One solution for the centering element n.22 is a bearing, a shoulder n.213 is arranged on the receiving channel n.210 near the head end n.211, and the centering element n.22 abuts against the shoulder n.213. In one scheme, the shoulder n.213 faces to the side of the head end (lower end) n.211 of the receiving channel n.210, and the centering element n.22 is installed into the shoulder n.213 from the head end n.211 of the receiving channel n.210. When the blade n.4 is installed, the blade n.4 is installed from the side of the head end n.211 of the receiving channel n.210, and a clearance fit is formed between the blade n.4 and the inner diameter of the centering element n.22. A hole n.212 is formed in the upper end of the containing channel n.210, and the push rod n.24 penetrates out of the cutter sleeve n.21 from the hole n.212; and a limiting edge n.2121 is also arranged between the edge of the shaft hole n.212 and the inner wall of the containing channel n.210.

Referring to fig. 13 and 16, in one scheme, an inner limiting step portion is arranged at the lower portion of a housing inner cavity n.10 of a cutter housing n.1, an outer limiting step portion is arranged at the lower portion of the outer side of a cutter sleeve n.21, and when a blade fixing member n.2 moves to the maximum position relative to the cutter housing n.1, the outer limiting step portion abuts against the inner limiting step portion.
