Claim 14:
15. The posture adjustment method of claim 8, wherein
adjusting the length of the piezoelectric adjusting bolt comprises a first elongating stage, a second elongating stage, a third elongating stage, a fourth elongating stage and a fifth elongating stage;
in the first elongating stage, providing the power supply to the first piezoelectric stack, and controlling the first piezoelectric stack to elongate, so that the first clamping arm releases the driving rod, and the driving rod remains static;
in the second elongating stage, providing the power supply to the third piezoelectric stack, and controlling the third piezoelectric stack to elongate towards a side close to the second piezoelectric stack, so that the second piezoelectric stack drives the driving rod to shift towards a side away from the first piezoelectric stack, and the driving rod drives the movable screw rod to shift towards a side away from the fixed screw rod;
in the third elongating stage, stopping providing the power supply to the first piezoelectric stack, but providing the power supply to the second piezoelectric stack, controlling the first piezoelectric stack to shorten, and controlling the second piezoelectric stack to elongate towards a side close to the first piezoelectric stack, so that the first clamping arm clamps the driving rod, the second clamping arm releases the driving rod, and the driving rod remains static;
in the fourth elongating 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 first piezoelectric stack, so that the second piezoelectric stack shifts towards the side close to the first piezoelectric stack, and the driving rod remains static; and
in the fifth elongating stage, stopping providing the power supply to the second piezoelectric stack, and controlling the second piezoelectric stack to shorten, so that the second clamping arm clamps the driving rod to fix the position of the driving rod.
