DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1: Refer to the attached specification Figure 1-3 The utility model is a mowing device for gardening, comprising a mowing device body 1, and a blade 2 is arranged on one side of the mowing device body 1. Figure 2A baffle 3 is fixedly installed on one side of the mowing device body 1, and the baffle 3 is sleeved on the outer wall of the blade disc 2. A first threaded sleeve 4 is rotatably connected to one side of the baffle 3. A first threaded rod 5 is threadedly connected to the interior of the first threaded sleeve 4. The first threaded rod 5 is movably connected to the interior of the baffle 3. A pressure plate 6 is fixedly connected to one end of the first threaded rod 5. The pressure plate 6 is slidably connected to the interior of the baffle 3. An airbag 7 is arranged on one side of the pressure plate 6. The airbag 7 is arranged inside the baffle 3. The outer wall of the airbag 7 is connected to a telescopic airbag 8. The outer wall of the telescopic airbag 8 is sleeved with an arc-shaped push plate 9, and the arc-shaped push plate 9 is slidably connected to the interior of the baffle 3.

[0024] It should be noted that, when the staff uses the mowing device to mow the lawn, first, the staff rotates the first threaded sleeve 4, so that the first threaded sleeve 4 drives the first threaded rod 5 to move through the internal thread, and then the first threaded rod 5 drives the pressure plate 6 to slide along the inside of the stopper 3, so that the pressure plate 6 squeezes the airbag 7, and presses the gas inside the airbag 7 into the inside of the telescopic airbag 8, so that the telescopic airbag 8 expands and pushes the arc-shaped push plate 9 to partly detach from the inside of the stopper 3, so that the arc-shaped push plate 9 will gradually move away from the blade disc 2 and pull the spring 10 to extend, and then the staff can start the mowing device to control the blade disc 2 to rotate and mow the lawn. At this time, the staff can push the mowing device to move and mow the lawn by pushing the handle 14, so that the arc-shaped push plate 9 is in front of the blade disc 2, and pushes away all the branches, stones and other debris in the lawn, so as to prevent the rotating blade on the blade disc 2 from colliding with branches, stones and other debris, causing the blade or branches, stones and other debris on the blade disc 2 to splash, causing harm to the staff The blade 2 is moved away from the blade disc 2 so that the blade 2 has passed by the blade disc 2 after the grass is pushed down, resulting in the grass not being mowed completely. When the staff finishes mowing the lawn, they can turn off the mowing device and wait until the blade disc 2 stops rotating to reverse and reset the first threaded sleeve 4 so that the first threaded sleeve 4 drives the pressure plate 6 to reset through the first threaded rod 5 and stops squeezing the airbag 7, thereby allowing the spring 10 to pull the arc push plate 9 to reset and reinsert the inside of the stopper 3. When the mowing device is not in use, the arc push plate 9 shrinks to the bottom of the mowing device body 1 to reduce the floor space of the mowing device, making it convenient for the staff to store the mowing device, and allowing the arc push plate 9 to press the gas inside the telescopic airbag 8 back into the inside of the airbag 7 to reset and wait for the next work.

[0025] Embodiment 2: One end of a spring 10 is fixedly installed inside the arc-shaped push plate 9, and the spring 10 is fixedly installed inside the stopper 3, see Figure 2A support frame 11 is provided on one side of the main body 1 of the mowing device, and a universal wheel 12 is fixedly installed on the outer wall of the support frame 11. Two limit rods 13 are fixedly connected to one side of the support frame 11, and the two limit rods 13 are slidably connected to the inside of the main body 1 of the mowing device. A pushing handle 14 is fixedly connected to the outer wall of the support frame 11, and two second threaded rods 15 are fixedly connected to one side of the support frame 11. The outer walls of the two second threaded rods 15 are both threadedly connected to second threaded sleeves 16, and the two second threaded sleeves 16 are rotatably connected to the inside of the main body 1 of the mowing device. The outer walls of the two second threaded sleeves 16 are sleeved with synchronous belts 17, and one end of the second threaded sleeve 16 is fixedly connected to a knob 18.

[0026] It should be noted that when the staff needs to mow the lawn to a specific height according to gardening requirements, the staff can turn the knob 18 to make the knob 18 drive the second threaded sleeve 16 to rotate, and then the second threaded sleeve 16 drives another second threaded sleeve 16 to rotate together through the synchronous belt 17, so that the two second threaded sleeves 16 drive the second threaded rod 15 to move through the threads, and the second threaded rod 15 gradually enters or escapes from the interior of the second threaded sleeve 16 through the threads, thereby changing the height of the mowing device body 1 and the blade 2 from the support frame 11 and the ground, so as to achieve the effect of adjusting the mowing height of the mowing device, which is convenient for the staff to adjust the mowing height of the mowing device according to the gardening mowing requirements and improve the application range of the mowing device.
