Specific embodiments

[0023] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present utility model.

[0024] It should be noted that: similar reference numerals denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0025] Figure 1 and Figure 2As shown in the figure, a handheld lawn mower includes a machine body 1. Embedded grooves 6 are provided on both side walls of the machine body 1. Balance plates 4 are rotatably connected in both of the two embedded grooves 6. The balance plates 4 are hinged in the embedded grooves 6 through pin shafts 8. A torsion spring 7 for driving the balance plates 4 to rotate is provided between the pin shafts 8 and the balance plates 4. Therefore, when using the lawn mower, the torsion spring 7 of the deformation groove drives the balance plates 4 to rotate around the pin shafts 8. During the rotation of the balance plates 4, the balance plates 4 are separated from the embedded grooves 6 until the balance plates 4 are in an inclined state. At this time, an angle less than 90° is formed between the balance plates 4 and the machine body 1. When using the lawn mower again, when the lawn mower tilts during turning, the balance plates 4 come into contact with the ground and support the machine body 1, so that the machine body 1 is kept balanced. This design plays a role in keeping the balance of the machine body 1 when the lawn mower turns, thereby reducing the operation difficulty of the operator and improving the convenience of the mowing process.

[0026] Figure 1 and Figure 2 As shown in the figure, a control frame 2 is slidably connected to the machine body 1. A through groove 5 communicating with the embedded groove 6 is provided on the control frame 2. The balance plate 4 has two states. In the first state, the balance plate 4 is located in the embedded groove 6 due to the restriction of the control frame 2. At this time, a gap is generated between the control frame 2 and the machine body 1 and the through groove 5 is offset from the embedded groove 6. At the same time, due to the acting force, the torsion spring 7 deforms. The first state can accommodate the balance plate 4 in the embedded groove 6, so as to facilitate the transportation or storage of the lawn mower, effectively reducing the floor area of the lawn mower. In the second state, the control frame 2 is pressed down until the inner top surface of the control frame 2 abuts against the top surface of the machine body 1. At this time, the through hole on the control frame 2 is aligned with the embedded groove 6. Since the acting force of the control frame 2 on the balance plate 4 disappears, the deformed torsion spring 7 drives the balance plate 4 to rotate outwards, so that the balance plate 4 is separated from the embedded groove 6 until the balance plate 4 is in an inclined state. At this time, the balance plate 4 is opened and plays a supporting role when the lawn mower turns, preventing the machine body 1 from tilting or toppling during the turning process. The lengths, widths and heights of the through groove 5 and the embedded groove 6 are all the same. This design enables the balance plate 4 to gradually rotate towards the embedded groove 6 as the control frame 2 is pushed when the control frame 2 is pulled upwards. At this time, the through groove 5 has enough space to facilitate the rotation of the balance plate 4.

[0027] Figure 1 and Figure 2 As shown in the figure, inclined surfaces 10 are provided on the inner bottom surfaces of the through groove 5 and the embedded groove 6. When the balance plate 4 is separated from the embedded groove 6, the bottom surface of the balance plate 4 fits with the inclined surface 10. By providing the inclined surface 10, when the balance plate 4 fits with the inclined surface 10, the balance plate 4 is in an inclined state. Furthermore, when the machine body 1 is inclined, the balance plate 4 can better contact the ground, so as to keep the machine body 1 balanced.

[0028] Figures 1 - 5As shown in the figure, a rib 16 is fixedly connected to the inclined surface 10 of the through groove 5. A groove 15 for the rib 16 to be inserted into is formed on the side wall of the balance plate 4 close to the rib 16. Arc surfaces 17 are provided on both the rib 16 and the groove 15. Therefore, when the through groove 5 and the embedding groove 6 are opposite to each other, the deformed torsion spring 7 drives the balance plate 4 to rotate outwards until the rib 16 is inserted into the groove 15. At this time, the balance plate 4 is fixed, thus preventing the balance plate 4 from rotating in the reverse direction due to the push of the ground when the machine body 1 is tilted. This design plays a role in fixing the balance plate 4, thereby making the supporting effect of the balance plate 4 better.

[0029] Figures 1 - 5 As shown in the figure, a plurality of sliders 9 are slidably connected to the machine body 1. A plurality of sliding grooves 12 for the sliders 9 to slide are formed on the side wall of the control frame 2 close to the machine body 1. Therefore, when the control frame 2 is pulled up and down, as the control frame 2 slides, the sliders 9 slide in the sliding grooves 12, and the sliding grooves 12 and the sliders 9 can limit the sliding range of the control frame 2, preventing the control frame 2 from separating from the machine body 1 during the sliding process and affecting the next use. Moreover, a handle 3 for driving the control frame 2 to slide is fixedly connected to the top surface of the control frame 2, which can facilitate the sliding of the control frame 2 and improve the operation convenience.

[0030] Figures 1 - 5 As shown in the figure, a plurality of installation grooves 11 are formed on the machine body 1. The sliders 9 slide in the installation grooves 11. A clamping groove 13 communicating with the sliding groove 12 is formed on the control frame 2. A spring 14 for pushing the sliders 9 to slide is fixedly connected between the installation grooves 11 and the sliders 9. Therefore, when the control frame 2 is slid upwards, as the control frame 2 slides, the inner bottom surface of the through groove 5 pushes the balance plate 4 to rotate into the embedding groove 6 during the sliding process. At this time, the torsion spring 7 deforms, thus playing a role in retracting the balance plate 4. After the balance plate 4 completely enters the embedding groove 6, the sliders 9 and the clamping grooves 13 are opposite. At this time, the deformed spring 14 pushes the sliders 9 to be inserted into the clamping grooves 13, thereby fixing the control frame 2 and preventing the control frame 2 from sliding up and down during the movement of the machine body 1. This design plays a role in controlling the control frame 2.

Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
