On the basis of the technical scheme, the utility model discloses can also do following improvement.
Further, above-mentioned cutting edge extension is right triangle sheet structure, and its one right-angle side links to each other with the long limit of above-mentioned blade body, and another right-angle side is located the extension line that above-mentioned blade body corresponds the broadside, and the hypotenuse setting of above-mentioned cutting edge along above-mentioned cutting edge extension, its both ends extend to the both ends of the hypotenuse of the above-mentioned cutting edge extension that corresponds respectively.
The beneficial effects of adopting above-mentioned further scheme are that cutting edge extension design and blade are more reasonable, do benefit to effectual grass-mowing operation.
Furthermore, an included angle α is formed between the oblique edge of the blade extending part and the long edge of the blade extending part, and the included angle is not less than 12 degrees and not more than α degrees and not more than 45 degrees.
The beneficial effect who adopts above-mentioned further scheme is that cutting edge extension angle reasonable in design does benefit to effectual grass mowing operation.
Further, the length ratio of the long side to the wide side of the blade body is 4-3: 1, the ratio of the length of the other right-angle side of the blade edge extension part to the width of the blade body is 1: 4-3.
Adopt above-mentioned further scheme's beneficial effect to be that the size of blade body and cutting edge extension size design are more reasonable, and the performance of beating grass is preferred during the assembly use, and the effect is better.
Drawings
FIG. 1 is a schematic view of the structure of the grass trimmer blade of the present invention.
In the drawings, the components represented by the respective reference numerals are listed below:
1. blade body, 11, cutting edge extension, 12, pilot hole.
Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
Example (b): as shown in fig. 1, the blade of the grass trimmer of the present embodiment includes a rectangular blade body 1, wherein two ends of two long sides of the blade body 1 are respectively integrally formed and outwardly protruded with a cutting edge extension portion 11, the cutting edge extension portions 11 are parallel to the blade body 1, the outer edge of each cutting edge extension portion 11 is respectively provided with a cutting edge, the cutting edges of two cutting edge extension portions 11 located on the same diagonal of the blade body 1 are located on the same side of the blade body 1, the cutting edges of two cutting edge extension portions 11 located on the same end of the blade body 1 are located on two sides of the blade body 1, and the middle of the blade body 1 is provided with an assembly hole 12 penetrating through the cutting edge.
With the grass trimmer assembly in-process of use, four cutting edge extension portions 11 begin wearing and tearing from the blade at the grass trimming in-process, use the wearing and tearing back at every turn, carry out polishing of blade according to the wearing and tearing condition of every cutting edge extension portion 11 (blade), even wear out completely after cutting edge extension portion 11 uses for a long time and disappear the back, also can continue to polish out the blade at the both ends on every long limit of blade body 1 along long limit and continue to use, traditional style of calligraphy blade compares, it has designed more blade allowance of polishing, durable, compare traditional grass trimmer blade the utility model discloses a blade use number of times is more, and use cost is lower.
