This invention relates to a fishtail-type propeller propeller, comprising a base for fixing to a hull, a rotating shaft vertically supported on the base and rotatable relative to the base, and a vertically mounted propeller plate. A laterally extending connecting rod is fixed to the rotating shaft. The invention is characterized by: a limiting seat fixed to the connecting rod, the limiting seat having a vertically extending shaft hole in which a pin is installed; the propeller plate being fixed to the pin and located below the limiting seat; a limiting member also being provided on the pin; and an arc-shaped movable space centered on the pin and a limiting part inserted into the arc-shaped movable space between the limiting member and the limiting seat. The propeller plate rotates relative to the limiting seat within the range defined by the arc-shaped movable space via the pin. This invention allows the propulsion of the hull to come from the combined force of the flexible connection between the water flow and the propeller plate and the rigid connection between the rotating shaft and the propeller plate, which, under the same conditions, helps to increase the forward speed of the hull and is easy to operate.
