1. A keycap support mechanism, for supporting a keycap above a base plate in a vertical direction, the keycap extending lengthwise in a lengthwise direction perpendicular to the vertical direction, the keycap support mechanism as a whole extends lengthwise in the lengthwise direction, the keycap support mechanism comprising:
an outer support; and
an inner support, the outer support and the inner support being pivotally connected around a rotation axis, the rotation axis being parallel to the lengthwise direction, the outer support surrounding the inner support, the inner support comprising a first support body and a first reinforcement part, the first reinforcement part being embedded into the first support body, an elastic modulus of the first reinforcement part being greater than an elastic modulus of the first support body, the inner support defining a first side connection section on both sides of the inner support in the lengthwise direction, each first side connection section comprising at least one base plate connecting portion and at least one keycap connecting portion, the first reinforcement part extending into the two first side connection sections.
