[0029] A measuring tool for measuring the step height of the front axle according to the present utility model has a working principle that when it works, before measuring the step of the front axle, the threaded connection with the connecting sleeve is released by rotating the protective shell, and then the rubber pad at the inner end of the arc-shaped block is attached to the front axle. After that, the rotating block drives the rotating rod to rotate, thereby driving the first transmission wheel to rotate through the rotating rod. Then, the first transmission wheel drives two groups of second transmission wheels to rotate through the belt, so that the threaded rod connected by threads moves backward, thereby stretching the arc-shaped block backward. Then, the arc-shaped block slides downward to the connection between the front axle and the step. After that, the depth gauge is used to count the height measurement, so that the height of the front axle step can be measured more accurately. Then, when the parts in the chamber need to be repaired and maintained, the cover plate is removed by four groups of second screws. After that, the parts in the chamber can be repaired and maintained. Then, the cover plate can be reinstalled by four groups of second screws.
