In the prior art, publication number CN216400886U discloses a high-definition silk-screening device for mobile phone cover glass. In this scheme, a bidirectional screw is rotated by a metal ring, so that two second threaded sleeves drive the right-angle trapezoidal structure of the abutment blocks along the bidirectional screw to move toward each other, so that the inclined surfaces of the two abutment blocks clamp the silk screen plate inserted into the rectangular sleeve, and the rectangular support frame plate welded on the rectangular sleeve can support the silk screen plate, increase the stability and horizontality of the silk screen plate on the rectangular sleeve, and has the advantage of convenient installation and disassembly of the silk screen plate, which is beneficial to the later disassembly and cleaning of the silk screen plate.

[0003] However, since the clamping mechanism in the above scheme mainly clamps the screen plate through the abutment blocks, so that the two sides of the screen plate are fixed, in actual use, since the printed pattern part of the screen plate often has a certain elasticity, the screen plate is prone to local deformation during the movement of the scraper, which may cause the screen plate to shift as a whole, making it difficult for the abutment blocks that are not in complete contact with the screen plate frame to meet the clamping requirements of the screen plate, resulting in an adverse effect on the final printing effect of the glass cover.
