Cabin opening driving mechanism limiting device and cabin opening driving mechanism

The utility model relates to a limiting device of a cabin opening driving mechanism. The driving mechanism comprises a limiting structure, the limiting structure is provided with a limiting body, a first hook part and a second hook part extend outwards from the limiting body to form a first containing space and a second containing space, and a moving space allowing the driving mechanism to penetrate through is formed between the first hook part and the second hook part; and the supporting structure is arranged on the fixing structure and used for supporting the limiting structure. According tothe limiting device for the cabin opening driving mechanism, when the cabin opening driving mechanism uses high-impact working media such as explosion fuel gas as the working media of the driving mechanism for emergency unlocking, the cabin opening driving mechanism can be prevented from being damaged; excessive requirements on conditions such as structural strength, rigidity and manufacturing precision of a peripheral s
