[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0024] Figure 1 and Figure 2 As shown, a safety cover of a hedge trimmer includes a body 1 and a chain piece 2 rotatably connected to the body 1, a protective cover 3 located above the chain piece 2 is fixedly connected to the body 1, and the protective cover 3 is arc-shaped. By setting the protective cover 3, the cut green plants can be prevented from splashing around and affecting the operator's sight and safety, thereby effectively improving the convenience and safety of using the hedge trimmer. The protective cover 3 is located above the chain piece 2 and has a plurality of mounting grooves 12, a fan 7 is fixedly connected in the mounting grooves 12, and a channel 13 is formed between the protective cover 3 and the chain piece 2, a collecting box 4 is fixedly connected to the body 1, the collecting box 4 is communicated with the channel 13, and a fan 2 10 is fixedly connected in the collecting box 4.

[0025] Figure 2 and Figure 3 As shown, when the hedge trimmer cuts green plants, fan 1 7 and fan 2 10 are started. At this time, fan 1 7 sucks the trimmed green plants into channel 13, and then fan 2 10 sucks the green plants in channel 13 into collection box 4 for collection, thereby avoiding the trimmed green plants from piling up between the protective cover 3 and the chain plate 2 to affect the line of sight. This design also facilitates the subsequent cleaning of the trimmed green plants. At the same time, the collection box 4, the protective cover 3 and the channel 13 are all made of transparent material, which can facilitate observation when the hedge trimmer is cutting the green plants.

[0026] Figure 2 and Figure 3 As shown, the collecting box 4 and the mounting slot 12 are fixedly connected to the fan 2 10 and the fan 1 7 near the channel 13. Figure 2 and Figure 3 As shown, the protective net 11 on one side can block the green plants in the channel 13 when the fan 2 10 and the fan 1 7 absorb the green plants in the channel 13 into the collection box 4, thereby preventing the green plants in the collection box 4 from being discharged from the collection box 4 through the fan 2 10 and the fan 1 7.

[0027] Figure 2 and Figure 3 As shown, an opening 6 is provided on the top surface of the collection box 4, and a door panel 5 is rotatably connected to the opening 6. Therefore, when the collection box 4 is full of green plants, the opening 6 can be opened by rotating the door panel 5. At this time, the green plants in the collection box 4 can be taken out through the opening 6. This design makes it easy to clean the green plants in the collection box 4.

[0028] Figure 2 and Figure 3 As shown, a plurality of anti-return sheets 15 are fixedly connected between the collection box 4 and the channel 13, and abutment is formed between two adjacent anti-return sheets 15. The anti-return sheets 15 are elastic. Therefore, when the fan 2 10 is started, due to the pressure difference between the collection box 4 and the channel 13, the return sheet is deformed and enters the collection box 4. At this time, the channel 13 is connected to the collection box 4, and the green plants in the channel 13 can smoothly enter the mobile phone box. When the fan 2 10 is turned off, the deformed return sheet is reset, thereby closing the channel 13 to prevent the green plants in the collection box 4 from entering the channel 13, thereby preventing the green plants in the collection box 4 from entering the channel 13, so that the collection effect of the collection box 4 is better.

[0029] Figure 2-Figure 5 As shown, a slide groove 14 communicating with the outside is opened in the protective cover 3, and a movable plate 8 is slidably connected in the slide groove 14. A spring 9 for pushing the movable plate 8 to slide is fixedly connected between the slide groove 14 and the movable plate 8. Therefore, when using the hedge trimmer, as the cutting depth of the chain piece 2 in the green plant increases, the green plant pushes the movable plate 8 to slide. At this time, due to the deformation of the extrusion spring 9 of the movable plate 8, this design enables the protection range of the protective cover 3 to be adjusted according to the cutting depth of the chain piece 2, thereby facilitating the use of the hedge trimmer. After the cutting is completed, as the chain piece 2 is separated from the green plant, the deformed spring 9 pushes the movable plate 8 to reset, thereby more comprehensively protecting the chain piece 2. Moreover, since the length of the movable plate 8 is greater than the depth of the slide groove 14, when the movable plate 8 is reset, part of the movable plate 8 is still located in the slide groove 14, so as to prevent the movable plate 8 from shaking left and right when the hedge trimmer is in use, affecting the use of the chain piece 2.

[0030] Figure 2 There are gaps between the protective cover 3 and the movable plate 8 and the chain piece 2, which can prevent the protective cover 3 and the movable plate 8 from affecting the normal use of the chain piece 2.

[0031] The above is an introduction to a safety cover for a hedge trimmer provided by the utility model. This article uses specific examples to illustrate the principle and implementation of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
