[0002] The measuring tools in the application fields of metrology and testing include: mechanical metrology, mass metrology, force metrology, hardness metrology, capacity and density metrology, speed and vibration metrology, thermal metrology, temperature metrology, pressure metrology, flow and software. In order to conduct metrological tests on the hardness of some objects, laboratories will use hardness testing equipment to test the hardness of objects. In order to accurately position and fix the objects during testing, auxiliary equipment is generally used to limit the objects, thereby increasing the accuracy of the test results.

[0003] There is an auxiliary device for metrological detection, which improves the accuracy of the detection result by assisting the positioning of the object whose hardness needs to be detected. The device comprises two first moving blocks and a second moving block that can move relative to each other, and the two first moving blocks are respectively hinged with connecting rods at both ends of one side of the opposite side. The ends of the connecting rods located on the two first moving blocks, which are away from the first moving blocks, are respectively hinged with the two ends of one side of the second moving block. When the two moving blocks move relative to each other, the two second moving blocks can be driven to move relative to each other through multiple connecting rods, so that the two first moving blocks and the second moving blocks can respectively clamp the four sides of the object to limit the object. However, since the length of the connecting rod is fixed, it can only clamp objects with a bottom length-to-width ratio of a certain value, so the scope of use of the device is limited.

[0004] Therefore, it is necessary to provide a new auxiliary equipment for measurement and detection to solve the above technical problems. Utility Model Content
