Abstract
The utility model discloses a mechanical underground diameter-detecting probe. Spring pressure which is detected by a pressure sensor is used for calculating the size of the inner diameter of a pipe well. The mechanical underground diameter-detecting probe has the advantages of being simple in structure, simple and easy to operate, convenient to maintain, sensitive in analyzing, accurate in measuring and the like. The defect that a traditional mechanical caliper is not high in analyzing sensitivity due to the fact that a sliding potentiometer is used for detecting indirectly is avoided.
