The invention discloses a restoring device of a Zhang Heng seismograph. The restoring device comprises a shell, a column, a bottom lifting unit, eight groups of swing amplifying units and eight balls. According to the restoring device of the Zhang Heng seismograph, the bottom lifting unit is used for lifting the bottom of the column and enabling the bottom surface of the column to be kept in a horizontal state, so that the axis of the column is always kept vertical, errors caused by swinging are reduced, the measurement accuracy of the seismograph is improved, and meanwhile, the bottom lifting unit adopts a brand new composite swinging structure, so that the reliability of the seismograph is improved. The all-round column can freely shake in the shell after receiving earthquake fluctuation, so that the seismograph has enough sensitivity; shake is amplified through the eight sets of swing amplification units, so that the slight shake of the column can enable the ball on the corresponding ...
