The invention relates to a manpower ship propeller, and particularly relates to a bionic fishtail oar which can effectively push a boat to move forwards through up-and-down shaking. The bionic fishtail oar can be installed at the stern or the prow. The bionic fishtail oar comprises a fixing frame, a crow bar frame, a handle, a lifting rod, a tail blade connecting piece and a fishtail blade, wherein the fixing frame is used for being fixed to the stern or the prow, and the crow bar frame is connected with the fixing frame through a shaft and a bearing and can change the angle with a hull; the crow bar frame is a parallelogram frame with a changeable angle, bearings are embedded in four connection points of the crow bar frame, one side of the crow bar frame is connected with the handle, andthe other side of the crow bar frame can be in linkage with the lifting rod to perform vertical lifting motion; the fishtail blade can form a downward or upward angle along with ascending or descending of the lifting rod, and forward thrust is generated. Compared with the traditional oar and paddle, the bionic fishtail oar has the characteristic that the boat is enabled to be more stable in driving, higher in speed and more convenient to operate being applied to the boat.

    本发明涉及一种人力船用推进器,特别涉及一种利用上下摇动能有效推动小船前行的仿生鱼尾橹;它可以安装在船尾,也可以安装在船头。仿生鱼尾橹:包括固定架、撬杆架、手柄、升降杆、尾叶连接件、鱼尾叶,固定架用于固定在船尾或船头,撬杆架通过轴和轴承与固定架连接,可与船身变化角度;撬杆架是一个可变化角度的平行四边形框,其四个接点都镶有轴承,撬杆架的一侧连接手柄,另一侧可连动升降杆作上下垂直升降运动。鱼尾叶随着升降杆的上升或下降会形成向下或向上的角度,并产生前推力。本发明用在小船上,与传统的橹和桨相比,具有使小船行驶更稳,速度更快,操作更方便的特点。
