Claim 9:
10. The posture adjustment method of claim 8, wherein the movable bracket comprises a first movable plate, a second movable plate and a third movable plate; the plurality of piezoelectric adjusting bolts comprise a first piezoelectric adjusting bolt, a second piezoelectric adjusting bolt, a third piezoelectric adjusting bolt, a fourth piezoelectric adjusting bolt, a fifth piezoelectric adjusting bolt, a sixth piezoelectric adjusting bolt, a seventh piezoelectric adjusting bolt and an eighth piezoelectric adjusting bolt; the first movable plate and the second movable plate are located on two opposite sides of the optical sensor to be detected; the first movable plate is connected with the fixed bracket through the first piezoelectric adjusting bolt and the second piezoelectric adjusting bolt; the second movable plate is connected with the fixed bracket through the third piezoelectric adjusting bolt and the fourth piezoelectric adjusting bolt; the third movable plate is connected with the first movable plate through the fifth piezoelectric adjusting bolt and the sixth piezoelectric adjusting bolt; and the third movable plate is further connected with the second movable plate through the seventh piezoelectric adjusting bolt and the eighth piezoelectric adjusting bolt;
when lengths of the fifth piezoelectric adjusting bolt, the sixth piezoelectric adjusting bolt, the seventh piezoelectric adjusting bolt and the eighth piezoelectric adjusting bolt are increased simultaneously, the fixed bracket drives the optical sensor to be detected to move along a negative direction of the first straight line direction; or, when lengths of the fifth piezoelectric adjusting bolt, the sixth piezoelectric adjusting bolt, the seventh piezoelectric adjusting bolt and the eighth piezoelectric adjusting bolt are reduced simultaneously, the fixed bracket drives the optical sensor to be detected to move along a positive direction of the first straight line direction.
