1. A micromechanical gyroscope, comprising:
a first movement member, the first movement member having a first center, with two ends of the first movement member along a second direction being able to oscillate around the first center along a first direction and a third direction;
a second movement member, the second movement member having a second center, with two ends of the second movement member along the first direction being able to oscillate around the second center in the second direction and the third direction;
a plurality of drive members, being able to drive the first movement member to oscillate along the first direction and the second movement member to oscillate along the second direction; and
a detection member, the detection member being located above or below the first movement member and the second movement member along the third direction, the detection member being configured to detect a distance the first movement member and the second movement member moving along the third direction;
wherein, the first direction is perpendicular to and coplanar with the second direction, and the third direction is perpendicular to the first direction and the second direction.
