Specific embodiments

[0024] The following will refer to the accompanying drawings to describe in detail the preferred embodiments of the present utility model. 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.

[0025] It should be noted that: similar reference numerals represent 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.

[0026] Figures 1 - 3 As shown, a high - efficiency lawn mower includes a body 1, four tires 2 rotatably connected to the body 1, and a weeding blade 11 rotatably connected to the ground of the body 1. An engine 3 for controlling the rotation of the weeding blade 11 is fixedly connected to the top surface of the body 1. A handle 4 is slidably connected to the tail of the frame. Therefore, when using the lawn mower, the body 1 is pushed to move through the handle 4. At this time, the tires 2 rotate, and during the movement of the body 1, the engine 3 drives the weeding blade 11 to rotate and cut the grass.

[0027] Figures 1 - 3As shown, two adjacent tires 2 along the width direction of the body 1 are connected by a connecting rod 8, which can connect two laterally adjacent tires 2 together, making the installation more convenient and improving the installation convenience. The two connecting rods 8 are slidably connected to the body 1, and a connecting rod 9 is fixedly connected between the two connecting rods 8. Preferably, there are two connecting rods 9, which can connect the two together. When installing the tires 2, all four tires 2 can be installed on the body 1 with only one step, further saving the installation steps. The connecting rod 9 is slidably connected to the body 1, and since one end of the connecting rod 9 is fixedly connected to the handle 4, and the connecting rod 8 and the connecting rod 9 are both located on the bottom surface of the body 1, it can play a role in supporting the body 1.

[0028] Figures 1 - 3 As shown, a number of racks 7 are fixedly connected to the tail of the body 1. A gear shaft 6 meshing with the rack 7 is rotatably connected to the handle 4, and a motor 5 for driving the gear shaft 6 to rotate is fixedly connected to the handle 4. When it is necessary to adjust the distance between the weeding blade 11 and the ground, the motor 5 is started. At this time, the motor 5 drives the gear shaft 6 to rotate, and the rack 7 meshing with the gear shaft 6 slides up / down as the gear shaft 6 rotates. At this time, the body 1 also slides accordingly, so as to achieve the purpose of adjusting the distance between the weeding blade 11 and the ground. This design enables the height of the weeds after weeding to be adjusted as needed.

[0029] Figure 1 and Figure 2 As shown, there are two racks 7, and the two racks 7 are symmetrically arranged with the longitudinal section of the body 1 as the axis of symmetry. When the gear shaft 6 rotates, the two racks 7 slide under the drive of the gear shaft 6, so that the body 1 is evenly stressed and slides smoothly.

[0030] Figures 3 - 5 As shown, a chute one 12 and a chute two 10 communicating with the chute one 12 are provided on the body 1. The connecting rod 8 slides in the chute one 12, and the connecting rod 9 slides in the chute two 10. Therefore, when the body 1 slides under the drive of the gear shaft 6 and the rack 7, the connecting rod 8 slides slightly in the chute one 12 as the body 1 slides, and similarly, the connecting rod 9 slides slightly in the chute two 10, facilitating the sliding of the body 1.

[0031] Figures 3 - 5 As shown, a number of limiting strips 19 are fixedly connected to the connecting rod 8. The cross section of the limiting strip 19 is rectangular, and a limiting groove 16 communicating with the chute one 12 is provided on the frame. When the connecting rod 8 slides, the limiting strip 19 slides in the limiting groove 16. The limiting groove 16 and the limiting strip 19 limit the sliding range of the connecting rod 8, preventing the connecting rod 8 from separating from the chute one 12 during sliding, and when the sliding range of the connecting rod 8 is limited, the sliding range of the connecting rod 9 is also limited.

[0032] Figures 3 - 5 As shown, an installation groove 15 is formed in the limiting strip 19. A clamping block 14 is slidably connected in the installation groove 15. A clamping groove 13 for facilitating the clamping of the clamping block 14 is formed on the inner side wall of the limiting groove 16. A spring 17 for pushing the clamping block 14 to slide is fixedly connected between the installation groove 15 and the clamping block 14. When the limiting strip 19 slides in the limiting groove 16, as the limiting strip 19 slides, the clamping block 14 is separated from the clamping groove 13 where it is currently located, and slides into the installation groove 15 under the push of the inner wall of the limiting groove 16. At this time, the spring 17 deforms, and as the limiting strip 19 continues to slide, the deformed spring 17 pushes the clamping block 14 to be clamped into the next clamping groove 13, and at the same time, a sound is generated due to the collision between the clamping block 14 and the inner wall of the clamping groove 13. The distance that the machine body 1 slides can be prompted through the sound, so as to facilitate the control of the sliding of the machine body 1. An arc surface is provided on the top surface of the clamping block 14, which can facilitate the separation and clamping of the clamping block 14 and the clamping groove 13.

[0033] Figures 3 - 6 As shown, a number of support springs 18 are fixedly connected between the connecting rod 9 and the second sliding groove 10, which can produce a supporting effect on the machine body 1, avoid the generation of a gap between the connecting rod 9 and the connecting groove after the machine body 1 slides, and the machine body 1 is suspended. At the same time, when the machine body 1 slides, as the machine body 1 slides, the support spring 18 deforms due to extrusion and generates a reaction force on the machine body 1, so as to better support the machine body 1.
