Zusammenfassung:	The utility model discloses a bolt cover, which is used for covering a component connecting bolt for mutual connection between two components in an airplane engine. The bolt cover is characterized by being connected to the airplane engine through a cover fixing bolt, and being further provided with a limiting device for operably limiting the cover fixing bolt; the limiting device is operably in a first state or a second state; when the limiting device is in the first state, the cover fixing bolt can be operated; when the limiting device is in a second state, the cover fixing bolt is limited and cannot fall. By applying the bolt cover, the possibility that the cover fixing bolt used for fixing the bolt cover falls can be lowered; moreover, the possibility that the component connecting bolt falls can be correspondingly lowered as well; therefore the safety and the reliability of the engine are further improved.
