A liquid distribution module includes a housing, a first connecting portion, at least one liquid driving unit and at least one handle assembly. The first connecting portion is disposed in the housing. The fluid driving unit is adapted to be arranged in the housing and includes a second connecting portion. The handle assembly is pivotally connected to the fluid driving unit and adapted to drive the fluid driving unit by force to switch between a free state and a fixing state. When the fluid driving unit is in the free state, the handle assembly is adapted to drive the fluid driving unit to slide relative to the housing. When the fluid driving unit is in the fixing state, the fluid driving unit is fixed in the housing so that the second connecting portion is docked with the first connecting portion.
