Claim 4:
5. The three-axis micromachined gyroscope as described in claim 4, wherein the vibration part further comprises a connection assembly for connecting the four weights; the connection assembly comprises an inner coupling member that connects each weight to the anchor corresponding to it; the inner coupling member comprises a first decoupling structure, a fourth connection beam connecting the anchor and the first decoupling structure, a fifth connection beam connecting the first decoupling structure and the weight;
when the drive electrode drives the weight to swing, the fourth connection beam and the first decoupling structure swing around the anchor; the first decoupling structure drives the weight to swing around the anchor through the fifth connection beam;
when the three-axis micromachined gyroscope receives the angular velocity in the first axis direction and the second axis direction, the fourth connection beam and the first decoupling structure do not move with the weight under the action of Coriolis;
when the three-axis micromachined gyroscope receives an angular velocity that is perpendicular to the first axis and the third axis of the second axis at the same time, the fourth connection beam and the first decoupling structure do not move with the weight under the action of Coriolis force motion.
