[0046] The suction cup 25 is arranged inside the machine body 1 and close to the moving port 26 of the machine body 1, and the suction cup 25 can move outside the machine body 1 through the moving port 26;

[0047] The connecting rope 24 has one end connected to the take-up roller 23 and the other end connected to the suction cup 25, and the connecting rope 24 is tensioned and adjusted by a tensioning member;

[0048] And a driving member, which is installed on the support plate 21 and can drive the rotating shaft 22 to rotate, so as to recover the suction cup 25 by winding the connecting rope 24;

[0049] Specifically, the storage battery 12 can supply power to the machine body 1, eliminating the need for additional wire power supply, realizing a wireless function, reducing costs, and facilitating the portability of the machine body 1. The machine body 1 can be used to wipe the outer side of the glass. When the closing plate 28 moves downward, the moving port 26 can be opened, and the suction cup 25 can be taken out. The suction cup 25 is adsorbed to the inner side of the glass and connected to the machine body 1 through the connecting rope 24, which can prevent the machine body 1 from falling and being damaged or injuring pedestrians, providing anti-fall protection for the machine body 1. The rotation of the rotating shaft 22 can drive the take-up roller 23 to rotate, wind the connecting rope 24, and store the suction cup 25 inside the machine body 1.

[0050] In this embodiment, a storage groove 27 is provided on the inner bottom wall of the moving port 26, and a closing plate 28 is slidably arranged in the storage groove 27 in a matching manner.

[0066] Specifically, when the motor 44 is started, it can drive the worm 42 to rotate. The worm 42 can drive the worm gear 41 to rotate, thereby driving the rotating shaft 22 and the winding roller 23 to rotate, and then winding the connecting rope 24, facilitating the fixing of the suction cup 25.

[0067] In this embodiment, a slot 51 is formed on the inner top wall of the moving opening 26. A plug board 52 is fixedly connected to the top of the closing board 28. The plug board 52 can be inserted into the slot 51. A locking opening 53 is formed on one side of the plug board 52. A locking rod 54 is inserted into the locking opening 53.

The suction cup 25 is adsorbed on the inner wall of the glass, and the machine body 1 can be used to wipe on the outer wall of the glass. The suction cup 25 and the connecting rope 24 can prevent the machine body 1 from accidentally falling, and can provide anti-falling protection for the machine body 1. After the wiping is completed, the motor 44 is started to reverse, and then the winding roller 23 can be driven to reverse, and the connecting rope 24 can be retracted to the outside of the winding roller 23. During the process of retracting the connecting rope 24, the connecting rope 24 will press down on the tensioning roller 35. When the tensioning roller 35 moves downward, it can drive the pressing plate 33 to move downward. The pressing plate 33 moves downward to squeeze the first spring 38 to deform. The reaction force generated by the deformation of the first spring 38 can push the tensioning roller 35 upward to tension the connecting rope 24 and prevent the connecting rope 24 from loosening. The suction cup 25 then enters the machine body 1. Then, the locking rod 54 is pulled again, and then the closing plate 28 is reset. The locking rod 54 is released, and the second spring 56 is reset to drive the locking rod 54 to insert into the locking opening 53, so as to fix the closing plate 28, and further prevent foreign matters from entering the machine body 1 through the moving port 26.
