Be not limited to above-mentioned embodiment, it is also possible to select plane mode, the first axial end of the i.e. first sleeve 12 and
The end face of the first axial end of the second sleeve 13 is plane, relies on the tensile force of spring to make the first sleeve 12
With the frictional force that second between sleeve 13 increases.Or, the first axial end of the first sleeve 12 is conehead,
First axial end of the second sleeve 13 is set to taper hole, by coordinating of conehead and taper hole, is not only axially obtaining
Obtained friction force, and both circumferences can also obtain friction force.Both modes are not owing to having picture
Domatic such obstruction in above-mentioned embodiment, therefore, during actual chaffcutter, the second cutter shaft exists
In the case of stress, it is possible to can rotate and (if the tension force of spring is sufficiently large, make the first sleeve and
Frictional force between two sleeves is very big, the most also will not rotate), but due to the first sleeve and second
The frictional force existed between sleeve, the rotating speed of the second cutter shaft is far below the rotating speed of the first cutter shaft, therefore so that
There is speed degree between 3rd cutting knife 6 and the first cutting knife 4 and the second cutting knife 5, material can be cut off in the same old way.
Such cooperation occurs to rotate when chaffcutter, therefore owing to making the second cutter shaft, it is to avoid the blocking of material.
Above-mentioned first sleeve 12 and the second sleeve 13 can also use other irregular cooperation faces to join
Close (such as curved surface).
The foregoing is only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention, all
The equivalent structure utilizing description of the invention and accompanying drawing content to be made or equivalence flow process conversion, or directly or
Connect and be used in other relevant technical fields, be the most in like manner included in the scope of patent protection of the present invention.
