[0010] The utility model is further configured that sliding blocks are fixed on both sides of the bottom of the shaft core, and upper slideways are opened on both sides of the inner wall of the installation position.

[0011] By adopting the above technical solution, the slider is arranged to slide inside the upper slide, and the top of the inner wall of the upper slide limits the movement of the slider to prevent the shaft core from leaving the installation position.

[0012] The utility model is further configured such that a lower slideway is provided on the top of the base.

[0013] By adopting the above technical solution, the movement direction of the shaft core can be limited by the provided lower slide track, so that the slider on the side of the shaft core can slide inside it.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] The utility model uses an axis core, a guide column, a mounting position and a guide groove, and the guide column is slidably connected with the guide groove of the upper cover, so that the axis core is more stable when it moves up and down. A magnet is provided at the end of the axis core for fixed connection, and when the axis core is pressed downward, the bottom of the axis core is usually penetrated by a connecting tube. When in use, the magnet is conveniently magnetically induced by the Hall element on the keyboard PCB integrated circuit to realize keyboard input control. BRIEF DESCRIPTION OF THE DRAWINGS
