Specific embodiment
The technical solution of the utility model is further elaborated with reference to the accompanying drawings and examples.
Referring to attached drawing 1 to a kind of attached composite cutting edge crack stab knife shown in fig. 6, including horizontally extending knife face
1, positioned at the blade 2 of crack stab knife two sides, the blade 2 of two sides, which extends forward, is crossed to form point of a knife.Blade 2 include knife edge 21 with
And the blade surface 22 positioned at 21 two sides of knife edge.The side of knife edge 21 has multiple blade surfaces 22, and the other side of knife edge 21 is knife face 1 or tool
There is a blade surface 22 or there are multiple blade surfaces 22.
The slope of the blade surface 22 of the close knife edge 21 of 21 the same side of knife edge is greater than the slope of the blade surface 22 far from knife edge 21.Make
21 two sides of knife edge it is relatively thick, intensity is relatively large.Positioned at the width of the blade surface 22 of the close knife edge of 21 the same side of knife edge
Less than the width of the blade surface 22 far from knife edge 21.It is bigger closer to the slope of the blade surface 22 of knife edge 21, width is about small, this makes sword
The intensity of cutting edge of a knife or a sword 21 is larger, while when being cut using this crack stab knife, 22 resistance of blade surface of 21 two sides of knife edge is relatively small, more
Conducive to being cut into smooth notch.Preferably, the blade 2 positioned at crack stab knife two sides is symmetrical arranged.It is further preferred,
Blade 2 positioned at crack stab knife side is also to be symmetrical arranged.
Embodiment 1:
As shown in Figure 1 and Figure 2, in the present embodiment, the symmetrical setting of blade 2 positioned at the two sides of crack stab knife, knife
Sword 2 includes knife edge 21, and for the side tool of knife edge 21 there are two blade surface 22, the other side of knife edge 21 is knife face 1.In this example, close to sword
The slope range of the blade surface 22 of cutting edge of a knife or a sword 21 be 0.700 to 1.000, far from knife edge 21 blade surface 22 slope range be 0.268 to
0.577.It is 35 degree to 45 degree close to the blade surface 22 of knife edge 21 and the so-called angular range of horizontal plane, the blade surface far from knife edge 21
22 with the so-called angular range of horizontal plane be 15 degree to 30 degree.
When the slope of the blade surface 22 close to knife edge 21 is 0.9325, the slope of the blade surface 22 far from knife edge 21 is 0.5317.
It is 43 degree close to the blade surface 22 of knife edge 21 and the so-called angle of horizontal plane, blade surface 22 and horizontal plane far from knife edge 21 are so-called
Angle is 28 degree.The puncture effect of this crack stab knife is best at this time.
Embodiment 2:
As shown in attached drawing 3 and Fig. 4, in the present embodiment, the symmetrical setting of blade 2 positioned at the two sides of crack stab knife, knife
Sword 2 includes knife edge 21, and for the side tool of knife edge 21 there are two blade surface 22, the other side of knife edge 21 is with a blade surface 22.This example
In, the slope range close to the blade surface 22 of knife edge 21 is 0.700 to 1.000, and the slope range of the blade surface 22 far from knife edge 21 is
0.268 to 0.577.It is 35 degree to 45 degree close to the blade surface 22 of knife edge 21 and the so-called angular range of horizontal plane, far from knife edge
21 blade surface 22 and the so-called angular range of horizontal plane is 15 degree to 30 degree.
When the slope of the blade surface 22 close to knife edge 21 is 0.8391, the slope of the blade surface 22 far from knife edge 21 is 0.3443.
