Further, pressure sensors are provided between the 4 suspension rods 52 and the outer plate 51, and the number of the pressure sensors is 4.

In the present embodiment, the applicant found that when a stamp is used, a stack of paper sheets is often stacked together for stamping, and when a document is stacked on the stamp, edges and corners of other paper sheets are padded at the stamp, and a stamp pattern cannot be printed in a region near the edges and corners due to a height difference, fig. 10 shows a state where the paper sheets are stacked, and stamping cannot be performed in a shaded region of fig. 10.

After the intelligent seal obtains the times of multiple times of seal usage, a certain seal cannot be completely sealed due to the situation, a user needs to request the seal usage again, the approval program needs to be operated again, and the working efficiency is reduced.

After the seal is close to the paper surface, the motor 72 drives the rotating ring to rotate, the suspension rods 52 are sequentially pushed, then the four sides of the seal surface are respectively pushed, whether the situation that edges and corners of other paper are padded at the seal position is judged through the data of the pressure sensor, if yes, the number of times of printing is recovered, and the prompt is output, so that repeated printing requests are avoided.

And after detection is finished, the stamp is reversely rotated in the formation process of returning to finish resetting.

s2: the control module controls the bolt 3 of the locking assembly to return;

s3: the control module receives the information of the using times of the seal and accumulates the using times, and when the using times are equal to the stamping times, the control module controls the bolt 3 of the locking assembly to extend out.

Further, the control module is connected with the pressure sensors to obtain pressure values, the real-time pressure values of the 4 pressure sensors are respectively F1-F4, and the F1-F4 are all larger than a threshold FA and then are used for times + 1.

In the specific using process, after obtaining the authorization of using the stamp, the lock tongue 3 retracts, the bottom box 1 is pressed to enable the stamp face to turn out and contact paper, when the paper is contacted, the pressure of F1-F4 is increased and exceeds a threshold FA, the using times of one time are accumulated, and when the using times are equal to the authorized using times, the lock tongue 3 extends out.

Further, the control module controls the motor 72 to rotate, the arc-shaped plates 73 sequentially push the hanging rods 52, and 4 hanging rods 52 are G1-G4;

after the motor 72 drives the rotating ring 71 to rotate by 4 × R1: if any one of Δ F12- Δ F14, Δ F21, Δ F22- Δ F24, Δ F31- Δ F32, Δ F34, and Δ F41- Δ F43 is greater than the threshold value FB, the number of times of use is-1.

In the specific implementation process, if there is a corner where another paper sheet is placed at the stamp, as shown in fig. 10, the left suspension rod 52 is G1 and the right suspension rod 52 is G3 in the direction of the drawing, when the G3 is pushed, since the center of the stamp face is a lever fulcrum, the G1 receives an upward force, and the value of G31 increases beyond the threshold FB, it can be determined that there is a defect in the stamping behavior of this time, the number of times of printing for one time is recovered, and a prompt is output.
