Background

At present, the control surfaces and control shafts of various micro aircrafts are connected by square shafts, and the side length of each square shaft is less than 12 mm. In order to ensure the control precision of the steering engine on the control surface, the key link is to reduce or eliminate the connection clearance between the square shaft of the control surface (hereinafter referred to as square shaft) and the square hole of the steering engine (hereinafter referred to as square hole). In the past, in order to reduce or eliminate the connecting gap between the square shaft and the square hole, a method of improving the accuracy of the square shaft and the square hole and then selecting and matching is mainly adopted. However, because the rotation radius of the square shaft is small, the connection clearance between the square shaft and the square hole still obviously influences the control precision of the steering engine on the control surface, and the high precision requirement of the square shaft and the square hole brings great processing difficulty and economic cost for production.

Therefore, the inventor provides a connecting structure which can accurately measure and position the connection between the shaft and the hole, and a control surface and a steering engine.
