INSIDE MEASURING TAPE MEASURE

摘要

The present invention relates to a tape measure, and more specifically, one side scale of the tape measure is marked with a general scale starting from "0", and the scale is marked together to reflect the length of the tape measure body. Since the inner diameter gap between the objects can be easily measured, the present invention relates to an inner diameter measuring tape which enables to measure the outer diameter and the inner diameter freely under any circumstances.;Features of the present invention as such a tape measure body to be wound inside the tape measure unit; Tape measure unit wound or drawn inside the tape measure body and the scale is marked on the surface; In the tape measure consisting of a measuring hook fastened to the end of the tape measure, the tape measure measure is the outer diameter measuring unit marked with the basic unit scale starting from "0" unit on one side and the starting scale of the tape measure body on the other side Characterized in that the inner diameter measuring unit is marked with the inner diameter measuring unit scale starting from the scale unit added to the length.;Tape measure, outer diameter, inner diameter, circular measurement, graduation
