A hydraulic hand tool has a first oil-return channel, a second oil-return channel, and an oil-return-controlling mechanism. Hydraulic oil can carry out the oil-return process through the first oil-return channel and the second oil-return channel. The oil-return-controlling mechanism has a control channel, a blocking unit, an elastic unit, a driving assembly, and a control module. The control channel communicates with the first oil-return channel and the second oil-return channel. The blocking unit is mounted in the control channel. The elastic unit presses against the blocking unit to block the control channel and thus isolate the first oil-return channel and the second oil-return channel. The driving assembly is controlled by the control module. The driving assembly makes the blocking unit abut against the elastic unit and move, and thus the first oil-return channel and the second oil-return channel communicate with each other.
