[0025] As a technical optimization solution of the present invention, by setting an adjustment mechanism 9, the positioning rod group 7 can be adjusted and moved, avoiding the position of the positioning rod group 7 being fixed, which causes the positioning rod group 7 to only have an effect on one type of rotor punching, thereby improving the adaptability of the positioning rod group 7 to multiple types of rotor punchings.

[0026] refer to Figure 6 A torsion block 10 is fixedly connected to the interior of the knob 6 and is located at the bottom of the lower pressure plate 1 .

[0027] As a technical optimization solution of the present invention, by providing the twist block 10, it is possible to facilitate the user to rotate the knob 6, thereby preventing the knob 6 from being difficult to be pinched by the user, resulting in the knob 6 being difficult to rotate, and improving the rotation efficiency of the knob 6.

[0036] After the rotor sheet group 4 is stacked, the upper and lower pressure plates 1 and 3 are pressed together, and the upper and lower pressure plates 3 are pressed together, so that the rotor sheet group 4 is in a stacked state. When other types of rotor sheet groups 4 need to be stacked, the knob 6 is rotated according to the holes on the surface of the rotor sheet group 4. The knob 6 drives the rotating seat 5 and the positioning rod group 7 to rotate, and the angle of the positioning rod group 7 is adjusted to the position corresponding to the holes on the surface of the rotor sheet group, and the motor 93 is started. The motor 93 drives the pulley 94, the transmission belt 95 and the bidirectional screw 91 to rotate, and the bidirectional screw 91 drives the moving block 92 and the positioning rod group 7 to adjust the spacing, and the redundant positioning rod group 7 can be removed from the inside of the moving block 92, so that the number of positioning rod groups 7 corresponds to the number of holes on the surface of the rotor sheet group 4, and the rotor sheet group 4 is sleeved on the surface of the shaft core 2 and the positioning rod group 7.
