US Patent 11175121 Lever indicator

The lever indicator includes a housing, a measuring lever, a displacement sensor and a microcontroller. After extending to the interior of the housing, a tail end of the measuring lever synchronously swings with the displacement sensor for measurement. The microcontroller is located in the housing, and amends and calculates a measurement result according to a signal generated by the swinging of the displacement sensor, and a liquid crystal display for displaying the measurement result is further arranged outside the housing. The displacement sensor includes a fixing grid and a moving grid of a sector structure. The fixing grid is fixed inside the housing, and is correspondingly located above the tail end of the measuring lever. The moving grid is fixed onto the tail end of the measuring lever and swings relative to the fixing grid after linked with the measuring lever.
