The invention provides a lifting tool for a ship cabin cleaning machine. The lifting tool comprises a lifting tool supporting piece and a hoisting piece, wherein the lifting tool supporting piece is provided with a first limiting assembly and at least one set of second limiting assembly. The first limiting assembly comprises two first limiting pieces, and the two first limiting pieces are arrangedin a spaced manner and are symmetrically fixed on the lifting tool supporting piece; each second limiting assembly comprises two second limiting pieces, and the two second limiting pieces are symmetrically arranged and detachably connected with the lifting tool supporting piece; the hoisting piece is slidably arranged on the lifting tool supporting piece section between the first limiting piece and the end part of the lifting tool supporting piece, and the second limiting pieces are arranged on the portions, between the end part of the lifting tool supporting piece and the first limiting piece, of the lifting tool supporting piece; and one end of the hoisting piece is connected with a crane grab bucket through a flexible piece, and one end of the hoisting piece is mechanically connected with a cabin cleaning machine through a flexible piece. By means of the lifting tool, the problem that in the prior art, the universality of the ship cabin cleaning machine is poor due to the fact thatthe ship cabin cleaning machine can only be connected through the lifting tool matched thereof is solved.
