S4: The account payment information calculation security system (4) controls the account information security comparison system (15) to perform security comparison on the payment account information, and then the account payment amount security protection system (16) performs security protection on the property amount to be paid, and finally the payment environment virus fixed-point elimination system (17) performs fixed-point elimination of viruses on the network payment environment to ensure the security of network payment; S5: The information backup system (8) is operated to control the information storage backup system (18) inside the host to use the internal storage system to store the information inside the host, and at the same time, the external mobile storage backup system (19) of the host controls the USB flash drive (40) to perform external storage backup of the information inside the host; S6: When the user needs to control the insertion and removal of the U disk (40), the user pulls the two fixing plates (31) outwards so that the two fixing plates (31) are fixed on the front side of the computer host (20), and the user moves the positioning plate (27), and the positioning plate (27) moves to move the insertion and removal position of the U disk (40), so that the U disk (40) and the USB interface (21) are aligned. After the alignment is completed, the electric push rod (24) is started to work, and the electric push rod (24) contracts to drive the U disk (40) to move downward, so that the U disk (40) is embedded in the USB interface (21). At the same time, the user needs to fix the U disk (40). When fixing or loosening, the user places the USB flash drive (40) between the two clamping plates (39), and turns the knob (36) to rotate. The rotation of the knob (36) drives the rotating rod (35) to rotate. The rotation of the rotating rod (35) drives the threaded rod (37) to rotate. The rotation of the threaded rod (37) drives the two sleeves (38) to move. The movement of the two sleeves (38) drives the two clamping plates (39) to move, so that the two clamping plates (39) clamp and fix the USB flash drive (40). At the same time, turning the knob (36) in the opposite direction can control the two clamping plates (39) to separate, so that the USB flash drive (40) is loosened, which is convenient for the user to disassemble and replace the USB flash drive (40).
