utility model, so that the measurement accuracy of the rod piece 50 can reach 0.01mm.
