When a machine platform is installed or maintained, a plurality of screws are required to be screwed in a workpiece plane, in order to enable the stress of a workpiece to be uniform and ensure the flatness of the workpiece, an operator can firstly screw all the screws by hands according to a star-type screwing method (namely under the condition that a plurality of screws exist in the workpiece plane, the screws can be screwed according to a diagonal principle and can be screwed in sequence according to a certain sequence, so that connecting lines among the successively screwed screws form a star-type track (for example, when 5 screws are uniformly distributed along a circle, 5 screws can be numbered in a clockwise direction to be 1-5, the screws can be screwed one by one according to the sequence of 1-4-2-5-3, and the connecting lines among the successively screwed screws can form a five-pointed star)), and then the screws are preliminarily fixed by using a torque wrench according to the star-type screwing method.
