Abstract

A portable jack comprises a jack body, two connection assemblies, an installing bottom plate and a top cover. The bottom of the jack body is connected to the installing bottom plate. The installing bottom plate is located between the two connection assemblies. One side of one of the two connection assemblies is hinged to one side of the installing bottom plate, and one side of the other connection assembly is hinged to the other side of the installing bottom plate. The side, far away from the installing bottom plate, of one connection assembly is hinged to one side of the top cover. The other side of the top cover is detachably connected with the side, far away from the bottom plate, of the other connection assembly through a connection piece. The two connection assemblies, the installing bottom plate and the top cover are used for defining a storage space which is used for storing the jack body. A lifting handle is arranged on the outer side of the top cover. According to the portable jack, the two connection assemblies, the installing bottom plate and the top cover form the storage space where the jack body is stored, and accordingly portability of the jack is achieved; and meanwhile the installing bottom plate is used as a force exerting face of a supporting platform of the jack so that the force exerting process can be more stable.
