The invention discloses a fine adjustment base for a jack. The fine adjustment base comprises a socket, a mounting frame and a connecting rod, wherein the top of an upper base and the socket are integrally formed; a shock pad is arranged on the upper surface of the upper base; an empty groove is formed in the middle of the bottom of the upper base; a bearing is mounted in the empty groove in the bottom of the upper base; the bottom of a shaft rod is connected with the upper surface of a lower base; an upper handle and a lower handle are mounted on the right side of the upper base and the rightside of the lower base correspondingly; the upper handle and the lower handle make contact with each other but are not connected with each other; trundles are mounted at the bottom of the lower base;the front sides and the rear sides of the trundles are connected with the mounting frame; a hanging plate is mounted on the surface of the bottom of the lower base; a fixing plate is connected to thelower portion of the middle of the hanging plate; an empty groove is formed in the fixing plate; and the connecting rod is mounted in the empty groove of the fixing plate. According to the fine adjustment base for the jack, the upper base and the lower base are arranged to be of a mutual rotation structure under the action of the shaft rod and the bearing, and thus rotation can be achieved conveniently under the condition that the upper portion of the jack is fixed.
