A shock-resisting device includes a snubber that may be selectively moved from a retracted position to an engaged position to selectively create a stiff attachment between a vibration-isolated gimbal of the device, and an outer shell of the device. The gimbal is movable relative to the outer shell. The snubber includes a retainer maintaining the snubber in the retracted position, wherein the snubber is configured to move from the retracted position to the engaged position in response to loss of power to the retainer.

The present invention is related to a triaxial micro-electromechanical gyroscope, comprising: a ring-shaped detection capacitor located at the center; two sets of driving capacitors located at outer sides of the ring-shaped detection capacitor and symmetrically distributed at two sides of an origin along a y-axis; two sets of second detection capacitors located at the outer sides of the ring-shaped detection capacitor respectively and symmetrically distributed at the two sides of the origin along an x-axis; and a linkage part connected with movable polar plates of the driving capacitors, movable polar plates of the second detection capacitors, and an outer edge of ring-shaped upper polar plates of the ring-shaped detection capacitor, respectively. The triaxial micro-electromechanical gyroscope provided by the present invention adopts a single structure design, and integrates capacitive electrostatic driving and differential capacitive detection.
