The relevant content in the above technical solution is explained as follows:

1. slide rail-slider structure: the stamp is characterized in that the stamp is a common mechanical structure, and the specific arrangement mode is various, for example, a slide rail is arranged on the inner wall of a shell, a slide block is arranged on the side wall of a stamp body, or the slide block is arranged on the inner wall of the shell, the slide rail is arranged on the side wall of the stamp body, and the like; in addition, the matching form can be various, such as an inward concave sliding rail, an outward convex sliding block, an outward convex sliding rail, an inward concave sliding groove structure and the like; the above-mentioned various common deformation structures are essentially the same as the "slide rail-slide block structure" defined in the present application.

2. A limiting component: the limit structure can be a limit groove arranged on the base and matched with a limit bulge on the shell, or a limit groove arranged on the shell and matched with a limit bulge on the base; or a limiting bulge is arranged on the sliding rail or the movable range between the base and the shell is limited by the length of the sliding rail.

4. The transmission end and the driving end are magnetically attracted: the extrusion block and the driving block can be made of magnetic materials which can be mutually attracted, or magnetic units which can be mutually attracted are embedded on the transmission end and the driving end.

5. A limiting support: the device belongs to a common limiting structure and can be in various specific forms or structures, such as a limiting track or a sliding rod; as long as the sliding direction of the extrusion block can be limited, so that the extrusion block can be close to or far away from the elastic suction ball in the direction opposite to the elastic suction ball.

6. The extrusion block extrudes and releases the elastic suction ball: the number of the squeezing blocks can be multiple, for example, two squeezing blocks are symmetrically distributed on two sides of the elastic suction ball, and the two squeezing blocks synchronously move relative to each other and squeeze the elastic suction ball to be flat; or only one movable extrusion block moves towards the elastic suction ball to promote the elastic suction ball to become flat and flat; or the extrusion block is matched with an extrusion plate and other structures fixed in the shell, so that the elastic suction ball is extruded to be flat and shriveled; in summary, the squeezing and releasing of the squeezing blocks to the elastic suction ball can be realized in various specific matching modes, as long as the volume of the elastic suction ball can be changed through the reciprocating sliding of a proper number of squeezing blocks.

Preferably, the number of the extrusion blocks is two, and the extrusion blocks are symmetrically distributed on two sides of the elastic suction ball; each extrusion block is matched with one driving block, and the two driving blocks are symmetrically distributed on the base; when the driving block pushes the extrusion blocks to slide, the two extrusion blocks synchronously extrude the elastic suction ball relatively, and the elastic suction ball is extruded and flat-shriveled.

Preferably, the seal on the engraving plate protrudes out of the engraving surface, a capillary layer is adhered to the surface of the protruding seal, and a waterproof sealing layer is coated on the recessed background area of the engraving plate; the capillary layer can enable the supplementary printing liquid flowing out of the drainage tubule to be uniformly distributed on the surface of the seal imprint, so that the seal pattern is uniform in color and clear in pattern; the waterproof sealing layer can effectively prevent the supplementary printing liquid from being printed on the background part, so that the contrast and the cleanliness of the seal are improved; while reducing liquid residue.

Preferably, the elastic micro-beads are arranged in the elastic resorption cavity, and the elastic micro-beads form capillary gaps in the elastic resorption cavity; the structure can enhance the suck-back capability of the elastic suck-back cavity, can suck back residual liquid in the drainage tubule efficiently, and meanwhile, the elastic microspheres can promote the elastic suck-back cavity to be reset and swelled better.

Preferably, the elastic suction ball is shaped like an oblate ellipsoid, and the flat surface of the oblate ellipsoid is opposite to the extrusion end of the extrusion block; the structure can improve the extrusion sensitivity of the supplementary printing liquid, thereby facilitating the outflow and adjustment of the liquid.

The principle and advantages of the invention are as follows: the seal provided by the scheme is provided with the seal liquid, and a inkpad box is not required to be prepared when the seal is carried and stored, so that the seal is simpler and more convenient to store and use as a whole; when the stamping device is used, a proper amount of printing liquid can be intelligently and automatically extruded and supplied to the engraving surface, so that a clear and complete stamp pattern is formed, the flow of the printing liquid extruded by the elastic suction ball every time is stable, the definition of the stamping pattern is kept stable, the situation that stamping is not clear or is too thick is avoided, and the stamping quality is effectively improved; after the stamp is used, the elastic resorption cavity can resorb and collect the residual supplementary stamp fluid, so that the stamp fluid is prevented from remaining on the engraving surface, the stamp can be conveniently wiped and cleaned, the large-area pollution of the stamp fluid to clothes or a box body can be avoided, and the cleanness and the refreshness of the stamp can be effectively ensured; in conclusion, the seal is convenient to carry and store, liquid can be discharged intelligently and stably, and the stamped patterns are clear and complete; the use and the storage are not easy to be stained, and the whole use process is more concise and refreshing; the overall use experience of the seal can be improved.
