[0044] ​The moving magnetic thickness block 7 is movably connected inside the circular cutter body 1, and the side close to the fixed magnetic thickness block 6 and the first cutter die 4 is in contact with the fixed magnetic thickness block 6 and the first cutter die 4 respectively.

[0045] The rotating mechanism 2 is movably connected inside the circular cutter body 1, and the side close to the moving magnetic thickness block 7 is fixedly connected with the moving magnetic thickness block 7. The rotating mechanism 2 is used for rotating the moving magnetic thickness block 7.

[0053] In the example, the surface of the circular cutter body 1 is provided with through holes 11 matched with the first cutter die 4 and the second cutter die 5. The through holes 11 can facilitate the first cutter die 4 and the second cutter die 5 to enter and exit the inside of the circular cutter body 1.
