Description

Technical Field

[0001] The present application relates to the technical field of gardening tools, and in particular to a trimmer blade. Background Art

[0002] When mowing lawns or plants, there may be different requirements for mowing at different angles, such as horizontal mowing, angled mowing or vertical mowing, so a trimmer is used, and the trimmer blade is an important part of the trimmer. The trimmer blade is generally provided with a mounting hole, and the motor shaft in the trimmer can pass through the mounting hole so that the trimmer blade can be installed on the trimmer. The motor in the trimmer will drive the blade to rotate at high speed, thereby trimming the lawn or plants.

[0003] Sometimes there are multiple types of vegetation planted, and during the pruning process, only one type of vegetation may be pruned. The length of the trimmer blade determines the diameter range of the trimmer, so according to the different pruning diameter ranges, the staff needs to carry multiple blades of different lengths. However, since the trimmer blade is sharp and the staff needs to move during the pruning process, it is inconvenient to carry multiple blades to meet the needs of pruning vegetation of different diameter ranges. Utility Model Content

[0004] In order to enable a trimmer blade to meet the effect of trimming vegetation within multiple different diameter ranges, the present application provides a trimmer blade.

[0005] The present application provides a trimming machine blade, which adopts the following technical solution:

[0006] A trimmer blade comprises a blade body, wherein the blade body is provided with a plurality of mounting holes which can be connected to the trimmer, the plurality of mounting holes are arranged at intervals along the extension direction of the blade body, and the blade body is provided with a reinforcement strip, the extension direction of the reinforcement strip is consistent with the extension direction of the blade body.

[0007] In order to better prune root plants or branches, the blade body includes a blade base portion, a blade head portion and a serrated portion for pruning branches or root plants, and the blade head portion is located between the blade base portion and the serrated portion.

[0008] In order to ensure that both the front and back sides of the blade body can be used normally after installation, the serration portion includes a forward serration segment and a reverse serration segment, and the forward serration segment and the reverse serration segment are symmetrically arranged.

[0009] In order to enable the sawtooth portion to more stably hook and cut branches during pruning, the sawtooth sections of the forward sawtooth section and the reverse sawtooth section are both arc-shaped sawtooth sections.

[0010] In order to allow the sawtooth portion to trim a larger area when rotating, the sawtooth of the forward sawtooth segment has a length that gradually decreases in a direction away from the reverse sawtooth segment.

[0011] In order to improve the trimming effect of the blade body, the blade head portion is provided at two locations, and the two blade head portions are respectively located at two opposite ends of the blade base plate portion.

[0012] The sawtooth portions are provided at two locations, and the two sawtooth portions are respectively located at two ends of the blade head portion away from the blade base plate portion.

[0013] In order to improve the strength of the blade body itself, a plurality of reinforcing strips are provided, and the plurality of reinforcing strips are arranged at intervals on the blade body.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] By installing the drive shaft on the trimmer in different mounting holes, the trimming range of the blade body can be changed, so that the staff does not need to carry multiple trimming blades of different lengths when trimming different vegetation in different ranges. They only need to disassemble the original blade on the trimmer and replace it with the position of different mounting holes.

[0016] When trimming lawns or vegetation with soft roots, both the base and the head of the blade can achieve cutting. When encountering root plants or branches, the serrations can better cut and trim them, thereby improving the functionality of the blade body in actual work;

[0017] The serration part is divided into a forward serration section and a reverse serration section, so that if the serration in any direction is broken, the blade body can be turned over 180 degrees and reinstalled on the other side. At this time, the serrations in the two directions will be reversed, so that the blade body can continue to be used normally. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is combined with Figure 1 This application is described in further detail.

[0021] The present application embodiment discloses a trimmer blade. Figure 1The trimmer blade includes a blade body 1, and a plurality of mounting holes 11 are formed on the blade body 1, and the plurality of mounting holes 11 are arranged at intervals along the extension direction of the blade body 1. Any mounting hole 11 can be connected to the trimmer body, and when trimming different types of vegetation within different ranges, it is only necessary to adjust the connection between the trimmer body and a corresponding mounting hole 11 on the blade body 1.

[0022] Reference Figure 1 , the two opposite sides of the blade body 1 are integrally formed with reinforcement strips 12, and the structures and positions of the reinforcement strips 12 on the two opposite sides of the blade body 1 are the same, and the reinforcement strip 12 on one side is used as an example for explanation below. The extension direction of the reinforcement strip 12 is consistent with the extension direction of the blade body 1. And there are multiple reinforcement strips 12, and the multiple reinforcement strips 12 are arranged at intervals along the width of the blade body 1. Since the blade body 1 needs to be connected to the trimmer body through the mounting hole 11, the reinforcement strip 12 located at the mounting hole 11 is broken into multiple sections.

[0023] Reference Figure 1 The blade body 1 includes a blade base portion 13, a blade head portion 14 and a serration portion 15. The blade head portion 14 is located at one end of the blade base portion 13, and the serration portion 15 is located at the end of the blade head portion 14 away from the blade base portion 13. Both the blade base portion 13 and the blade head portion 14 can trim and cut lawns or plants with relatively soft roots; while the serration portion 15 can trim root plants or plants with branches. The blade base portion 13, the blade head portion 14 and the serration portion 15 are integrally formed, and the extension direction of the blade body 1 is the length direction from the blade base portion 13 to the serration portion 15. The blade head portion 14 and the serration portion 15 are both provided at two locations. If one blade head portion 14 and one serration portion 15 are provided as trimming portions, then the two groups of trimming portions are respectively located at opposite ends of the blade base portion 13, that is, the blade base portion 13 is located between the two trimming portions. With each rotation of the blade body 1, the two trimming parts can trim the vegetation at the same position for multiple times, making the trimmed area more neat, thereby improving the trimming quality.

[0024] The serration portion 15 includes a forward serration segment 151 and a reverse serration segment 152, and the forward serration segment 151 and the reverse serration segment 152 are symmetrically arranged along the width direction of the blade base plate portion 13. The forward serration segment 151 is taken as an example for explanation.

[0025] Reference Figure 1Each sawtooth of the forward sawtooth segment 151 is an arc-shaped sawtooth, that is, each sawtooth of the forward sawtooth segment 151 is gradually bent in an arc shape along its own extension direction in the direction away from the reverse sawtooth segment 152. The length of each sawtooth of the forward sawtooth segment 151 gradually decreases in the direction away from the sawtooth segment, that is, the distance from the tooth top of the sawtooth of the forward sawtooth segment 151 close to the reverse sawtooth segment to the blade head 14 is greater than the distance from the tooth top of the sawtooth of the forward sawtooth segment 151 away from the reverse sawtooth segment to the blade head 14. Compared with all the sawtooths being the same length, setting the sawtooth to different lengths allows the blade body 1 to have a larger cutting range during the rotation and cutting process.

[0026] The implementation principle of a trimmer blade in an embodiment of the present application is: during the process of trimming vegetation, if vegetation with different diameter ranges is encountered, the staff can remove the blade body 1 from the trimmer, and then install the drive shaft on the trimmer in different mounting holes 11 to change the trimming range of the blade body 1, without the need to carry multiple trimming blades of different lengths.

[0027] When trimming vegetation, the blade base portion 13 and the blade head portion 14 can cut lawns or vegetation with relatively soft roots to achieve trimming. The serration portion 15 can trim root plants or branches. Since the length of the teeth of the forward serration segment 151 in the serration portion 15 gradually decreases in the direction away from the serration segment, the trimming range of the serration portion 15 is between the longest and shortest teeth in the forward serration segment 151, thereby increasing the trimming range.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
