The invention relates to a well opener, and relates to the technical field of pipeline maintenance devices, in order to solve the problem that a well cover falls off and hits constructors due to the fact that a well hook is prone to being separated from a well cover bayonet, the well opener comprises a force holding rod, a supporting rod is rotationally connected to the force holding rod, and a lifting rod is rotationally connected to the end of the force holding rod; the lifting rod is parallel to the rotating axis of the supporting rod, a lifting assembly used for lifting the well lid is arranged at the end, away from the force holding rod, of the lifting rod and comprises two hinged abutting plates, and an adjusting piece is arranged in the force holding rod and used for controlling the included angle between the two abutting plates. The two abutting plates can be drilled into a manhole cover bayonet and abut against the inner wall of a manhole cover, and a control piece used for controlling the adjusting piece is arranged at the end, away from the lifting rod, of the force holding rod. The well lid lifting device has the effect that the situation that the well lid falls off to hurt people in the lifting process is reduced.
