Description

Technical Field

[0001] The invention relates to the technical field of dimension measurement, and in particular to a dimension measuring instrument that is convenient for recording. Background Art

[0002] Dimension measuring instruments are usually used to refer to equipment used to measure the size, dimensions or dimensions of an object. They are widely used in manufacturing, construction, healthcare, scientific research and other fields. Especially in the product design process, they are almost indispensable. Common dimension measuring instruments include tape measures, micrometers and vernier calipers, etc. In the actual use of current dimension measuring instruments, for example, during the measurement process of the micrometer, after the clamping work is completed, the micrometer needs to be put down during the recording process. Although it has been clamped stably, during the placement process, it is inevitable that the product will come into contact with the desktop, causing certain vibrations and causing measurement errors, which need to be optimized and improved.
