[0030] In this technical solution, if Figure 4 - Figure 7 As shown, a cover protection assembly is installed at one end of the linkage bar 5; the cover protection assembly includes a connecting column 17 fixedly installed at one end of the linkage bar 5, and one end of the connecting column 17 is fixedly connected to a connecting block 18, the connecting block 18 is slidably connected to the operation keyboard 3, and a supporting block 19 is fixedly connected to one end of the connecting block 18; the cover protection assembly also includes a moving bar 20, a cover plate 21, a power button 22 and a linkage block 23.

[0031] The moving bar 20 is fixed to one side of the support block 19, the cover plate 21 is fixedly connected to the upper surface of the moving bar 20, the cover plate 21 is slidably connected to the main screen 2, the power button 22 is located on one side of the cover plate 21, and the power button 22 is fixedly connected to the main screen 2, and the linkage block 23 is fixed to one side of the inner wall of the cover plate 21.

[0032] In this technical solution, if Figure 7 - Figure 8As shown, a sleeve block 24 is provided on one side of the moving bar 20, and the sleeve block 24 is fixedly connected to the operation keyboard 3. A support block 25 is provided on one side of the sleeve block 24, and the support block 25 is fixedly connected to the operation keyboard 3. A support ring 26 is fixedly connected to one side of the support block 25. A pressure sensor 27 is fixedly installed on the inner wall of the support ring 26, and the pressure sensor 27 is fixedly connected to the sleeve block 24. A pressure block 28 is fixedly installed on the sensing end of the pressure sensor 27. The pressure block 28 is made of rubber material, and the sleeve block 24 is used to support the pressure sensor 27.

[0033] The working principle of the all-in-one computer with a dual-screen structure of the present invention is as follows: Step 1: When operating the dual-screen structure, connect the power harness to the wiring head 15, and the communication harness to another wiring head 15, so as to connect the computer host 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, and the support 1 is supported by the bottom shell 13, the support 1 supports the secondary screen 11, and the support 1 supports the main screen 2, so that the face recognition camera 12 collects the operator's face. After the recognition is correct, the operator presses the button 9 on the operation keyboard 3 to enter the calculated 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 code scanning sensor 16, and the consumption is recognized by the code scanning sensor 16 to complete the dual-screen computer all-in-one operation.

[0034] Step 2: During synchronous safety protection, when the operator is away from the main screen 2, the face recognition camera 12 does not recognize the operator's face, and after more than ten seconds, the computer host 14 immediately starts the micro cylinder 4, and the micro cylinder 4 pushes the linkage bar 5 to move left. Please refer to Figure 4 In the moving direction, the linkage bar 5 drives the multiple slide bars 6 to move left synchronously, and the slide bars 6 slide left along the operation keyboard 3, and the slide bars 6 drive the L-shaped cover bar 7 to move left, and the L-shaped cover bar 7 makes the docking bar 8 move left, and the docking bar 8 is plugged into the inner wall of the locking groove 10, so that the docking bar 8 realizes the horizontal plugging limit for the button 9. At the same time, the top end of the inner wall of the L-shaped cover bar 7 is pressed on the upper surface of the button 9, and the L-shaped cover bar 7 realizes shielding and protection for the button 9, so that 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 button 9.

[0035] Step 3: When the cover is closed, when the linkage bar 5 moves to the left, the connecting column 17 will move to the left synchronously. Figure 4In the moving direction, the connecting column 17 causes the connecting block 18 to move left, and the connecting block 18 drives the supporting block 19 to move left. Both the supporting block 19 and the connecting block 18 slide left along the lower surface of the operation keyboard 3, and the supporting block 19 drives the moving bar 20 to move left, and the moving bar 20 drives the linkage block 23 to move left. Both the linkage block 23 and the moving bar 20 drive the cover plate 21 to move left, and the cover plate 21 slides left along the main screen 2. In this way, the cover plate 21 covers the outside of the power button 22, so that non-operating personnel cannot press the power button 22, thereby failing to shut down and restart the main screen 2, thereby preventing non-professionals from operating the main screen 2 by mistake.

[0036] Step 4: During precise positioning, when the connection block 18 moves to the left and contacts the pressure block 28, the pressure block 28 is pressed against the sensing end of the pressure sensor 27, and the support block 25 supports the support ring 26, which supports the pressure sensor 27. At the same time, the sleeve block 24 supports the pressure sensor 27, so that when the pressure sensor 27 senses the squeezing force, the micro cylinder 4 is closed, so that the docking strip 8 can be inserted into the locking groove 10 according to the specified position, and the cover plate 21 is pressed on the power button 22 according to the specified position, so as to achieve precise safety protection.
