description The invention discloses a two-degree-of-freedom portable jack, and belongs to the field of mechanical equipment. The jack comprises a base assembly, a translation assembly and a lifting assembly, wherein the base assembly comprises load bearing wheels, steering wheels, a base supporting frame and a vertical base mounting plate; due to arrangement of the base assembly, free movement of the jack onthe ground can be realized; the translation assembly comprises a hand wheel, a sprocket, a chain, a linear guide rail pair, a supporting plate and a lead screw pair, and due to arrangement of the translation assembly, horizontal translation of the jack can be realized; and the lifting assembly comprises a support column, a support arm, a jack, a telescopic arm and a lifting hook, and can be used for lifting up and move heavy objects. The two-degree-of-freedom portable jack disclosed by the invention has degrees of freedoms which are located in the directions of up-down movement and horizontaltranslation, and has the a
