The long rod 26 drives the top rod 28 to rotate inward. Through the cooperation of the long rod 26 and the top rod 28, the lamination 1 is protected from collision with external uncertain factors after placement, which enhances the structural stability and reliability of the motor rotor lamination 1 and protects the lamination 1 from accidental damage.
[0028] In use, the automatic 360-degree rotation structure of the motor blade of this utility model involves inserting the stacked blades 1 of the motor rotor into the central rod 22, and then inserting the stacked blades 1 of the motor rotor into the positioning rod 23 on the chassis 21 through the positioning holes.

[0029] When the lamination 1 moves to the bottom, the bottom surface of the lamination 1 will contact the abutment rod 27, causing the abutment rod 27 to drive the long rod 26 to rotate inward on the outer wall of the rotating shaft 25. The long rod 26 drives the top rod 28 to rotate inward. Through the cooperation of the long rod 26 and the top rod 28, the lamination 1 is protected from collisions with external uncertainties after placement, which enhances the structural stability and reliability of the motor rotor lamination 1 and protects the lamination 1 from accidental damage.
[0030] Example 2
[0031] like Figure 5 As shown, the fixing device 3 includes a hollow column 31, a slip ring 32, a sliding column 33, a slot 34, a C-shaped locking plate 35, an abutment plate 36, and a spring piece 37. The hollow column 31 is installed on the top of the top rod 28 near the center rod 22, and the hollow column 31 and the top of the top rod 28 near the center rod 22 are fixedly connected. The slip ring 32 is slidably installed on the inner wall of the hollow column 31, and the sliding column 33 is installed on the inner wall of the slip ring 32. The inner wall of the sliding column 33 and the inner wall of the slip ring 32 are... A fixed connection is established, with a slot 34 formed on the outer wall of the bottom end of the sliding column 33.

The top of the C-shaped clamping plate 35 slides out of the slot 34 on the sliding column 33, causing the sliding column 33 to drive the slip ring 32 to slide down. The sliding column 33 thus connects the positioning rod 23's locking hole to it as a whole. Through the setting of the sliding column 33, it is ensured that the stacked plate 1 will not be displaced or loosened during transportation, thereby improving the stability and safety of the entire structure and reducing the problem of wear of the stacked plate 1 caused by vibration and other reasons.
