Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0021] Refer to the attached drawings of the specification Figures 1-3 As shown, this technical solution provides a multi-functional lawn mower blade, including a tool holder 1, a blade 2 and a trimming line 3. The tool holder 1 is provided with a rotating shaft connection hole 11. The blade 2 is connected to the tool holder 1. The blade 2 is provided with a plurality of cutting edges 23, and the orientations of the cutting edges 23 are all clockwise. One end of the trimming line 3 is connected to the tool holder 1, and the other end of the trimming line 3 extends outwards. When the blade provided by the present utility model works, it rotates counterclockwise. When normally trimming grass, the trimming line 3 works and the blade 2 does not contact the grass. When encountering a shrub, the material of the trimming line is a nylon rope, and it will bend backwards. The blade 2 works to cut off the shrub, so that grass and shrubs can be cut simultaneously without stopping the machine, improving the working efficiency of the lawn mower and meeting various usage scenarios.

[0022] As a preferred implementation manner of this embodiment, the blade 2 is provided with a first fixing hole 21 and a second fixing hole 22. The rotating shaft connection hole 11 protrudes to one side to form an annular convex block 12. The blade 2 is fixed to the tool holder 1 through the second fixing hole 22 by matching with a fixing bolt 14, and the annular convex block 12 is located in the first fixing hole 21.

[0023] Specifically, the shape of the second fixing hole 22 is "racetrack-shaped", so that the blade can be installed on tool holders of different specifications.

[0024] As another preferred implementation manner of this embodiment, the tool holder 1 is provided with a trimming line slot 13. One end of the trimming line 3 is provided with a trimming line limiting block 31. The trimming line 3 passes through the trimming line slot 13, and the trimming line limiting block 31 is located on one side of the trimming line slot 13. The trimming line 3 is located between the blade 2 and the tool holder 1, and the trimming line limiting block 31 fixes one end of the trimming line 3 to the tool holder 1.

[0025] Specifically, the material of the trimming line 3 is nylon.

[0026] In addition, the material of the tool holder 1 is aluminum alloy.

[0027] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0028] This technical solution provides a multifunctional lawn mower blade, which includes a tool rest, a blade, and a trimming line. The tool rest is provided with a rotating shaft connection hole. The blade is connected to the tool rest. The blade is provided with a plurality of cutting edges, and the orientations of the cutting edges are all clockwise.
