[0019] One end of the rotating rod 17 is rotatably inserted into the lower part of the supporting rod 16 , one end of the connecting plate 18 is fixedly connected to the rotating rod 17 , one end of the cylinder 19 is fixedly connected to the connecting plate 18 , and the outer side of the sleeve 24 is fixedly connected to the fixing rod 23 .

[0020] A fixing box 25 is fixedly mounted on the outer side of the cleaning machine body 15 , and a sensor 26 is fixedly connected to one end of the fixing box 25 .

[0021] By adopting the above technical solution, the sensor 26 senses that the cleaning machine body 15 encounters an obstacle during operation and transmits a signal to the cylinder 19, thereby adjusting the cleaning machine body 15 to avoid the obstacle.

[0022] The outer side of the connecting plate 22 is threadedly mounted with bolts 27 distributed in an array, and one end of the bolt 27 is threadedly penetrated through the connecting plate 22 and threadedly mounted on the inner side of the cleaning machine body 15 .

[0023] By adopting the above technical solution, the connecting plate 22 is fixed by using bolts 27. Removing the bolts 27 also facilitates the removal of the connecting plate 22 from the cleaning machine body 15, which is convenient for later maintenance of the components on the connecting plate 22.

[0024] The outer side of the fixing plate 11 is provided with symmetrically distributed receiving openings 28 , the inner side of the receiving openings 28 is rotatably clamped with a rotating shaft 29 , and the outer side of the rotating shaft 29 is fixedly mounted with a handle 30 .

[0025] By adopting the above technical solution, the handle 30 is exposed from the storage opening 28 by rotating the rotating shaft 29, so that the handle 30 can be used to carry and move the device.

[0028] Working principle: First, start the cleaning machine body 15 to perform the cleaning operation. When the cleaning machine body 15 encounters an obstacle, the sensor 26 is used to sense that the cleaning machine body 15 encounters an obstacle during operation and then transmits a signal to the cylinder 19, thereby adjusting the cleaning machine body 15 to avoid the obstacle. Then the cylinder 19 pushes the connecting shaft 20 to move. The connecting shaft 20 moves and rotates on the sleeve 24. At the same time, the sleeve 24 is pushed. The sleeve 24 rotates on the connecting shaft 20 to drive the fixed rod 23 to rotate. The fixed rod 23 drives the connecting plate 22 and the cleaning machine body 1 5 rotates, and the angle rotation of the cylinder 19 during this process is coordinated with the movement of the cylinder 19 by the rotation of the rotating rod 17 on the supporting rod 16, so that the extension of the cylinder 19 rotates the cleaning machine body 15 and the angle is adjusted downward. The activity adjustment of 15 relies on 14 rotating on 13, so that the cleaning machine body 15 avoids the track obstacles, avoids the cleaning machine body 15 and the obstacles made of the same metal material from contacting and causing collision damage, reduces the difficulty of work progress, and effectively protects the cleaning machine body 15 from damage, thereby prolonging the service life and reducing the maintenance cost.
