The invention provides a hook for opening well lids. The hook comprises a pull rod and a hook cover. A through hole is formed in the hook cover. The pull rod is movably sleeved with the hook cover through the through hole. The pull rod can move up and down relative to the hook cover. A plurality of notches are formed in the opening of the lower end of the hook cover at equal intervals. Hook heads are arranged in the notches respectively and are fixedly connected through a connection ring. A supporting block used for propping the hook heads open is arranged at the tail end of the pull rod. A connection rope is arranged at the upper end of the pull rod. The supporting block is in the shape of a sphere or a cone, and the maximum diameter of the sphere or the cone is larger than the diameter of the through hole of the hook cover. The hook has the beneficial effects that the well lids can be lifted reasonably and effectively through the hook, the situation that since the well lids are not well hooked, the well lids are damaged or fall on feet is avoided, and the hook is very convenient to use, simple in structure, low in manufacturing cost and suitable for various well lids.
