The specific embodiment
A kind of novel trapezoidal blade comprises blade body, and said blade body is provided with blade, and said blade comprises straight cutting edge part, it is characterized in that, said blade also comprises wavy cutting edge part, and said wavy cutting edge partly comprises several curved edges; The angle of said curved edge and said blade body is greater than the angle of other parts of said blade and said blade body.
The below combines accompanying drawing and specific embodiment that the utility model is done further description:
Like Fig. 1 and Fig. 2, a kind of novel trapezoidal blade comprises blade body 1, and blade body 1 is provided with blade 11, and blade 11 comprises straight cutting edge part and wavy cutting edge part, and said wavy cutting edge partly comprises several curved edges; The angle of said curved edge and said blade body is greater than the angle of other parts of said blade and said blade body.
Said wavy cutting edge partly comprises the curved edge of some different in width.
In the present embodiment, said wavy cutting edge partly is distributed in the one side of 11 blades.
Said wavy cutting edge partly is distributed in first left part and right part of blade 11; And be positioned at the wavy cutting edge part 111 and the axis symmetry of the wavy cutting edge part 112 that is positioned at right part of left part, be positioned at the ratio that the wavy cutting edge part 111 of left part accounts for whole blade and be no more than 1/2nd along blade body 1.
What they were different with embodiment 1 is, said wavy cutting edge part only is distributed in one side of first of said blade, and its ratio that accounts for whole blade is not less than 1/2nd.
Embodiment 3
Like Fig. 3 and Fig. 4, a kind of novel trapezoidal blade comprises blade body 2, and blade body 2 is provided with blade 22, and blade 22 comprises straight cutting edge part and wavy cutting edge part, and said wavy cutting edge partly comprises several curved edges; The angle of said curved edge and said blade body is greater than the angle of other parts of said blade and said blade body.
