The pressing block 28 is made of rubber material, and the sleeve block 24 is used to support the pressure sensor 27.

[0034] The working principle of the all-in-one computer with a dual-screen structure of the present invention is as follows:

[0035] Step 1: During the operation of the dual-screen structure, the power cable bundle is docked on the connection head 15, and the communication cable bundle is docked on another connection head 15, and then connected to the computer main unit 14 for power supply. Then the operator stands in front of the main screen 2, and the consumer stands in front of the secondary screen 11. The support seat 1 is supported by the bottom case 13, the secondary screen 11 is supported by the support seat 1, and the main screen 2 is supported by the support seat 1. In this way, the face recognition camera 12 collects the face of the operator. After correct recognition, the operator presses the button 9 on the operation keyboard 3 to input the calculation amount, and the product information is displayed through the secondary screen 11 and the main screen 2. At the same time, the consumer can bring the consumption barcode close to the position of the barcode scanning sensor 16, and the consumption is recognized through the barcode scanning sensor 16 to complete the operation of the dual-screen all-in-one computer.

[0036] Step 2: During synchronous safety protection, when the operator is away from the main screen 2 and the face recognition camera 12 does not recognize the face of the operator, and after more than ten seconds, the micro electric cylinder 4 is immediately started by the computer main unit 14. The micro electric cylinder 4 pushes the linkage bar 5 to move left. Please refer to the moving direction. The linkage bar 5 drives a plurality of sliding bars 6 to move left synchronously. The sliding bars 6 move left along the operation keyboard 3. The sliding bars 6 drive the L-shaped cover bar 7 to move left. The L-shaped cover bar 7 makes the docking bar 8 move left. The docking bar 8 is inserted into the inner wall of the locking groove 10, so that the docking bar 8 realizes horizontal plug-in limit for the button 9. At the same time, the top end of the inner wall of the L-shaped cover bar 7 presses on the upper surface of the button 9, and the L-shaped cover bar 7 realizes shielding protection for the button 9. In this way, the multiple buttons 9 on the operation keyboard 3 cannot be operated. When the operator is away from the recognition area of the face recognition camera 12, the multiple buttons 9 can be automatically locked for safety protection to prevent the operator from operating the buttons 9. Figure 4 When the operator is away from the main screen 2 and the face recognition camera 12 does not recognize the face of the operator, and after more than ten seconds, the micro electric cylinder 4 is immediately started by the computer main unit 14. The micro electric cylinder 4 pushes the linkage bar 5 to move left. Please refer to the moving direction. The linkage bar 5 drives a plurality of sliding bars 6 to move left synchronously. The sliding bars 6 move left along the operation keyboard 3. The sliding bars 6 drive the L-shaped cover bar 7 to move left. The L-shaped cover bar 7 makes the docking bar 8 move left. The docking bar 8 is inserted into the inner wall of the locking groove 10, so that the docking bar 8 realizes horizontal plug-in limit for the button 9. At the same time, the top end of the inner wall of the L-shaped cover bar 7 presses on the upper surface of the button 9, and the L-shaped cover bar 7 realizes shielding protection for the button 9. In this way, the multiple buttons 9 on the operation keyboard 3 cannot be operated. When the operator is away from the recognition area of the face recognition camera 12, the multiple buttons 9 can be automatically locked for safety protection to prevent the operator from operating the buttons 9.

[0037] Step 3: During capping protection, when the linkage bar 5 moves left, it will drive the connecting column 17 to move left synchronously. Among them, please refer to Figure 4In the moving direction, the connecting column 17 causes the connecting block 18 to move leftward. The connecting block 18 drives the supporting block 19 to move leftward. Both the supporting block 19 and the connecting block 18 slide leftward along the lower surface of the operation keyboard 3. The supporting block 19 drives the moving bar 20 to move leftward. The moving bar 20 drives the linkage block 23 to move leftward. Both the linkage block 23 and the moving bar 20 drive the cover plate 21 to move leftward. The cover plate 21 slides leftward along the main screen 2. In this way, the cover plate 21 presses on the outside of the power button 22, making it impossible for non-operators to press the power button 22, thus preventing the main screen 2 from being shut down and restarted, and avoiding misoperation of the main screen 2 by non-professionals.

[0038] Step Four: During precise positioning, when the connecting block 18 moves leftward and contacts the pressing block 28, the pressing block 28 is pressed against the sensing end of the pressure sensor 27. The support block 25 supports the support ring 26, and the support ring 26 supports the pressure sensor 27. At the same time, the sleeve block 24 supports the pressure sensor 27. In this way, when the pressure sensor 27 senses the extrusion force, the micro-electric cylinder 4 is turned off. This can ensure that the docking strip 8 is inserted into the locking groove 10 at the specified position, and at the same time, the cover plate 21 presses on the power button 22 at the specified position, achieving precise and safe protection.
