Gauging rule for fine adjustment of track and shifting method of gauging rule

The invention relates to the technical field of track fine adjustment, in particular to a gauging rule for track fine adjustment and a shifting method of the gauging rule. The ruler further comprises moving seats, spring pieces, magnetic wheels and a motor. The moving seats are arranged on the sides of the two ends of the ruler body respectively. One magnetic wheel is rotationally arranged at the bottom of each moving seat, and the magnetic wheels and the steel rails are magnetically attracted; one motor is fixedly arranged at the side part of each moving seat, and the motors are used for driving the magnetic wheels to roll on the steel rail, so that the moving seats push or pull the ruler body to move on the steel rail; the motor is arranged to drive the magnetic wheel to roll on the steel rail, so that the movable seat pushes or drags the ruler body to move on the steel rail, automatic displacement of the ruler body is achieved, the labor intensity of measuring personnel is reduced, and the efficiency of fi
