Embodiment 1
[0030] Such as Figure 1-5 As shown, the seal of this embodiment includes a chapter body 1, and the chapter body has a pressing end 1-1 and a chapter surface 1-2, both of which are at opposite ends of the chapter body, and the end surface of the pressing end 1-1 is in a partial spherical shape, The font of the subject's name is engraved on chapter pages 1-2. The outside of the chapter body (the non-both ends, that is, the end face of the non-pressing end 1-1 and the position of the chapter face 1-2) is provided with a fingerprint reader 6, a SIM card slot 2, a camera 3, a display screen 4, a USB interface 5, and a fingerprint The identifier 6, the SIM card slot 2, the camera 3, the display screen 4, and the USB interface 5 are all exposed outside. The fingerprint reader 1 can double as a power switch.
[0031] A cavity 1-3 is formed inside the chapter body, and a control module 7 and a battery 8 are installed in the cavity 1-3. The control module 7 includes a processor, a m...
Embodiment 2
[0040] This embodiment provides another locking device. see Figure 6 , The present embodiment automatic locking device comprises parts such as the miniature servomotor 9-17 that is located in the stamp body 1, fixed wire sleeve 9-18, screw mandrel 9-19, slide rail 9-20. A slidable chapter head 1-6 is arranged in the chapter body 1, and a slide rail 9-20 is provided between the outer walls around the chapter head 1-6 and the inner wall of the chapter body 1. The outward end of the chapter head 1-6 is the chapter face 1-2. Under normal conditions, that is, when the seal is in a locked state, the chapter head 1-6 is retracted into the chapter body 1, that is: the chapter face 1-2 and the chapter body 1 There is a certain distance between the end faces. At this time, because the end faces of the chapter body 1 are blocked, the chapter faces 1-2 cannot be fitted with any external planes, thus the stamping action cannot be completed.

Embodiment 3
[0045] This embodiment provides yet another locking device. see Figure 7 , the automatic locking device of the present embodiment comprises components such as stepper motor 9-22, fixed wire sleeve 9-18, screw mandrel 9-19, slide rail 9-20, pressure sensor 9-21 that are located in stamp body 1 . A slidable chapter head 1-6 is arranged in the chapter body 1, and a slide rail 9-20 is provided between the outer walls around the chapter head 1-6 and the inner wall of the chapter body 1. The outward end of the chapter head 1-6 is the chapter face 1-2. Under normal conditions, that is, when the seal is in a locked state, the chapter head 1-6 is retracted into the chapter body 1, that is: the chapter face 1-2 and the chapter body 1 There is a certain distance between the end faces. At this time, because the end faces of the chapter body 1 are blocked, the chapter faces 1-2 cannot be fitted with any external planes, thus the stamping action cannot be completed. A pressure sensor 9-...
