The invention relates to a hydroplane tool, in particular to a biomimic umbrella-type paddle, belonging to the technical field of the structure of the paddle. The umbrella-type paddle comprises a paddle handle and a paddle umbrella and is characterized in that the paddle umbrella is opened into the round shape and is composed of a piece of umbrella cloth and supports; the supports are uniformly distributed on the round umbrella cloth; the paddle umbrella is fixed on the paddle handle by a support disk; the supports of the paddle umbrella are firmly connected on the support disk by support shafts, so that the paddle umbrella can be opened or closed freely; a control cord used for controlling the maximum opening degree of the umbrella cloth is connected between the supports of the opening/closing inner surface of the paddle umbrella, so as to prevent overturning caused by overlarge stress. In the invention, with the adoption of the biomimic principle, the umbrella-type paddle has simple and reasonable structure, can be operated without adopting the technology and can be grasped very easily.
