The invention discloses a lifting tool. The lifting tool comprises a sleeve assembly, a driving assembly and a clamping piece; the sleeve assembly comprises a sleeve, a lifting and lowering rod and asupporting piece; a notch is formed in the wall of the sleeve; the lifting and lowering rod is arranged in the sleeve, and a plurality of protrusions are arranged on the outer surface of the lifting and lowering rod; the supporting piece is connected with the outer surface of the sleeve and used for supporting a cylindrical target; the driving assembly is arranged on the outer side of the sleeve and comprises a shaft and a gear; the shaft is rotatably connected with the sleeve, and the gear is fixedly arranged on the shaft in a sleeving mode and located at the notch of the sleeve and meshes with the protrusions of the outer wall of the lifting and lowering rod; and the clamping piece is connected with the outer wall of the sleeve. According to the lifting tool, the influence of gravity canbe overcome, installation and detaching of the cylindrical target can be conveniently finished with one person by a method of screwing a thread after lifting, compared with a traditional double-people installing method, the labor is saved, and meanwhile, the reliability of installation and the convenience of detaching are further improved.
