[0040] With reference to Figure 1 , Figure 2The sliding shell 2 is internally provided with a battery for supplying power to the control mainboard 52, and the battery is a rechargeable battery. The side wall of the top shell 3 is provided with a switch button 31 and a charging interface 32. A data line is inserted into the charging interface 32, and the other end of the data line is connected to a power supply to charge the battery.

[0041] The implementation principle of the safe seal of the embodiment of the application is as follows: in normal state, the sliding shell 2 is moved upward under the action of the first spring 24, so that the seal body 4 is retracted into the inner cavity of the bottom shell 1, the linkage rod 27 abuts against the second guide surface 142 to force the hinged lug plate 14 to rotate reversely to make the sealing plate 13 rotate to the horizontal state to close the opening of the bottom shell 1, so that the seal surface information of the seal body 4 cannot be directly obtained, and the lock rod 25 is inserted into the locking hole 12 to effectively limit the downward movement of the sliding shell 2, thereby preventing unauthorized stamping behavior.

[0042] When stamping is needed, the device is started by the switch button 31, and after the mobile terminal scans the two-dimensional code, the application permission submission program is entered, and the approval person approves the stamping to obtain the stamping permission. After obtaining the stamping permission, the control mainboard 52 controls the electric cylinder 53 to act to drive the lock rod 25 to slide out of the locking hole 12 to realize unlocking, and the display screen displays the stamping frequency limit. The bottom shell 1 is placed at the stamping position, and the user presses the top shell 3 to move the sliding shell 2 downward, thereby driving the seal body 4 to move downward. In the process of moving the sliding shell 2 downward, the linkage rod 27 abuts against the first guide surface 141 to force the hinged lug plate 14 to rotate forward to make the sealing plate 13 rotate to the vertical state. At this time, the sealing plate 13 is located on one side of the inner wall of the bottom shell 1, so that the opening of the bottom shell 1 is in an open state. The sliding shell 2 continues to move downward, and at this time the linkage rod 27 still abuts against the first guide surface 141 to force the sealing plate 13 to always be in the vertical state. When the seal body 4 contacts the stamping paper surface, the sliding shell 2 continues to move downward, thereby forcing the seal body 4 and the installation pedal 6 to move upward relative to the sliding shell 2, so that the installation pedal 6 presses the counting button of the counter 54. At this time, the second spring 63 has elastic potential energy due to elastic deformation. After stamping is completed, the force applied to the top shell 3 is removed, and the first spring 24 forces the sliding shell 2 to move upward relative to the bottom shell 1. In the process of moving the sliding shell 2 upward, the second spring 63 forces the installation pedal 6 to slide and reset, and the linkage rod 27 abuts against the second guide surface 142 to force the hinged lug plate 14 to rotate reversely to make the sealing plate 13 rotate to the horizontal state to close the opening of the bottom shell 1. After the sliding shell 2 slides and resets, the stamping frequency of the touch display screen 51 is consumed once. When the counter 54 reaches the set number of times, the electric cylinder 53 drives the lock rod 25 to slide and be inserted into the locking hole 12 again.

[0043] The above are preferred embodiments of the application, and do not limit the protection scope of the application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the application should be covered within the protection scope of the application.
