[0021] Specifically, the ink pad 1 (made of copper) serves as the core of the seal's support and ink storage. Copper possesses excellent hardness and wear resistance, providing long-term stable support for internal components. Its main function is to provide space for the seal body 2. The bottom wall secures the sponge 8 for ink storage, while the limiting groove 9 on the inner side wall works in conjunction with the rubber ring 6 to limit the seal body 2 and prevent it from falling off. The sponge 8 is the medium for storing and releasing ink. It is manufactured using a hot-pressing process, with a volume ratio of 4:1 before and after hot pressing. Precise control of the sponge density ensures a perfect fit to the internal space of the copper ink pad 1 while balancing ink absorption and release, preventing excessive ink seepage or insufficient ink from affecting the clarity of the imprint. Simultaneously, it provides upward support when the seal body 2 is closed, assisting in limiting the seal's position. The seal body 2 (made of copper) is the main executor of the seal. The body is made of copper, which is hard and not easily deformed, ensuring long-term stability. The printing surface positioning groove 11 on the lower surface provides an installation reference for the printing surface 7. The rubber ring positioning groove 10 on the side surface is used to fix the rubber ring 6. The threaded groove 15 on the upper surface is fixed to the handle 3 through threaded connection to realize the transmission of force and facilitate the user's operation of stamping. The printing surface positioning groove 11 is opened on the lower surface of the printing body 2 and its size matches the printing surface 7. It is the installation and positioning structure of the printing surface 7. The double-sided adhesive 12 fixed on the top wall can firmly fix the printing surface 7, preventing the printing surface from shifting or falling off during use and ensuring the accurate position of the pattern when stamping. The double-sided adhesive 12 is the connection medium between the printing surface 7 and the printing body 2. It has strong double-sided adhesion. Compared with traditional glue, it has no glue overflow problem, adheres firmly and facilitates the replacement of the printing surface, further improving the stability of the printing surface.

[0022] The printing surface 7 (a special silicone product) serves as the imprint generation component. The silicone material is soft and elastic, allowing it to closely adhere to the sponge 8 for ink application. The lower surface is engraved with the text or pattern to be printed (such as a company logo). Pressing it leaves a clear and complete imprint on the paper. The rubber ring 6 is the core component for sealing and positioning. It possesses good elasticity and wear resistance. Its inner side is installed within the rubber ring positioning groove 10 of the printing body 2, while its outer side protrudes, cooperating with the positioning groove 9 of the ink pad 1 to achieve positioning. Simultaneously, it fills the gap between the printing body and the ink pad, reducing ink evaporation and the entry of external dust, and preventing wear caused by direct friction between the copper printing body 2 and the ink pad 1. The rubber ring positioning groove 10 is located on the side surface of the printing body 2, and its size is the same as that of the rubber ring. The 6 adapter is used to fix the position of the rubber ring 6, preventing the rubber ring from shifting or falling off due to friction and compression during use, ensuring that it can always accurately fit with the limiting groove 9, and maintaining the stability of the seal body and the ink pad. The threaded groove 15 is located on the upper surface of the seal body 2 and adopts an internal thread design, which matches the external thread of the handle 3. The seal body 2 and the handle 3 are firmly fixed through the threaded connection. Compared with other connection methods, the threaded connection is easy to disassemble and facilitates the maintenance or replacement of the handle. The handle 3 (made of copper) is the user's grip and operation part. The copper material feels heavy and is not slippery, and is suitable for daily grip. It is connected to the seal body 2 through the thread, which can transmit the user's pressing pressure to the seal body 2 to complete the stamping action.

[0023] The handle 4 (plastic) is fixed to the upper end of the handle 3. The plastic material is lightweight and easy to process, reducing the overall weight of the stamp and improving ease of use. The display groove 14 on the upper surface provides installation space for the label sticker 13 and the transparent plastic plate 5, while also serving a protective and decorative function. The display groove 14, located on the upper surface of the handle 4, is the information display area. The bottom wall is used to fix the label sticker 13, and the inner side wall is fixed to the transparent plastic plate 5, providing protective space for the label sticker and ensuring clear information display without damage. The label sticker 13, as an information labeling carrier, is pasted into the display groove 14 and can label key information such as the company name and stamp type, facilitating quick identification of the stamp's purpose by the user. This is especially suitable for the categorized management of multiple stamps for a company. To solve the problems of easy wear and tear and difficulty in identification of traditional stamp markings; a transparent plastic plate 5 covers the display groove 14 and the label sticker 13. It is made of highly transparent plastic material, which does not affect the viewing of the label information, and can effectively protect the label sticker 13, preventing it from being worn, contaminated or falling off during use, and extending the label's service life; the limiting groove 9 in the positioning and limiting structure component is opened on the inner side wall of the ink pad 1. The groove size is adapted to the outer protruding part of the rubber ring 6. As a key structure to prevent the ink body from falling off, when the ink body 2 is fastened into the ink pad 1, the outer side of the rubber ring 6 is embedded in the groove. The top wall of the groove contacts the rubber ring 6 to prevent the ink body from moving upward. The side wall of the groove restricts the horizontal displacement of the ink body, ensuring that the contact position between the ink surface 7 and the sponge 8 is stable when stamping;

[0024] When using the seal, first identify the label sticker 13 under the transparent plastic plate 5 on the handle 4 to determine the purpose of the seal (e.g., the type of seal corresponding to the company name). Then, press the handle 3 downwards moderately. The pressure is transmitted through the threaded connection, causing the seal surface 7 to squeeze the sponge 8 inside the ink pad 1. The sponge 8 releases the stored ink and evenly adheres it to the seal surface 7. Maintain the pressure, then slowly lift the handle 3 upwards. Next, hold the brass handle 3 with one hand and gently pull it upwards, allowing the seal body 2 to disengage the rubber ring 6 from the limiting groove 9 of the ink pad 1, exposing the seal surface 7 beneath the seal body 2. Next, proceed to the stamping operation. Align the stamp face 7 with the area of ​​the paper to be stamped (such as the designated area of ​​the document) and press the stamp vertically downwards. Then, remove the stamp face 7 from the paper to complete the printing of a clear mark. Finally, reset and store the stamp. After stamping, align the stamp body 2 with the opening of the ink pad 1 so that the outer side of the rubber ring 6 is re-embedded into the limiting groove 9 until the lower surface of the stamp face 7 contacts the upper surface of the sponge 8. At this time, the sponge 8 is compressed and generates an upward supporting force, pushing the stamp body 2 so that the rubber ring 6 is in close contact with the top wall of the limiting groove 9, completing the limiting and fixing to prevent the stamp body 2 from falling off. This completes the use.

[0025] Working principle: The copper stamp pad 1 is positioned by the rubber ring 6 of the stamp body 2 through the limiting groove 9. The inner side of the rubber ring 6 is fixed to the rubber ring positioning groove 10, and the outer side is embedded in the limiting groove 9 to avoid direct friction between the copper parts. The 4:1 hot-pressed sponge 8 inside the stamp pad stores the ink. When the stamp is closed, it generates an upward force to strengthen the fit between the rubber ring and the limiting groove and prevent it from falling off. When in use, pull the handle 3 to detach the stamp body 2 from the stamp pad, press the handle to make the stamp surface 7 squeeze the sponge to absorb the ink, and then contact the paper to complete the stamping. When resetting, the stamp body 2 returns to its original position, the rubber ring 6 is embedded in the limiting groove 9, and the elasticity of the sponge 8 helps to fix it, achieving stable operation and long-term use.
