Supporting mechanism for handheld electric energy meter calibrator

A supporting mechanism for a handheld electric energy meter calibrator comprises a calibrator body which is suspended at the lower part of an electric meter box through the supporting mechanism. The supporting mechanism comprises a transversely-arranged suspension supporting plate, one end of the suspension supporting plate is in clamping connection with the bottom wall of the electric meter box through a clamping assembly, the other end of the suspension supporting plate is in longitudinal lifting connection with a supporting square rod through a positioning assembly, and the top of the supporting square rod is horizontally and rotationally connected with a clamping and supporting assembly through a rotating assembly. The calibration instrument body is transversely and detachably clamped in the clamping and supporting assembly. The supporting mechanism is simple in structure and convenient to carry, and the supporting mechanism can fixedly suspend the calibrator body on the bottom wall of the electric meter
