[0064] The use process of the present invention is as follows: when it is necessary to calculate the similarity of a data document, the user can upload and import the data document for which similarity calculation is required through the document upload and import module 8.

In this way, the system has a review function. When there is a dispute over the calculation result, the calculation record can be reviewed and retrieved, which has a basis, thereby improving the credibility and reliability of the system;

[0068] When the similarity display module 7 needs to adjust the inclination angle of the display screen 22 during use, the push block 35 is pushed upward, so that the moving rod 34 can be moved upward, so that the moving rod 34 can be moved out of the groove, and then the knob 32 is rotated, so that the second shaft 29 can be rotated, and the rotation of the second shaft 29 drives the chain 31 to rotate, and the rotation of the chain 31 drives the rotation of the first shaft 25 to rotate, and the rotation of the first shaft 25 drives the substrate 24 to rotate, and the rotation of the substrate 24 can rotate the display screen 22, so that the inclination angle of the display screen 22 can be adjusted. In this way, the inclination angle of the display screen 22 can be adjusted according to needs during use. After adjustment, the push block 35 is pushed downward to make the moving rod 34 stuck in a groove on the second shaft 29, so that the second shaft 29 can be restricted so that it cannot rotate, so as to avoid the change of the inclination angle of the display screen 22.
