The invention belongs to the technical field of pipeline maintenance devices, and particularly relates to a lever type manhole cover opener. The lever type manhole cover opener comprises an opener, asteel reinforcing rod, a rotating block, a hook, a lever and a lock sleeve, wherein the bottom of the opener is in threaded connection with the steel reinforcing rod, and the bottom of the steel reinforcing rod is in threaded connection with the hook; and the interior of the opener is connected to the lever in an inserted mode, and the inner wall of the circumference of the lever is buckled with the lock sleeve; and a groove channel is integrally formed in the inner wall of the circumference of the opener. According to the lever type manhole cover opener, the steel reinforcing rod with a hookat the lower part of the opener is inserted into a manhole cover hole, then the steel reinforcing rod is rotationally fixed with the circumferential inner wall of the manhole cover hole through hook arc grooves; after the hook below the opener is firmly fixed to a manhole cover, the steel reinforcing rod is to with a limiting frame through the lock sleeve on the lever in an inserted mode; the lever is pressed downwards, and a lever principle is used for applying force to the opener, so that the steel reinforcing rod below the opener is lifted; the opener is convenient to carry and convenient to use, the opening problem of the manhole cover is solved, and manpower and material resources are saved.
