A magnetically conductive metal sheet is built into the magnetic groove 4. A magnet array that cooperates with the magnetically conductive metal sheet is provided at the bottom of the display screen 5. A wireless signal transceiver and controller are provided inside the main keyboard 2, which are electrically connected to both the display screen 5 and the numeric keypad 3. The main keyboard 2 and the numeric keypad 3 are connected to the controller through the wireless signal transceiver, and the keyboard status information is displayed on the display screen 5. Since the wireless transceiver and the display screen on the keyboard are existing technologies, they are not described in detail. A snap-fit ​​mechanism that cooperates with the main keyboard 2 and the numeric keypad 3 is provided inside the keyboard base 1.

[0028] See Figure 5 , Figure 6 , Figure 7 , Figure 9 The locking mechanism includes slide rail grooves 6 formed on the inner walls of both sides of the keyboard base 1. Each slide rail groove 6 is slidably adapted to the ends of both the main keyboard 2 and the numeric keypad 3. Five positioning blocks 7 are provided on the other side of the keyboard base 1. The outer side surface of the numeric keypad 3 has side positioning grooves 8 that cooperate with the positioning blocks 7. The outer side surface of the main keyboard 2 has end positioning groove 1 9, middle positioning groove 10, middle positioning groove 2 11, and end positioning groove 2 12, respectively. The middle positioning groove 10, middle positioning groove 2 11, end positioning groove 1 9, and end positioning groove 2 12 are all adapted to the positioning blocks 7. Through the design of the positioning blocks 7, side positioning grooves 8, end positioning groove 1 9, middle positioning groove 10, and middle positioning groove 2 11, when the main keyboard 2 and numeric keypad 3 are adapted to the keyboard base 1, the main keyboard 2 and numeric keypad 3 can be slidably fitted. The keypad 3 serves to limit and fix the position. Specifically, when the main keyboard 2 is on the left and the numeric keypad 3 is on the right, the four positioning slots 12, 11, 9, and 10 on the left side of the main keyboard 2 are connected to the four positioning blocks 7 on the left side, while the 12 on the right side is left unused. The side positioning slot 8 on the numeric keypad 3 is connected to the positioning block 7 on the right side. The main keyboard 2, numeric keypad 3, and keyboard base 1 are connected and fixed together. When the numeric keypad 3 is on the left and the main keyboard 2 is on the right, the side positioning slot 8 on the numeric keypad 3 is connected to the positioning block 7 on the left side, while the two positioning slots 12, 10, and 9 are connected to the four positioning blocks 7 on the right side, while the 11 on the right side is left unused. The main keyboard 2, numeric keypad 3, and keyboard base 1 are connected and fixed together.

[0029] See Figure 5 , Figure 6 and Figure 8 The locking mechanism further includes several locking cavities 13 formed inside the keyboard base 1. Each locking cavity 13 has a connector extending through to the outer surface of the top of the keyboard base 1 on one side of its top. A locking block 14 is laterally slidably connected within the locking cavity 13. A spring 16 connects the outer surface of the locking block 14 away from the connector to the inner wall of the locking cavity 13. One end of a traction rope 20 is connected to the middle of the outer surface of the locking block 14, and the other end of the traction rope 20 extends movably through the keyboard. The outer side of the base 1 is connected and fixed to the pull plate 17. A baffle 18 is vertically inserted into the insertion interface. The baffle 18 has a snap-fit ​​groove 19 on the outer side surface of one end inside the locking cavity 13, which cooperates with the snap-fit ​​block 14. The top of the snap-fit ​​block 14 has an inclined surface 15. One end of several baffles 18 located above the keyboard base 1 abuts against the outer side surface of both the main keyboard 2 and the numeric keypad 3. The bottom of the locking cavity 13 has a groove that matches the bottom end of the baffle 18. The provided grooves allow users to adjust the left and right positions of the numeric keypad 3 and main keypad 2 within the keyboard base 1 according to their usage habits. Specifically, by pulling the pull plate 17 and actuating the traction rope 20, the locking block 14 disengages from the locking groove 19 on the baffle 18. At this point, the baffle 18 can be removed from the locking cavity 13 on the keyboard base 1. Afterward, the main keypad 2 and numeric keypad 3 are no longer restricted by the baffle 18 and can be removed from the keyboard base 1 for further position adjustment. After the position adjustment, the main keypad 2 and numeric keypad 3 can be repositioned. 3. Install the slide rail 6 into the keyboard base 1. Then, insert the baffle 18 into the locking cavity 13 along the insertion hole. During the insertion process, the bottom of the baffle 18 will press the inclined surface 15 of the locking block 14, thereby pushing the locking block 14 to move laterally. When the locking groove 19 on the baffle 18 descends to match the locking block 14, the locking block 14 will reset and move under the action of the spring 16 and lock into the locking groove 19 again. The right-angle end face of the bottom of the locking block 14 fits together with the locking groove 19 to form a stable limiting mechanism.

[0030] The circuits, electronic components, modules, and controllers involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.

[0031] During use, the left and right positions of the numeric keypad 3 and the main keypad 2 within the keyboard base 1 can be adjusted according to the user's habits. Specifically, by pulling the pull plate 17 and moving the traction rope 20, the locking block 14 is disengaged from the locking groove 19 on the baffle 18. At this point, the baffle 18 can be removed from the locking cavity 13 on the keyboard base 1. After this, the main keypad 2 and the numeric keypad 3 are no longer restricted by the baffle 18 and can be removed from the keyboard base 1. Then, their positions can be adjusted. After the position adjustment, the main keypad 2 and the numeric keypad 3 can be moved along... The slide rail 6 is installed into the keyboard base 1. Then, the baffle 18 is inserted into the locking cavity 13 along the insertion hole. During the insertion process, the bottom of the baffle 18 will press against the inclined surface 15 of the locking block 14, thereby pushing the locking block 14 to move laterally. When the locking groove 19 on the baffle 18 descends to match the locking block 14, the locking block 14 is reset and moved under the action of the spring 16 and is locked into the locking groove 19 again. The right-angle end face of the bottom of the locking block 14 fits together with the locking groove 19 to form a stable limiting mechanism.
