Description

Technical Field

[0001] The utility model belongs to the technical field of detection measuring tools, and particularly relates to a small detection measuring tool. Background Art

[0002] Testing gauges are professional tools used to measure the geometric size, shape, position, angle and other parameters of an object. They are an indispensable quality control tool in the fields of manufacturing, scientific research, inspection, etc. Testing gauges are also divided into many types according to the parameters of the measured object and the type of the measured object. When small objects need to be measured or need to be easy to carry, most people will use corresponding small testing gauges. In the measurement of the outer diameter of a small sphere, a common quick measurement method is to use tools such as vernier calipers for detection. However, it is difficult for a vernier caliper to accurately find the corresponding positions of the centers of the two ends of the sphere when measuring the sphere, which makes it difficult to measure the outer diameter with extremely high accuracy. There are often certain errors, and it is often necessary to use multiple measurements to find the average value to reduce the measurement error. Therefore, its measurement requires certain calculations.

[0003] Secondly, different inspectors have different proficiency in the use of vernier calipers, which leads to different inspection speeds when measuring the sphere, and inspectors with insufficient proficiency often have larger errors after measurement.

[0004] In summary, there are some problems when the outer diameter of a sphere is detected using common measuring tools such as a vernier caliper, so a new structure is proposed to solve the above technical problems. Utility Model Content
