The step of the lower bottom plate 7 is provided with a lower pressing ring 6 in a matching mode, a plurality of stator and rotor punching sheets 4 are sleeved on the wear-resistant supporting strip 9, inner holes of the stator and rotor punching sheets 4 are evenly provided with a circle of inner grooves, groove sample rods 1 are arranged in the inner grooves in a matching mode, and the groove sample rods 1 are attached to two side faces of the inner wall of the inner grooves in a leaning mode to form grooves respectively. The groove sample bar 1 had a surface roughness value of about 0.8.
