The invention provides a meter grabbing mechanical hand for a meter box grabbing robot for an electric meter storage bin. The meter grabbing mechanical hand for the meter box grabbing robot for the electric meter storage bin comprises a mechanical hand connecting piece, a frame connected with the mechanical hand connecting piece and two rotary arm assemblies installed on the two sides of the frame respectively. Each rotary arm assembly comprises a rotary support, a mechanical arm and a grabbing board, wherein each rotary support is fixedly connected with the frame; each mechanical arm is provided with the upper end and the lower end, the upper end of each mechanical arm is hinged to the corresponding rotary support, the rotary plane of each mechanical arm is a vertical plane, and the rotation angle of each mechanical arm is larger than or equal to 90 degrees; and a rotary shaft of each grabbing board is hinged to the lower end of the corresponding mechanical arm. The meter grabbing mechanical hand is simple in structure, the occupied space of the whole robot in the non-grabbing state can be saved by rotating the two mechanical arms face to face in a holding state, the operation space of the whole device is reduced, and more electric meters can be stored in the whole electric meter storage bin.
