Description
Technical Field
The utility model relates to a blade for a handheld grass trimmer, and belongs to the technical field of machinery.
Background
At present, the working principle of the handheld grass trimmer is that a high-speed rotary cutter generates tangential force to cut weeds. In order to improve cutting capability, meanwhile, the blades of the similar grass mowers are made of plastic materials, the blades are in contact with weeds in an interaction manner, the blades are mostly inclined blades, and only a single blade is adopted, after the grass mowers are cut for many times, the blades are extremely easy to abrade, the cross-sectional area of the blades is increased, so that the contact area with the weeds is increased, the stress area is increased, the cutting capability is greatly reduced, when the abrasion amount reaches the upper limit, the blades are damaged, and the working efficiency is greatly reduced.
Disclosure of utility model
The utility model aims at: aiming at the problem that the cutting edge of the existing handheld grass trimmer is not durable, the blade for the handheld grass trimmer is provided, the abrasion phenomenon of the cutting edge is reduced, and the working efficiency is improved.
The blade for the handheld grass trimmer comprises a fixed end, wherein a tapered cutting section is formed by extending outwards along the radial direction of the fixed end, an inclined cutting edge is arranged on the outer edge of the cutting section, and a semicircular notch is further formed in the inclined cutting edge.
Further, the semicircular notches are distributed at intervals to form saw-tooth-shaped notches. Dividing the two sides of the inclined cutting edge by using a semicircular notch rule, and forming a zigzag incision at the rear end part. The serrated incision is close to the inner edge of the cutting section, and forms a double cutting edge with the oblique cutting edge.
The fixed end is a cylindrical hole. The cylindrical holes are two cylindrical holes which are arranged up and down and have different diameters. The cylindrical holes are fixed through cylindrical pins.
The structure avoids the problem of weakening cutting ability caused by the enlarged contact area between the blade and weeds after the sharpening of the guide blade by changing the structural improvement of the blade edge shape on the premise of not reducing the safety performance and not improving the manufacturing cost, greatly prolongs the service life of the blade by combining the serrated edge with the oblique edge, and effectively reduces the period of reducing the cutting ability caused by normal abrasion.
The utility model has the advantages that the conception is ingenious, and the utility model has the following beneficial effects: the abrasion resistance of the cutting edge is improved through the design of the double cutting edge, so that the working efficiency is improved.
Drawings
The utility model is further described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of an embodiment of the present utility model.
Fig. 2 is a partially enlarged schematic view of fig. 1.
Fig. 3 is a schematic view of fig. 1 in a direction a.

Detailed Description
Examples
The structure of the embodiment is shown in fig. 1-4, and the blade for the handheld grass trimmer comprises a fixed end 1, a tapered cutting section 2 is formed by extending outwards along the radial direction of the fixed end 1, an outer edge 2-1 of the cutting section 2 is provided with a bevel cutting edge 3, and a semicircular notch 4 is further formed at the bevel cutting edge 3. The semicircular notches 4 are distributed at intervals to form saw-tooth-shaped notches. The zigzag incision is close to the inner edge 2-2 of the cutting section 2, and forms a double cutting edge with the oblique cutting edge 3. The fixed end 1 is a cylindrical hole. The cylindrical holes are two upper cylindrical holes 1-2 and lower cylindrical holes 1-1 which are arranged up and down and have different diameters. The cylindrical hole is fixed through a cylindrical pin. When the cutter is used, under the condition of normal abrasion, the inclined cutting edge is worn in advance, and the saw-tooth-shaped notch is formed at the worn part due to structural characteristics, so that the cutting capability is improved, and the purpose of prolonging the service life is achieved.
In addition to the embodiments described above, other embodiments of the utility model are possible. All technical schemes formed by equivalent substitution or equivalent transformation fall within the protection scope of the utility model.
