Rapid measuring instrument for deflection angle of airplane control surface

The utility model discloses an airplane control surface deflection angle rapid measuring instrument which comprises a first measuring scale and a second measuring scale, one end of the first measuring scale and one end of the second measuring scale which are away from the surface are respectively and fixedly provided with a first fixing arm, and the bottom of the first fixing arm is movably provided with a hinge arm. And a second fixed arm is movably arranged at the top of the hinge arm. According to the utility model, only one of the first measuring scale and the second measuring scale is attached to the reference surface to serve as the reference surface, and then the other one is attached to the control surface of the wing, so that the included angle between the first measuring scale and the second measuring scale is the deflection angle to be measured; when the included angle between the first measuring scale and the second measuring scale changes, the second measuring scale can drive the measuring shaft
