A liquid pressing device includes mainly a power device consisting of a motor with a spindle, an upper cap on the motor and a lower cap under the motor, a shell for containing the power device, a helical device fitted around the spindle of the motor and having a conical body and a plurality of helical leaves around the conical body. The helical leaves spiral down to form a helical groove between every two helical leaves for water to pass through. The helical leaves have thickness gradually becoming thinner and thinner downward, and the helical grooves gradually become narrower and narrower downward to add pressure to water flowing up therein. Then the conical member functions to add second pressure to water passing through, sending it to a very high location. Then the liquid pressing device can function as a water pump or a propeller.
