Claim 15:
16. The posture adjustment method of claim 8, wherein
adjusting the length of the piezoelectric adjusting bolt comprises a first shortening stage, a second shortening stage, a third shortening stage, a fourth shortening stage and a fifth shortening stage;
in the first shortening stage, providing the power supply to the second piezoelectric stack, and controlling the second piezoelectric stack to elongate, so that the second clamping arm releases the driving rod, and the driving rod remains static;
in the second shortening stage, providing the power supply to the third piezoelectric stack, and controlling the third piezoelectric stack to elongate towards a side close to the first piezoelectric stack, so that the first piezoelectric stack drives the driving rod to shift towards a side away from the second piezoelectric stack, and the driving rod drives the movable screw rod to shift towards a side close to the fixed screw rod;
in the third shortening stage, stopping providing the power supply to the second piezoelectric stack, but providing the power supply to the first piezoelectric stack, controlling the second piezoelectric stack to shorten, and controlling the first piezoelectric stack to elongate towards a side close to the second piezoelectric stack, so that the second clamping arm clamps the driving rod, the first clamping arm releases the driving rod, and the driving rod remains static;
in the fourth shortening stage, stopping providing the power supply to the third piezoelectric stack, and controlling the third piezoelectric stack to shorten towards a side close to the second piezoelectric stack, so that the first piezoelectric stack shifts towards a side close to the second piezoelectric stack, and the driving rod remains static; and
in the fifth shortening stage, stopping providing the power supply to the first piezoelectric stack, and controlling the first piezoelectric stack to shorten, so that the first clamping arm clamps the driving rod to fix the position of the driving rod.
