The invention discloses a movable jack achieving elastic supporting. The movable jack comprises a vertical hydraulic cylinder and a manual hydraulic pump corresponding to the hydraulic cylinder. Two parallel guide rails are arranged on each of the two sides of the hydraulic cylinder in a spaced manner respectively. The guide rails are provided with sliding grooves with downward openings, and the sections of the sliding grooves are in a T shape. Sliding blocks downwards extending are arranged in the sliding grooves respectively, and the sections of the sliding blocks are in a T shape. Springs are arranged in the sliding grooves respectively. Wheel fixing bases are arranged at the bottoms of the sliding blocks respectively, and wheels are arranged at the bottoms of the wheel fixing bases respectively. By means of the manner and the movable jack achieving elastic supporting, the hydraulic cylinder and the manual hydraulic pump are convenient to move through supporting of the wheels, during hoisting, the bottoms of the wheels gradually ascend to be kept flush with the bottom of the hydraulic cylinder, the bottom of the hydraulic cylinder is grounded, the supporting stability of the hydraulic cylinder is improved, operation is convenient, and operation safety is improved.
