Keycap lifting mechanism and long rectangular keyswitch structure

A long rectangular keyswitch structure, the long rectangular keyswitch structure having a long side direction and a short side direction, the long rectangular keyswitch structure comprising:

• a base plate;
• a keycap, the keycap being disposed above the base plate;
• and
• a keycap lifting mechanism, the keycap lifting mechanism being connected to the base plate and the keycap, the keycap being vertically movable relative to the base plate through the keycap lifting mechanism, the keycap lifting mechanism comprising:
• a first support, the first support comprising a first keycap connection portion and a first base plate connection portion, the first support being connected to the keycap through the first keycap connection portion, the first support being connected to the base plate through the first base plate connection portion;
• and
• a second support, the second support and the first support being pivotally connected around a pivot axis, the pivot axis being parallel to the long side direction, the second support comprising a first outer sliding shaft, a second outer sliding shaft, an inner sliding shaft, a first outer base shaft, and a second outer base shaft, the first outer base shaft being closer to the first outer sliding shaft than the second outer base shaft in the long side direction, the second outer base shaft being closer to the second outer sliding shaft than the first outer base shaft in the long side direction, the inner sliding shaft being located between the first outer sliding shaft and the second outer sliding shaft, the second outer base shaft being located between the second outer sliding shaft and the inner sliding shaft in the long side direction, a distance between the first outer sliding shaft and the first outer base shaft in the long side direction being less than a distance between the second outer sliding shaft and the second outer base shaft in the long side direction, the second outer sliding shaft being closer to the inner sliding shaft than the first outer sliding shaft, the second support being slidably and rotatably connected to the keycap through the first outer sliding shaft, the inner sliding shaft, and the second outer sliding shaft, the second support being rotatably connected to the base plate through the first outer base shaft and the second outer base shaft.
