[0039] Further, the universal wheels 2 are installed on the bottom disc 1 at positions corresponding to the slide rails 5 and between the two ground stakes 10 corresponding to the lower end surface of the bottom disc 1.

[0040] Working principle:

[0041] The motor 14 is started, and the output end of the motor 14 drives the disc 13 to rotate. Since the first fixed column 31 is fixed at the eccentric position of the disc 13, and the two ends of the connecting plate 16 are respectively rotatably connected to the first fixed column 31 and the second fixed column 29, and the second fixed column 29 is fixed on the movable rack 9, and the movable rack 9 is limited on the fixed rack 8 through the limiting sliding block 30, therefore, the rotation of the disc 13 can drive the movable rack 9 to move along the sliding groove 28 through the connecting plate 16, and the movable rack 9 cooperates with the fixed rack 8 to cut the grass on the dam.

[0042] When it is necessary to adjust the cutting height, the electric telescopic rod 21 is started, and the output end of the electric telescopic rod 21 drives the second limiting block 20 to move downward. The downward movement of the second limiting block 20 can also drive the ground stake 10 to move downward. When the second limiting block 20 moves to contact the bottom disc 1, the ground stake 10 is just inserted into the soil, which can limit the cutting device and prevent the device from moving during the adjustment of the cutting height, thereby avoiding dangerous situations and further improving the safety of the grass cutting device. At this time, the second limiting block 20 is just below the rotating connection between the handle 3 and the second supporting plate 22, so that the second limiting block 20 releases the restriction on the rotation of the handle 3 at this time, and the handle 3 can rotate around the second supporting plate 22. When the handle 3 is rotated downward around the rotating shaft, the movable rod 25 slides in the through slot block 4 and presses the through slot block 4 at the same time, and then the second piston rod 32 moves downward to press the oil in the third hollow box 18 out of the oil delivery pipe 23 into the first hollow box 7. The oil in the first hollow box 7 rises to drive the first piston rod 27 to move upward, and then the fixed rack 8 moves upward to adjust the cutting height. At this time, the spring 12 is compressed. When the handle 3 moves upward around the rotating shaft, the movable rod 25 slides in the through slot block 4 and pulls the through slot block 4 at the same time, and then the second piston rod 32 moves upward to use the oil suction pipe 17 to suck the oil in the second hollow box 11 into the third hollow box 18. In this way, the adjustment of the cutting height is realized reciprocatingly. The adjustment of the cutting height only needs to rotate the handle 3 at the handle 3, without the need to adjust at the cutting position of the device, thereby improving the convenience of using the device, and at the same time, the adjustment of the cutting height does not need to be adjusted at the cutting position, thereby reducing the probability of injury of the hand at the cutting position, and further improving the safety of using the device.

[0043] When it is necessary to lower the cutting height, the main oil drain valve 19 is manually opened, the spring 12 restores the deformation to drive the fixed rack 8 to move downward, and the oil in the first hollow box 7 flows back into the second hollow box 11 through the oil return pipe 24, thereby realizing the lowering of the cutting height.

[0044] The utility model embodiment makes the detailed explanation in combination with the drawing, but the utility model is not limited to the above -mentioned embodiment, still can make various changes in the knowledge range of ordinary skill in the art person who has possessed under the premise of not departing from the utility model tenet.
