The invention relates to a tug hand-held valve well lid opening and closing device. The device is characterized in that a plurality of supporting legs are vertically arranged at one end of a rod structure of the device, and tugs are arranged at the ends of the supporting legs; and a lifting cantilever frame is arranged on the rod structure, and a lifting hook is connected to the lifting cantileverframe. A well lid is convenient to open and close, labor injuries caused by opening and closing of the well lid of a valve chamber can be completely avoided, the number of personnel for opening and closing the well lid is greatly reduced, and only one person is needed in work. The problem that opening of the well lid is affected due to weather reasons is solved. The device is convenient and flexible to move, and the influence caused by slippery ground is reduced. Compared with the prior art, the well lid is opened quickly in a labor-saving manner.
