The invention discloses a lifting tool for multi-station machining of a household appliance display screen outer shell. The lifting tool comprises a base, two supporting columns are symmetrically welded on the two sides of the base, moreover, two threaded supports are fixedly welded to the upper ends and the lower ends of the two supporting columns in a symmetrical mode respectively, and the upperthreaded support and the lower threaded support are in threaded connection with rolling shaft screw rods; and a double-shaft motor is installed at the middle end of the base, moreover, the output ends of the double-shaft motor are connected with first-stage bevel gears correspondingly, the first-stage bevel gears are meshed with second-stage bevel gears, the rolling shaft screw rods are in threaded connection with rolling shaft nuts, moreover, sliding sleeves are welded on the rolling shaft nuts, and the sliding sleeves sleeve the supporting columns in a sliding mode. According to the tool, an operation desk is moved up and down to achieve vertical movement of the display screen outer shell, and fixing, drilling, disassembling and assembling are carried out conveniently on the display screen outer shell; and a tight clamping device is used for limiting the position of the display screen outer shell in the horizontal direction, and moreover, multi-position drilling machining can be carried out on the display screen outer shell through a movable drill bit so that the drilling efficiency of the display screen outer shell can be improved.
