Improvement Design and Application of Micrometer

Micrometer is a length measuring tool,and can precisely measure general length.As part of complexity of structure,there are a lot of parts size are not directly measured,such as slot width,the contoured surface size etc..I design three micrometer can accurate measurement of these dimensions.The design mainly to dial indicator and micrometer reasonable together.Improved design of heterogeneous size micrometer measurement has a certain reference value
