Embodiment 1
[0030] First, copy the data in the block chain to the storage device 2 for storage; then collect the user's fingerprint through the fingerprint collector 6, when the fingerprint is correct, the locking mechanism 8 operates, and the electric telescopic rod 82 drives the insertion rod 83 Pull out from the slot 87, also shrink in the second groove 81, move the cover plate 7, the cover plate 7 drives the block 86 to be drawn out from the card slot 85, and the box body 1 can be opened; then the storage device 2 is placed in the box Inside the body 1, and the left side of the reservoir 2 is in contact with the first splint 3, the clamping mechanism 5 operates, the motor 52 drives the threaded rod 53 to rotate, and the cooperation of the threaded rod 53 and the threaded tube 54 drives the second splint 4 to move. The second splint 4 is in contact with the storage 2 to fix the storage 2; finally, after the storage 2 is fixed, the cover plate 7 is closed to facilitate the protection and...
Embodiment 2
[0032] In embodiment one, add following operation:
[0033] In step A, storage devices 2 with different storage capacity can be selected according to the size of the data.
[0034] First, copy the data in the block chain to the storage device 2 for storage, and select storage devices with different storage capacity according to the size of the data; then collect the user's fingerprint through the fingerprint collector 6, when the fingerprint is correct, The locking mechanism 8 operates, and the electric telescopic rod 82 drives the insertion rod 83 to be extracted from the slot 87, and also shrinks in the second groove 81, and the cover plate 7 is moved, and the cover plate 7 drives the block 86 to be extracted from the draw-in slot 85. The box 1 can be opened; then the storage 2 is placed in the box 1, and the left side of the storage 2 is in contact with the first splint 3, the clamping mechanism 5 operates, the motor 52 drives the threaded rod 53 to rotate, and the threaded...
