The locking piece 50 is screwed on the ferrule 9, and one end of the locking piece 50 passes through the ferrule 9 and abuts on the scale.

Working principle: when stacking the silicon steel sheets of the main stage and below, the parts playing a role in positioning are a limiting support column 7 and a positioning support column 8. The distance between the first sliding piece 5 and the second sliding piece 6 is adjusted according to the width of the silicon steel sheet, and then the heights of the limiting support column 7 and the positioning support column 8 are adjusted according to the overall thickness of the laminated iron core, so that the two connecting parts can position the current-level silicon steel sheet. And repeating the above actions after the stacking of the current-level silicon steel sheets is finished until the stacking of the main level is finished.

When stacking the silicon steel sheets above the main stage, referring to fig. 4, the parts that play a role in positioning are the semi-cylindrical positioning scale 10 and the planar positioning scale 20. At this time, the spacing support column 7 and the positioning support column 8 are blocked by the main grade silicon steel sheet and cannot move in opposite directions, and the semi-cylindrical positioning scale 10 and the plane positioning scale 20 are moved instead, namely, the distance between the semi-cylindrical positioning scale 10 and the plane positioning scale 20 is adjusted according to the width of the current grade silicon steel sheet. As regards the adjustment in height required for positioning the different levels of silicon steel sheets, this is still achieved by the adjustment of the limit support columns 7 and the positioning support columns 8 in the vertical direction.
