A lifting component is provided inside the box body 1, and the front and rear sides of the bottom of the connecting plate 2 are fixedly connected to damping rods 11, and the bottoms of the two damping rods 11 are fixedly connected to the front and rear sides of the top of the buffer plate 12, and both ends of the driving rod 5 are fixedly connected to rotating rods 6, and the driving rod 5 is rotatably connected to the inside of the fixed block 4 through one of the rotating rods 6, and the driving rod 5 is rotatably connected to the inside of the movable block 7 through the other rotating rod 6.

[0025] Specifically, the box body 1 is used to accommodate internal parts, the connecting frame 20 is used to connect the loosening rod 21, the connecting plate 2 and the base 3 are used to support the box body 1, and the connecting plate 2 and the base 3 can provide support for the box body 1, the buffer plate 12 is used to connect the bottom universal wheel 13 and the top buffer assembly, the universal wheel 13 is used to facilitate the movement of the entire device, the fixed block 4 is used to drive the driving rod 5 to rotate, the driving rod 5 is used to generate power, and the rotating rod 6 is used to provide the axis of rotation of the driving rod 5. When the fixed block 4 moves, it will drive the driving rod 5 to rotate around the rotating rod 6. When the driving rod 5 rotates clockwise around the rotating rod 6, a pulling force will be generated, and when the driving rod 5 rotates counterclockwise around the rotating rod 6, a thrust will be generated. The movable block 7 is used to The compression spring 8 is used to provide a buffering and absorbing pressure function. The positioning seat 10 is used to fix the light rod 9. The light rod 9 is used to guide the movable block 7 to move. When the driving rod 5 rotates counterclockwise around the rotating rod 6, a thrust is generated, thereby pushing the movable block 7 to move the movable block 7 to squeeze the compression spring 8, thereby buffering and absorbing the impact force. When the driving rod 5 rotates clockwise around the rotating rod 6 to generate a pulling force, the movable block 7 will be pulled to move, thereby stretching the compression spring 8 to release the impact force. The compression spring 8 is sleeved on the outer periphery of the light rod 9.

[0026] Reference Figure 1 - Figure 3 The lifting assembly includes a motor 14, which is fixedly connected to the inner top of the box body 1, and a threaded rod 15 is fixedly connected to the output end of the motor 14. The outer periphery of the threaded rod 15 is threadedly connected to a movable sleeve 16. The left and right sides of the movable sleeve 16 are fixedly connected with L-shaped plates 18, and the bottoms of the two L-shaped plates 18 are fixedly connected to the top of the connecting frame 20. The middle part of the box body 1 is fixedly connected to a limiting frame 19, and the threaded rod 15 penetrates the limiting frame 19. The front and rear sides of the movable sleeve 16 are fixedly connected to the limiting plates 17, and the two limiting plates 17 are respectively slidably connected to the inside of the limiting frame 19. The front and rear sides of the limiting frame 19 are provided with sliding grooves, and the two limiting plates 17 are slidably connected in the sliding grooves.

[0027] Specifically, the motor 14 is used to generate power, the threaded rod 15 is used to convert motion, and the movable sleeve 16 is used to transmit motion. The threaded rod 15 is driven to rotate by the motor 14, so that the movable sleeve 16 threadedly connected thereto will move along the axis of the threaded rod 15. The rotational motion generated by the motor 14 is converted into linear motion through the threaded rod 15 and the movable sleeve 16. The L-shaped plate 18 is used to transmit motion. The movable sleeve 16 and the connecting frame 20 are connected through the L-shaped plate 18, so that when the movable sleeve 16 moves, it can drive the connecting frame 20 to move accordingly. The limit plate 17 is used to limit the moving range of the movable sleeve 16 to prevent the movable sleeve 16 from rotating with the rotation of the threaded rod 15. The limit frame 19 is used to accommodate two limit plates 17.

[0028] Working principle: During use, when the universal wheel 13 passes through the earth pit, the space between the buffer plate 12 and the connecting plate 2 will be reduced, so that the driving rod 5 will rotate counterclockwise around the rotating rod 6 to generate thrust to push the movable block 7 to move toward the positioning seat 10 and squeeze the compression spring 8. The impact force is buffered and absorbed by the compression spring 8 and the damping rod 11. After the universal wheel 13 passes through the earth pit, the distance between the buffer plate 12 and the connecting plate 2 increases, so that the driving rod 5 resets and rotates clockwise around the rotating rod 6, and the compression spring 8 loses pressure and resets. Secondly, when it is necessary to adjust the distance between the loosening rod 21 and the lawn, start the motor 14, and the motor 14 drives the threaded rod 15 to rotate. When the threaded rod 15 rotates, the movable sleeve 16 moves along the axis of the threaded rod 15, so that the connecting frame 20 connected through the L-shaped plate 18 can drive the loosening rod 21 to move vertically.
