The invention provides a stamp module with a stamp surface anti-theft mechanism, which includes a seat body, a holding mechanism and a trigger mechanism. The lower end of the seat body is provided with a stamp body; a sliding plug cavity is formed in the seat body, and the sliding plug cavity is vertically slidingly fitted. There is a pressing block, a liquid sac placement cavity for placing the liquid sac is formed between the pressing block and the ground of the sliding plug cavity, and the bottom surface of the liquid sac placement cavity is communicated with the capillary pipeline arranged on the printing surface of the stamp body through the pipeline; the holding mechanism, It is connected with the pressing block to keep the pressing block at the upper limit position; the trigger mechanism is connected with the holding mechanism and is used for triggering the pressing block to move downward, so that the pressing block squeezes and breaks the liquid sac, so that the The dye in the sac flows through the capillary to the print surface. The seal module with the seal surface anti-theft mechanism of the present invention, by arranging a liquid bag inside, when the seal is stolen, the liquid bag is remotely opened and the liquid bag is broken through the mechanism, so that the internal non-red dye flows to the seal surface, so that it cannot be stored in the seal. Finished stamping.
