[0024] The terminal reduction assembly 15 is also arranged on the supporting steel plate 14, which is located below the two rows of fixed steel plates 12 and limits the rotation of the fixed steel plate 12.

[0025] On each fixed steel plate 12, a row of reduction auxiliary assemblies 11 are arranged.

[0026] The reduction auxiliary assembly 11 includes a cylindrical cylinder part 2, which has a diameter of 3 cm and a height of 5 cm in this embodiment. A hemispherical friction part 1 is arranged on the top of the cylinder part 2, which has a diameter of 5 cm in this embodiment. In a preferred case, the cylinder part 2 and the friction part 1 are of an integral structure, and the whole forms a "mushroom head" structure and is made of the same material.

[0027] A first sheath 3 and a second sheath 5 are arranged outside the columnar part 2, which are also made of 2mm-thick high-carbon steel.
