We revisit the moving groups (MGs) in the solar neighborhood with a sample of91969 nearby stars constructed from LAMOST DR7. Using the wavelet technique andMonte Carlo simulations, five MGs together with a new candidate located at $V\simeq$ -130 km s$^{-1}$ are detected simultaneously in $V-\sqrt{U^2+2V^2}$space. Taking into account the other known MGs, we conclude that MGs in theGalactic disk are spaced by approximately 15 $\sim$ 25 km s$^{-1}$ along $V$velocity. The origin of detected MGs is analysed through the distributions of[Fe/H]$-$[Mg/Fe] and ages. Our results support attributing the origin to thecontinuous resonant mechanisms probably induced by the bar or spiral arms ofthe Milky Way.
