[0002] In the product specification measurement of high-requirement product dimensions, it is often necessary to measure the side holes, inner holes, thread concentricity, and thread position distance of the parts. Using different gauges to measure different elements requires measuring a large number of products, which will increase the overall operation time. In addition, when using different gauges, the operator needs to switch and adjust the tools in multiple steps, which increases the complexity and technical requirements of the operation. There is a risk of readjustment and recalibration every time the gauge is replaced, which may lead to discontinuity and increased errors in the measurement results, and may also cause data to be out of sync or difficult to quickly compare.

[0003] Generally, there are many measurement dimensions involved in specific products, and many places that need to be measured are difficult to test directly. At the same time, the measurement requires symmetrical dissection and the use of relevant precision instruments such as projectors, which results in high measurement costs.

[0004] Therefore, it is necessary to simplify the measurement method by making a gauge and quickly determine whether the product meets the requirements. This application proposes a simple measurement tool with high requirements on product dimensions to solve the problems raised in the above background technology. Utility Model Content
