Propeller connecting piece for electric model airplane
First Claim
1. A propeller connecting piece for electric model airplane, for connecting an electric-power output shaft with a propeller in an electric model airplane with the propeller, characterized in that the propeller connector comprises two connectors, wherein one of the connectors is connected with the electric-power output shaft of the model airplane, and the other connector is connected with the propeller of the model airplane, one of the two connectors is an elastic component provided with an opening slot, and the two connectors are coaxially connected and can rotate together, but can be separated from each other when impacted by external force, and;
- wherein one of the two connectors has an inner cavity shaped as a drum, the maximal diameter of the cross-sectional circumcircle at the middle of the drum-shaped inner cavity is larger than those of the cross-sectional circumcircles at the bottom and the opening, and the other connector is shaped to be tightly enclosed by the inner cavity of the connector.
