A first connecting rod 1005 and a second connecting rod 1006, which are parallel to each other, are hinged on the rounding seat block 1004. The second link 1006 and the third link 1007 also include a fourth link 1008 and a fifth link 1009 that are hinged to the first link, the second link and the third link. The fifth link 1009 is parallel to the fourth link 1008. An extension rod 1010 is provided on the fifth link 1009. The drive wheel 1003 is rotatably connected to the extension rod 1010. A segmented iron core clamping fixture 1011 is provided on the first link 1005.

Each time, four cores enter the core positioning fixture 6 to prevent mutual interference.

[0025] The principle of switching and lifting between the upper circular retaining ring 7, the middle circular retaining ring 8, and the lower circular retaining ring 9 is as follows: Through gear ring transmission, the operating adjustment plate 1107 is rotated to select the corresponding push rod, so that the other push rods can pass through.
