Flexible inclinometer device with initial deviation angle deviation correction function

The utility model belongs to the technical field of flexible inclinometers, and particularly relates to a flexible inclinometer device with an initial deviation angle deviation correction function, which comprises an upper-section inclinometer component and a lower-section inclinometer component which are arranged in an inclinometer pipe, and further comprises a connecting component arranged between the upper-section inclinometer component and the lower-section inclinometer component, the upper-section inclinometer assembly and the lower-section inclinometer assembly are the same in structure and size, a hollow plug at the top end of the connecting assembly is inserted into a bottom opening of a steel pipe of the upper-section inclinometer assembly, and then the hollow plug is screwed to an external thread at the lower end of the steel pipe of the upper-section inclinometer assembly through a locking nut for limiting. Then the hollow plug at the bottom end of the connecting assembly is inserted into the top o
