[0002] The main function of a manhole cover is to protect the wellhead or pipe opening to prevent people and objects from falling in. It can also prevent foreign matter from entering the pipeline and maintain the safety and smooth flow of the pipeline. However, there are still many defects in manhole covers in actual use.

[0003] A manhole cover that is convenient for maintenance and has application number CN201620594549.2 discloses that a user can quickly and efficiently remove the manhole cover when maintenance is needed, thereby making the maintenance more efficient.

[0004] However, the above-mentioned manhole covers are relatively cumbersome to open during actual maintenance. Workers will feel very tired when opening multiple manhole covers continuously, resulting in a decrease in the speed of opening subsequent manhole covers for maintenance, thereby increasing the time for workers to open and maintain sewer pipes and reducing maintenance efficiency. Therefore, in view of the above situation, the utility model proposes a new solution. Utility Model Content
