When the U-shaped sliding frame 1 is pressed downwards, the U-shaped sliding frame 1 drives the turnover shaft 71 and the stamp 20 to move downwards synchronously, meanwhile, the sliding block 73 moves from bottom to top along the second track groove 521, when the turnover shaft 71 moves to the bending part 723 of the first track groove 72, the turnover shaft 71 continues to move downwards to the second vertical part 722 under the pressing effect of the U-shaped sliding frame 1, due to the shielding effect of the end part of the second track groove 521 on the sliding block 73, the sliding block 73 cannot continue to move upwards, at the moment, the second track groove 521 drives the turnover shaft 71 to rotate 180 degrees by taking the sliding block 73 as the center, and the turnover shaft 71 drives the stamp 20 to turn over synchronously.

The implementation principle of the embodiment is as follows: the U-shaped sliding frame 1 is pressed downwards, the U-shaped sliding frame 1 moves downwards along the length direction of the U-shaped guide frame 2, the U-shaped sliding frame 1 drives the turnover shaft 71 and the stamp 20 to move downwards synchronously, the sliding block 73 moves from bottom to top along the second track groove 521, when the turning shaft 71 moves to the bending part 723 of the first track groove 72, the slider 73 abuts against the upper side wall of the second track groove 521, the turning shaft 71 continues to move downwards under the pressing action of the U-shaped sliding frame 1, moves to the second vertical part 722 through the bending part 723, due to the shielding effect of the second track groove 521 on the sliding block 73, the sliding block 73 cannot move upwards continuously, at this time, the second track groove 521 drives the turning shaft 71 to rotate 180 degrees by taking the sliding block 73 as a center, so that the stamp 20 can be turned over, then the U-shaped turnover frame 5 drives the stamp 20 to continuously move downwards along the length direction of the U-shaped guide frame 2 to form a print on the paper.

When the external force is removed, the U-shaped sliding frame 1 drives the U-shaped turnover frame 5 to move upwards to the bending part 723, the U-shaped turnover frame 5 is driven to drive the stamp 20 to reversely turn over, the upper surface of the stamp 20 is attached to the lower surface of the ink pad 10, and the action that the stamp 20 is stained with inkpad is completed to prepare for stamping.

When ink needs to be added to the ink pad 10, the operating rod 100 is pulled, the operating rod 100 drives the limiting rack 622 to be disengaged from the gear 621, the rotating shaft 61 is driven to rotate, the rotating shaft 61 drives the gear 621 to rotate, the gear 621 drives the sliding rack 200 to move towards the side wall close to one side of the installation cavity 6231, when one side of the sliding rack 200 abuts against the inner wall of the installation cavity 6231, the movement of the sliding rack 200 is limited, the gear 621 cannot continue to rotate, the gear 621 drives the rotating shaft 61 to rotate to a certain angle and then stops rotating, at the moment, the ink pad 10 is turned over for 180 degrees, external force is removed, the compression spring 624 drives the limiting rack 622 to return to the original position, the limiting rack 622 and the gear 621 are re-engaged, and limitation on the rotating shaft. At this moment, the oil absorption cotton 30 of ink pad 10 is located the lower extreme of oiling pipe 40, and the stamp-pad ink drips into the oil absorption cotton 30 through oiling pipe 40, and the stamp-pad ink evenly spreads on oil absorption cotton 30 to the person of facilitating the use adds the stamp-pad ink operation, and the in-process of whole dropwise add stamp-pad ink, stamp-pad 10 do not contact with operating personnel or other external instrument, avoids the stamp-pad ink to pollute.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
