[0002] As people's living standards improve, the efficiency of production and processing is gradually increasing. In the process of production and processing, the requirements for product quality are getting higher and higher. Therefore, it is necessary to measure and inspect the products to ensure that the product quality meets the standards. The measuring fixture should have the characteristics of high measurement accuracy and small error to improve work efficiency.

[0003] However, the existing measuring jigs are inconvenient to adjust the limited position, to limit objects of different shapes, to measure in all directions, and the back and forth limited adjustment reduces the measurement efficiency. For example, the Chinese utility model patent with the authorization announcement number CN 209706698U discloses a special measuring jig, which includes a base. Through the matching setting between the movable block, the fixed shaft and the compression spring, the measuring block can be squeezed at one end of the workpiece, which is convenient for the measuring block to fit the workpiece. On the one hand, it ensures the accuracy of the measurement, and on the other hand, it avoids having to press the measuring block with the hand to measure, which is more labor-saving. However, it is inconvenient to adjust the limited angle, and only the thickness can be measured during measurement. It is inconvenient to measure in all directions, and the position needs to be readjusted, which reduces the measurement efficiency. Therefore, we propose a fine-tuning measuring jig that is convenient to limit, so as to solve the above problems. Utility Model Content
