[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] Reference Figure 1-Figure 4 The utility model comprises: a press body 1, a positioning plate base 2, a positioning plate 3 and a character head 4, wherein the positioning plate base 2 is arranged on the press body 1; the positioning plate 3 is arranged on the positioning plate base 2; and the character head 4 is arranged on one end of the positioning plate 3 away from the positioning plate base 2.

[0019] Furthermore, the prefix 4 is composed of an extension portion 5 and a font portion 6; at least one axial through hole 7 is arranged on the positioning plate 3; a radial threaded hole 8 connected to the axial through hole 7 is arranged on the side of the positioning plate 3; a bolt 11 matching with the radial threaded hole 8 is arranged on the radial threaded hole 8; the extension portion 5 is inserted into the axial through hole 7; the screw end face of the bolt 11 is in contact with the extension portion 5.

[0020] Furthermore, a positioning plane 9 is provided on the side of the insertion portion 5 close to the radial threaded hole 8; the positioning plane 9 is cut on the prefix 4 for angle positioning, which reduces the adjustment time of the prefix 4; the fastening of the prefix 4 is changed from line contact to surface contact, which increases the force-bearing area.

[0021] Furthermore, the radial threaded hole 8 consists of a large threaded hole and a small simple hole; the diameter of the large threaded hole is larger than the diameter of the small simple hole; the large threaded hole is provided with an internal and external tooth nut 10 matching it; the internal thread diameter of the internal and external tooth nut 10 is smaller than the diameter of the small simple hole; the external thread of the internal and external tooth nut 10 matches the large threaded hole; the internal thread of the internal and external tooth nut 10 matches the bolt 11; the screw end face of the bolt 11 is in contact with the prefix positioning plane 9.

[0022] Furthermore, it also includes a guide column 12, which cooperates with the small simple hole; one end of the guide column 12 contacts the screw end face of the bolt 11; the other end of the guide column 12 contacts the prefix positioning plane 9; the guide column 12 with a flat end face contacts the prefix 4, which improves the positioning accuracy; the guide column 12 is made of softer steel, and a slight deformation occurs during the tightening process, making the prefix 4 more stable; the guide column 12 is a low-value consumable, and its hardness and strength are lower than the positioning plate 3. It is preferentially worn and damaged during use, thereby extending the service life of the positioning plate 3.
