Abstract
The utility model discloses a propeller mounting seat which comprises a power mechanism, a propeller, a fastener and a first elastic gasket, wherein a first positioning hole is formed in the power output end of the power mechanism; a second positioning hole is formed in a fixed part of the propeller; the first elastic gasket is arranged between the power mechanism and the propeller; a third positioning hole is formed in the first elastic gasket; the fastener passes through the second positioning hole and the third positioning hole to be fixed in the first positioning hole. According to the propeller mounting seat, the first elastic gasket is arranged between the power mechanism and the propeller, so that the propeller can rotate under the action of power generated by the power mechanism; the first elastic gasket is squeezed during the rotation of the propeller so as to provide an internal stress, thereby preventing the first elastic gasket from being further squeezed by the propeller. Thus, the self-correction is realized, i.e., the balance of the propeller is ensured. Meanwhile, the fastener is used for fastening the propeller and the power mechanism, equivalently, and an elastic assembly is additionally mounted on the fastener, so that the fastener is difficultly loosened from the first positioning hole of the power mechanism. As a result, the energy efficiency of the propeller is improved.
