[0003] The patent with the publication number CN200986876Y discloses a computer keyboard and its keycap bracket. Specifically, the patent discloses "a computer keyboard, which includes a keyboard base fixing plate, a keycap, and a keycap bracket installed between the keyboard base fixing plate and the keycap. The keycap is installed above the keyboard bracket. The keycap bracket includes two quadrilateral frames. The middle parts of the two frames are pivotally connected by a pivot to form an "X"-shaped movable bracket. One ends of the two frames close to the keyboard base fixing plate are correspondingly hooked on the keyboard base fixing plate, and one ends of the two frames close to the keycap are correspondingly provided with sliding grooves or bayonets on the keycap", realizing the technical effect of "the combination of the keyboard base fixing plate and the keycap is firm, and when the keycap is pressed, the keycap bracket slides in the card slots of the first sliding hook and the third sliding groove, thereby eliminating the friction between the keycap and the upper cover".

[0004] Although this patent plays a role in increasing the firmness of the keyboard keys by using the X-shaped structure to replace the axial core with a linear stroke in the keyboard during actual use, referring to the prior art, keyboards mainly include mechanical keyboards, membrane keyboards, and capacitive keyboards, etc., among which mechanical keyboards are the mainstream in use, and the use of axial cores with linear strokes can ensure the service life of the keyboard. Therefore, although the X-shaped keyboard key structure has progressiveness, it has obvious defects in service life.

[0005] Therefore, retaining the axial core with a linear stroke in the prior art is a rigid requirement for the use of keyboards in the current state. However, the key base, axial core, and keycap of a mechanical keyboard are stacked in sequence on one side of the keyboard main board, so the volume of the mechanical keyboard is larger than that of the membrane keyboard and the capacitive keyboard, which is inconvenient for storage and carrying.
