[0002] In the prior art, a protective cover is usually arranged on a lifting device to separate the inside and outside of the lifting device, and the protective cover is flexible to achieve the effects of dustproof, waterproof or protection. The existing lifting device comprises a fixed end, a driving mechanism and a movable end, the movable end can be driven by the driving mechanism to approach or move away from the fixed end, thereby completing the lifting action, and the protective cover is arranged between the movable end and the fixed end.

[0003] Although the existing protective cover can separate the inside and outside of the driving mechanism, some problems still exist in the use process. First, when the movable end of the lifting device moves away from the fixed end, the protective cover is in an unfolded state, and when the movable end of the lifting device approaches the fixed end, the two ends of the protective cover will approach each other. Since the protective cover is flexible, wrinkles will be formed in the middle part of the protective cover. The length of the free end of the wrinkles is difficult to estimate, and the wrinkles are easy to interfere with the operation of the driving mechanism or other transmission structures inside the device, thereby causing damage to the device or safety accidents. Secondly, a plurality of connection points are arranged at the two ends of the protective cover to fix the protective cover on the movable end and the fixed end of the lifting device. Stress is concentrated at the connection points of the protective cover and the lifting device, which is easy to damage, and the protective cover is easy to be stretched and deformed. SUMMARY
