Problems solved by technology

[0003] At present, more than 95% of the tests are installed vertically in a cylindrical shape. Although the general shape of the samples is the same, the height of most samples, the diameter of the flange and the bottom installation form are very different.
The existing sample fixture can basically only be designed according to a single sample, and basically can only meet the installation requirements of a single sample, because although the sample fixture can meet the installation requirements of the test, if each sample must be The cost, time cost and other costs required by the fixture are relatively high
