[0008] In at least some embodiments, the damage prevention force-bearing part further includes: connecting screws and movable blocks; there are two connecting screws, and the two connecting screws are inserted into the damage prevention force-bearing block b, and the two connecting screws are also threadedly connected to the damage prevention force-bearing block a; there are two movable blocks, and the two movable blocks are slidably installed in the damage prevention force-bearing block a and the damage prevention force-bearing block b.

[0009] In at least some embodiments, the outer ends of the two movable blocks are hemispherical structures, and the outer ends of the two movable blocks are inserted into arc-shaped slots.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

[0018] Furthermore, when the two connecting rings b are connected to another stator lamination body, the four movable blocks can automatically slide inward, causing the four movable blocks to automatically separate from the two arc-shaped slots. When the two adjacent stator lamination bodies are not deformed, when the two detection wires are pressed with a tool, the two connecting rings b can be smoothly pushed out by the two sets of anti-damage force-bearing parts. When the two adjacent stator lamination bodies are deformed, when the two detection wires are pressed with a tool, the two detection wires will deform, causing the two detection wires to separate from the two mounting grooves. At this time, the two adjacent stator lamination bodies cannot be assembled in place, making it easy to remove the deformed stator lamination body. Attached Figure Description

[0038] In this embodiment of the disclosure, such as Figure 6 and Figure 8As shown, the connection detection unit 300 includes: a connecting ring a301 and a connecting ring b302; the connecting ring a301 is fixedly installed in the mounting hole 101; the connecting ring b302 is threadedly connected to the connecting ring a301; the bottom of the connecting ring a301 is flush with the bottom of the stator lamination body 100, and the distance from the bottom of the connecting ring a301 to the top of the connecting ring b302 is twice the thickness of the stator lamination body 100, and the connecting ring a301... The outer ends of the connecting ring b302 are respectively provided with chamfers; a rectangular rotating groove 3021 is formed on the outer wall of the connecting ring b302, and two mounting grooves 3022 are formed on the inner wall of the connecting ring b302; the connecting detection part 300 also includes: a detection wire 303; the detection wire 303 is slidably installed in the two mounting grooves 3022, and the bending resistance of the detection wire 303 is greater than the resistance between the two movable blocks 204 and the arc-shaped groove 102;

[0039] Its specific function is as follows: Since the connecting ring a301 is fixedly installed in the mounting hole 101, and the bottom of the connecting ring a301 is flush with the bottom of the stator lamination body 100, and the distance from the bottom of the connecting ring a301 to the top of the connecting ring b302 is twice the thickness of the stator lamination body 100, when the two connecting rings b302 are connected to another stator lamination body 100, the two connecting rings b302 can be inserted into the two sets of anti-damage force-bearing parts 200 on the other stator lamination body 100, realizing the automatic separation of the two sets of anti-damage force-bearing parts 200 from the stator lamination body 100, and realizing the cyclic use of the anti-damage force-bearing parts 200; and since the connecting ring b302 is threaded onto the connecting ring a301, and a rectangular rotating groove 3021 is opened on the outer wall of the connecting ring b302, when the lamination body 100 is assembled, the workers can unscrew the two outermost connecting rings b302.

[0040] Furthermore, since the two support springs 205 are installed inside the anti-damage force-bearing blocks a201 and b202, and the two support springs 205 are also connected to the inner ends of the two movable locking blocks 204, when the two connecting rings b302 are connected to another stator lamination body 100, the four movable locking blocks 204 can automatically slide inward, causing the four movable locking blocks 204 to automatically separate from the two arc-shaped locking grooves 102; also, since the inner wall of the connecting ring b302 is provided with two mounting grooves 3022, and the detection wire 303 is slidably installed in the two mounting grooves 3022, and the bending resistance of the detection wire 303 is greater than that of the two...

[0041] The specific usage and function of this embodiment are as follows:

[0042] When using this invention, the operator first installs two sets of anti-damage force-bearing parts 200 and two sets of connection detection parts 300 into the four mounting holes 101.

[0043] Then, using tools and two detection wires 303, another stator lamination body 100 is moved. When the two connecting rings b302 are connected to the other stator lamination body 100, the two connecting rings b302 can be inserted into the two sets of anti-damage force-bearing parts 200 on the other stator lamination body 100, realizing the automatic separation of the two sets of anti-damage force-bearing parts 200 from the stator lamination body 100, and realizing the cyclic use of the anti-damage force-bearing parts 200; when the two connecting rings b302 are connected to the other stator lamination body 100, the four movable blocks 204 can automatically slide inward, so that the four movable blocks 204 automatically separate from the two arc-shaped slots 102; when adjacent When the two stator lamination bodies 100 are not deformed, when the two detection wires 303 are pressed with a tool, the two connecting rings b302 can be smoothly pushed out of the two sets of anti-damage force-bearing parts 200. When the two adjacent stator lamination bodies 100 are deformed, when the two detection wires 303 are pressed with a tool, the two detection wires 303 will deform, causing the two detection wires 303 to separate from the two mounting grooves 3022. At this time, the two adjacent stator lamination bodies 100 cannot be assembled in place, making it easy to remove the deformed stator lamination bodies 100. When the lamination bodies 100 are assembled, the workers can unscrew the two outermost connecting rings b302.
