The nylon fixing feet 2 can effectively support the sheet metal base shell 1 and ensure the overall stability.

[0023] Working principle: By rotating the adjustment knob 401 on the front of the sheet metal base 1, the fine-tuning screw 402 can be rotated. Then, under the limiting action of the limiting sliding hole 101, the fine-tuning protrusion slider 403 can move back and forth, which can drive the screen printing table honeycomb table surface 3 to move back and forth synchronously. Similarly, by rotating the adjustment knob 401 separately set on the side of the sheet metal base 1, the left and right movement of the fine-tuning protrusion slider 403 can drive the screen printing table honeycomb table surface 3 to move left and right synchronously, thereby realizing the effective adjustment of the position of the screen printing table honeycomb table surface 3.

[0024] Furthermore, adjust the position of the clamping front crossbar 804 on the optical axis 803, and then ensure the position of the clamping front crossbar 804 is fixed by rotating the hand-tightening bolt 806. Since both the clamping front crossbar 804 and the clamping rear crossbar 805 include an upper clamping bar and a lower clamping bar set on the lower end surface of the upper clamping bar, they can be effectively used to clamp the wire mesh. The pin holder 6 on the honeycomb table surface 3 of the screen printing table can effectively support the printing substrate. It works through the cylinder body 9 and under the limiting action of the limiting shaft 701 and the right angle connecting seat 11, it can effectively drive the frameless steel screen frame 8 to rotate upward to open or rotate downward to a horizontal state for printing work, saving time and effort.
