Claim 6:
7. The three-axis micromachined gyroscope as described in claim 6, wherein the connection assembly further comprises four first connection beams and four outer coupling members for connecting the connection rod and the weight; each outer coupling member is connected to one of the first connection beams; each of the connection rods is connected to two of the first connection beams; each of the weights is connected to one of the first connection beams; and the first connection beam is located on the flip axis of each weight;
the first connection beam comprises a fixed part connected with the connection rod, and an extension part separated from the fixed part and connected with the weight; the outer coupling member comprises a second decoupling structure connected between the fixed part and the extension part, a sixth connection beam connecting the rear end of the second decoupling structure and the base;
when the drive electrode drives the weight to swing, the second decoupling structure, the fixed part, and the connection rod do not swing with the weight; when the three-axis micromachined gyroscope receives the angular velocity in the first axis direction and the second axis direction, the second decoupling structure, the fixed part, and the connection rod do not move with the weight under the action of Coriolis; when the three-axis micromachined gyroscope receives the angular velocity in the third axis direction, the second decoupling structure, the fixed part, and the connection rod move in the first axis direction.
