[0048] The utility model realizes the application of using numeric keys for the left or right hand on the same keyboard by installing the sub-keyboard 200 on the left or right side of the main keyboard 100. When the sub-keyboard 200 is installed on the left side of the main keyboard 100, it needs to be plugged into the slide frame 120. The sub-keyboard 200 is pushed to move in the slide frame 120, and the magnetic ball groove 230 and the iron metal ball 125 are adsorbed. Then, the sub-keyboard 200 and the slide frame 120 are pushed at the same time, so that the sub-keyboard 200 and the main keyboard 100 are connected. The magnetic sheet 240 on the sub-keyboard 200 is adsorbed with the iron sheets 104 on the left and right sides of the main keyboard 100. Then, move the push plate 221 on the sub-keyboard 200 to make the plug ring 220 plug into the clamping component North 0, and the spring 2 132 causes the left clamp plate 133 and the right clamp plate 135 to open or tighten through force, so that the plug ring 220 is not easy to fall off when plugged into the clamping component North 0, and then the sliding frame 120 on the right side of the main keyboard 100 can slide to the left to allow the metal block 126 and the magnetic block 103 to be adsorbed, so that the right side sliding frame 120 can be fixed on the right side of the main keyboard 100, so that the sliding frame 120 is not easy to fall off, and repeat the above operation when the sub-keyboard 200 needs to be installed on the right side of the main keyboard 100.

[0049] Example 2, please refer to Figure 2 Figure 15 , curved grooves 140 are provided on both sides of the main keyboard 100, and two groups of curved grooves 140 are provided, which are symmetrically provided. Curved grooves 250 are provided on both sides of the auxiliary keyboard 200, and two groups of curved grooves 250 are provided, which are symmetrically provided.

Paddles 260 are movably installed on both sides of the auxiliary keyboard 200, and two groups of paddles 260 are provided. A fan-shaped bar 261 is fixedly installed at the bottom of the paddle 260, and the fan-shaped bar 261 is plugged into the inner wall of the curved groove 250. The paddle 260 is slid to move the fan-shaped bar 261 to the curved groove 140, so that the main keyboard 100 and the auxiliary keyboard 200 are fixed, so that the patent technology is correctly implemented.

[0050] Through the above technical solution, when the sub-keyboard 200 of the utility model is installed on the left or right side of the main keyboard 100, the paddle 260 is moved to move the fan-shaped strip 261 in the curved groove 250 to the curved groove 1 140, so that the sub-keyboard 200 is fixed on the left side of the main keyboard 100, thereby improving the connection stability between the main keyboard 100 and the sub-keyboard 200.
