[0029] 2. The driving member drives the push block to move vertically. When the push block moves downward, it drives the slider to move away from the axis of the stator seat and abuts against the stator to lock the stator. When the push block moves upward, the moving block drives the slider to move toward the axis of the stator seat, thereby releasing the stator position limit and locking the stator position is simple and convenient.

The piston rod 16 moves downward to drive the push block 414 to move downward, and the push block 414 then drives the slider 413 to move the slider 413 away from the axis of the stator seat 2 until the extrusion bar 41312 and the reinforcement block 415 abut against the flat wire group 5.

While the fold line structure 3 rotates, the driving mechanism drives the first fold line component 31, the second fold line component 32, the third fold line component 33 and the fourth fold line component 34 to move upward respectively.

[0069] After the shaping of the flat wire group 5 is completed, the piston rod 16 moves upward, driving the slider 413 to move toward the axis of the stator seat 2, so that the extrusion strip 41312 and the reinforcement block 415 are separated from the flat wire group 5, and then the stator is directly taken out.
