In order to solve the technical problem, the utility model discloses a following technical scheme can solve: the utility model provides a brush cutter blade, includes the installation section, is located the cutting section of installation section both sides, respectively is equipped with cutting edge one along the limit on two sections cutting sections, and two cutting edge one are opposite direction and set up, have seted up the mounting hole on the installation section, respectively are equipped with the hypotenuse on two sections cutting sections, and the hypotenuse is kept away from the cutting edge by the cutting section one by one and is leaned the oblique transition to the cutting section and keep away from installation section one side, is equipped with cutting edge two on the hypotenuse.
By adopting the scheme, the first cutting edge can be used for cutting common shrubs, when the large shrubs need to be cut, the direction of the blade is changed, the blade is cut by the bevel edge, the bevel edge has a guiding effect when the bevel edge is used for cutting, the stress is not vertical stress during cutting, and the vibration is smaller when the large shrubs are cut.
Preferably, the two cutting edges are located on the same plane of the blade.
By adopting the scheme, the cutting edge is positioned on the same plane of the blade, so that the cutting edge is convenient to process.
Preferably, the two second cutting edges are both positioned on a plane of the blade away from the cutting edges.
By adopting the scheme, the two cutting edges are positioned on the same plane of the blade, and the two cutting edges are convenient to process.
Preferably, the oblique side is rounded.
By adopting the scheme, the bevel edge is arc-shaped, the arc-shaped guiding effect is optimal, when large shrubs are cut, the brush cutter vibrates less, and the damage of the brush cutter to hands is greatly reduced.
Preferably, the oblique edges are obliquely transited from the cutting section away from the blade to the end of the blade away from the mounting section.
By adopting the scheme, the length of the bevel edge is longer when the bevel edge is inclined to one side of the cutting section away from the installation section, and the efficiency is higher when shrubs are cut.
Preferably, the bevel edge is provided with a saw-toothed section.
By adopting the scheme, the sawtooth section arranged on the bevel edge has higher cutting efficiency when cutting large shrubs.
The utility model discloses owing to adopted above technical scheme, have apparent technological effect: the first cutting edge and the second cutting edge are respectively located on two planes, the processing is more convenient, the first cutting edge can be used for cutting common shrubs, when large shrubs need to be cut, the blade is changed in direction, the bevel edge is used for cutting on one side, the bevel edge is arc-shaped, the arc-shaped guiding effect is optimal, when the bevel edge is used for cutting, the stress direction of the second cutting edge of the blade is not vertical stress when the blade is used for cutting, the vibration of the second cutting edge is smaller when the blade is used for cutting large shrubs, and the injury of the brush cutter to the hands of an operator is greatly reduced.
