Stator framework assembly capable of preventing deformation of pole claw and stepping motor comprising stator framework assembly

The invention provides a stator framework assembly capable of preventing deformation of a pole claw and a stepping motor comprising the stator framework assembly. The stator framework assembly comprises a first pole plate, a second pole plate and a framework. The first pole plate comprises an annular first plate-shaped body and a plurality of first pole claws integrated with the first plate-shaped body, and the plurality of first pole claws are bent from the first plate-shaped body and extend in the axial direction. The second pole plate comprises an annular second plate-shaped body and a plurality of second pole claws integrated with the second plate-shaped body, and the plurality of second pole claws are bent from the second plate-shaped body and extend in the axial direction. And the first skeleton part, the first polar plate, the second polar plate and the second skeleton part are stacked in sequence to form a rotor cavity. The framework further comprises a middle framework part which is connected between
