摘要： An inside micrometer including an inside micrometer body (1) with a first spindle (11) screwed in an advanceable and retractable manner in an axial direction, to which anvil (30) having different length in increments of a predetermined dimension and an extending collar (40) interposed between the anvil (30) and the inside micrometer body (1) are selectively attached to adjust the measurement range, has an extending rod (50) selectively attached to the inside micrometer body (1) in an attachable and detachable manner and having a second spindle 58 which is advanced and retracted together with the first spindle (11), so that the length of the second spindle (58) is added to the measurement range extended from one of the anvils (30) as well as the length of the extending collar (40), thereby reducing the number of the anvils (30).
