The invention provides a fine tuning jig for an etching sheet, which enables the etching sheet to be finely tuned in front, back, left and right positions and ensures the dimensional accuracy of a punched product. An inner groove is formed in the center of the surface of the lower portion of the hardware die holder. The etching sheet comprises an etching sheet body and a lower convex cutting die; and a plurality of slide blocks. Etching piece positioning holes are formed in the positions, corresponding to the four corners of the etching piece, of the inner groove respectively, positioning holes are formed in the four corners of the etching piece respectively, at least one sliding block is arranged on each of the four edges of the inner groove, and the inner surfaces of the sliding blocks are tightly attached to the outer edge of the etching piece. Fastening screws penetrate through the positioning holes and then are fixedly installed in the etching piece positioning holes respectively, and fixing installation
