Keycap lifting mechanism

A keycap lifting mechanism, comprising:

• a first support, the first support comprising a first long arm and two first support arms disposed apart, the first long arm extending parallel to an extending direction, the two first support arms protruding from the first long arm non-parallel to the extending direction, the first long arm having a first portion in the extending direction, the first portion being located between the two first support arms and having a first minimum width in a first perpendicular direction perpendicular to the extending direction;
• and
• a second support, the second support comprising a second long arm and a second support arm, the second long arm extending parallel to the first long arm, the second support arm protruding from the second long arm non-parallel to the extending direction, the second support arm and the two first support arms being pivotally connected to each other through a pair of pivots, so that the second support arm and the two first support arms rotate relative to each other around a pivot axis;
• wherein a first distance is defined from the pivot axis to an edge of the first portion away from the pivot axis in the first perpendicular direction, and the first minimum width is 0.4 to 0.67 times the first distance.

• wherein a first distance is defined from the pivot axis to an edge of the first portion away from the pivot axis in the first perpendicular direction, a second distance is defined from the pivot axis to an edge of the second portion away from the pivot axis in the second perpendicular direction, and a ratio value of the first minimum width to the first distance is 0.8 to 1.2 times a ratio value of the second minimum width to the second distance.
