During this period, the harmonic reducer 5 can ensure the accuracy and stability of the transmission. The liquid metal cavity 1501 and piezoelectric ceramic fine adjuster 1502 on the adaptive leveling and vibration damping support 15 can level the base 1. At the same time, the viscoelastic damping layer 1503 can absorb and weaken the energy of high-frequency vibrations transmitted to the adaptive leveling and vibration damping support 15 by utilizing the high loss factor of the material, so as to reduce the negative impact of vibration. This facilitates the adjustment of the XYZ axes with high accuracy and can also reduce vibration to reduce the negative impact of vibration.
