[0023] Working principle: When in use, the sliding block 34 is fixed in the sliding frame 37 through the fixing screw 36, so that the connecting sleeve 33 is sleeved on the connecting column 32, and then the chip connector 2 is electrically connected to the external pin 35. By removing the fixing screw 36, the external pin 35 of the chip can be replaced, thus reducing the maintenance cost of the chip. When the chip is connected and running, the central processing module 81 receives the operation instructions transmitted by the device. Subsequently, the set operation switching module 86 opens the corresponding function module of the chip according to the operation instructions transmitted by the central processing module 81, reducing the occupancy rate of the non-essential modules on the chip CPU during the operation process, thereby improving the information processing efficiency of the chip. When using the communication transmission function, the operation switching module 86 opens the communication transmission module 82. Then, the channel establishment module 821 establishes a point-to-point device communication channel. Next, the communication connection module 822 wirelessly connects two devices according to the independent encoding. After the wireless connection, it enters the communication platform module 823. Subsequently, the data exchange module 824 exchanges the data in the devices. The shared file materials are viewed in the shared platform module 825. At the same time, the main body interaction module 826 feeds back the communication interaction process to the central processing module 81, and the central processing module 81 feeds back the communication interaction process to the main body device. When using the card reader function, the operation switching module 86 opens the information reading module 83. Then, the code recognition and interpretation module 831 recognizes the external code. Next, the source file search module 832 views the external source file corresponding to the code. Finally, the file output module 833 transmits the external source file to the central processing module 81, and the central processing module 81 feeds back the external source file to the device main body. When using the card swiping module, the operation switching module 86 opens the intelligent card swiping module 84. Then, the interactive switch module 843 is opened, and the docking detection module 844 detects the card reading device. Next, the card swiping interaction module 845 retrieves the smart card data stored in the digital card storage module 842. Then, the smart card swiping process is completed in the card swiping interaction module 845. Subsequently, the interactive output module 846 feeds back the card swiping result to the central processing module 81, and the central processing module 81 transmits it to the main body device. The set data receiving module 851 is used to receive the externally transmitted data file. Subsequently, the segmentation processing module 852 performs segmentation processing on the data file to process the data file into ordered data packets. Next, the encryption processing module 853 encrypts each data packet. Then, the storage library module 855 stores the data, adding an encrypted storage function to the chip, enriching the functionality of the chip, meeting the personalized needs of users, and improving the practicality of the chip. When storing, the path storage module 854 records the storage path of the data packet. When it is necessary to call the stored data, the data retrieval module 856 receives the data retrieval instruction. Subsequently, in combination with the storage path of the data packet stored in the path storage module 854, the corresponding data packet is retrieved from the storage library module 855. Then, the decryption output module 857 restores the ordered data packets to the original data.And it is transmitted to the central processing module 81, and then transmitted by the central processing module 81 to the main device for data display.
