The cavity that described clamping is recessed and the axial cross section of clamping part are the tapering conical surface identical and that shrink to described cover handle tail, and 0.5 °≤γ≤30 ° of span of conical surface drift angle γ.
Between described cutting portion and clamping part, be provided with stage portion, when described cutting part is in place on described instrument toggle, between described end face and described stage portion, have apart from d, and 0 < d≤0.1mm.
A kind of dismantled and assembled rotary cutter, comprise instrument toggle and be arranged on the cutting part on described instrument toggle, described instrument toggle comprises cover negative winding stem and cover handle tail, described cutting part comprises cutting portion and clamping part, described clamping part is connected by multiple thread with described cover negative winding stem, and the angle between each adjacent thread line of described multiple thread is unequal.
The difference of the angle between each adjacent thread line of described multiple thread is Δ X, and 2 °≤Δ X≤15 °.
Compared with prior art, the invention has the advantages that:
Dismantled and assembled rotary cutter of the present invention comprises instrument toggle and is arranged on the cutting part on instrument toggle, instrument toggle comprises cover negative winding stem and cover handle tail, cutting part comprises cutting portion and clamping part, clamping part is connected by multiple thread with cover negative winding stem, multiple-threaded each threaded line has different section configurations, guarantee that cutting part can only be installed on instrument toggle by single mode, only need cutting part corresponding with the screw thread on instrument toggle, just can be quick, accurately complete the installation of cutting part, before there will not be installation, can not accurately locate the problem that causes completing fast installation.
Dismantled and assembled rotary cutter of the present invention comprises instrument toggle and is arranged on the cutting part on instrument toggle, instrument toggle comprises cover negative winding stem and cover handle tail, cutting part comprises cutting portion and clamping part, clamping part is connected by multiple thread with cover negative winding stem, angle between each adjacent thread line of multiple thread is unequal, therefore cutting part and instrument toggle only have a kind of alignment clamping part correctly can be screwed into cover negative winding stem, thereby can be fast, accurately complete the installation of cutting part, before there will not be installation, can not accurately locate the problem that causes completing fast installation.

The specific embodiment
Below with reference to Figure of description and specific embodiment, the present invention is described in further details.
Fig. 1 to 4 shows the first embodiment of dismantled and assembled rotary cutter of the present invention, this dismantled and assembled rotary cutter comprises instrument toggle 1 and is arranged on the cutting part 2 on instrument toggle 1, instrument toggle 1 comprises cover negative winding stem 11 and cover handle tail 12, cutting part 2 comprises cutting portion 21 and clamping part 24, clamping part 24 is connected by multiple thread 3 with cover negative winding stem 11, each threaded line of multiple thread 3 has different section configurations, thereby guarantee that cutting part 2 can only be installed on instrument toggle 1 by single mode, only need cutting part 2 corresponding with the screw thread on instrument toggle 1, just can be quick, accurately complete the installation of cutting part 2, there will not be and can not accurately locate that cause cannot be quick before installation, correctly complete the problem of installation.
In the present embodiment, it is recessed 14 that the end face 13 of cover negative winding stem 11 is provided with clamping, and clamping part 24 is set in clamping recessed 14.
In the present embodiment, cutting part 2 also comprises the handling moment of torsion face 22 of being convenient to handling instrument clamping cutting part 2, and handling moment of torsion face 22 is arranged on cutting portion 21 near one end of clamping part 24, and handling instrument easy to use carries out clamping to cutting part 2.
The axial cross section that clamps recessed 14 cavity and clamping part 24 is the tapering conical surface identical and that shrink to cover handle tail 12, and 0.5 °≤γ≤30 ° of span of conical surface drift angle γ, by clamp recessed 14 and clamping part 24 in axial location, improve cutting part 2 and be arranged on the axial carrying capacity on instrument toggle 1, in the present embodiment, γ=10 °.
