[0026] A cavity is provided at the lower end of the keycap 1, and a clamping device 1 is provided at the bottom end of the cavity. The clamping device 1 includes a "cross" shaped protrusion 5, a fixing block 1 6 and a cross bar 7. A "cross" shaped protrusion 5 is fixedly installed at the center of the bottom end of the keycap 1, and a cylinder is sleeved on the outer end of the "cross" shaped protrusion 5, and two fixing blocks 1 6 are fixedly installed at both ends of the "cross" shaped protrusion 5, and the two fixing blocks 1 6 are symmetrically arranged, and a cross bar 7 is fixedly sleeved in the center of the fixing blocks 1 6 at both ends.

[0027] A limit plate 8 is fixedly installed at the lower end of the connecting seat 2, and the clamping device 2 at the upper end of the connecting seat 2 includes a latch rod 9, a fixed block 2 10 and a clamping groove 11. A latch rod 9 is fixedly installed in the center of the upper end surface of the connecting seat 2, and a "cross"-shaped groove is opened in the center of the latch rod 9, and the latch rod 9 is equally divided into four pieces. A cylinder is fixedly sleeved at the lower end of the latch rod 9, and two fixed blocks 2 10 are fixedly installed at both ends of the latch rod 9, and the two fixed blocks 2 10 are symmetrically arranged, and a clamping groove 11 is opened in the center of the fixed block 2 10, and protrusions are provided at both ends of the inner wall of the clamping groove 11.

[0028] Furthermore, the "cross" shaped protrusion 5 and the latch rod 9 are latch-matched, and the "cross" shaped protrusion 5 is larger than the latch rod 9. The cross bars 7 at both ends of the "cross" shaped protrusion 5 are movably connected to the clamping grooves 11 at both ends of the latch rod 9 and are fixed by the protrusions at both ends of the inner wall of the clamping groove 11.

[0029] Furthermore, a guide post 12 is fixedly mounted at the center of the limiting plate 8 , and a taper is provided at the front end of the guide post 12 , and a spring 13 is sleeved at the outer end of the guide post 12 .

[0030] Furthermore, a hollow area is opened in the center of the fixing seat 3, and the upper port of the fixing seat 3 is smaller than the lower port, and is movably engaged with the limiting plate 8 at the lower end of the connecting seat 2, and the lower end of the fixing seat 3 is fixedly installed on the upper end of the keyboard body 4.

[0032] Working principle: When installing the keyboard keycap, the operator first plugs the "cross" shaped protrusion 5 at the bottom of the keycap 1 cavity into the corresponding plug rod 9. During the plugging process, the cross bars 7 at both ends of the "cross" shaped protrusion 5 are correspondingly plugged into the clamping grooves 11 at both ends of the clamping grooves 11. The protrusions at both ends of the clamping grooves 11 are fixed. The operator presses the keycap 1 to drive the connecting seat 2 to slide downward, and the guide column 12 set at the bottom of the connecting seat 2 contacts the pressing block 15 to squeeze the conductive element. The part 14 works, and the spring 13 set at the outer end of the guide column 12 rebounds, so that the keycap can be continuously pressed. If the keycap 1 needs to be replaced, the operator needs to use tweezers to clamp the two ends of the keycap 1 and pull it out, so that the "cross" shaped protrusion 5 is separated from the latch rod 9, and the cross bars 7 at both ends are separated from the clamping groove 11 under the upward force. Since the lower end of the connecting seat 2 is fixedly installed with the limit plate 8 and clamped with the fixing seat 3, the keyboard will not be affected when the keycap is pulled out.
