The invention discloses a leverage of an electrically-controlled measuring instrument on a grinding machine. The leverage comprises a frame, a slider arranged on the frame and a lug plate for clamping a workpiece. The lug plate is fixed on the frame. The slider is provided with a slide groove in which a spiral spring is vertically arranged. A sliding rack is arranged above the slider and provided with a measuring contact in contact with a workpiece. The sliding rack is connected with the slider through a flexible spring. The top of the sliding rack and the top of the slider are provided with a first protrusion and a second protrusion respectively; a gauge is disposed between the first protrusion and the second protrusion; a tapered space is formed below the gauge; a lever is horizontally hinged to the slider; the lever extends into the tapered space; the lever is provided with a first electric contact; a second electric contact is arranged below the first electric contact; the second electric contact is connected with a transverse plate fixed on the slider. By the use of the leverage, the problem that difficulty in controlling grinding degree of the surface of the workpiece during grinding of the surface of the workpiece on the existing grinding machine leads to time and labor waste and low productivity is solved.
