people can press the first starting switch 51, the first starting switch 51 sends a signal, the control module receives the signal and then controls the water pump 53 to be started, after the water pump 53 is started, the water pump 53 can pump the coating in the material box 2 to the second water pipe 54 through the first water pipe 52, the coating flows into the connecting pipe 55 through the second water pipe 54, the coating flows to the hose 56 through the connecting pipe 55 and then flows to the spray head 3 through the hose 56, so that the spray head 3 can spray the wall surface, the discharging effect is realized, meanwhile, the control module controls the output shaft of the driving motor 64 to rotate, so as to drive the screw rod 65 to rotate, so as to drive the nut 66 to move upwards and further drive the protective cover 67 to move upwards, when the protective cover 67 moves upwards, the protective cover 67 drives the spray head 3 to move upwards, so that the hose 56 is unwound, so as to drive the reel 57 to rotate, so as to further drive the connecting pipe 55 to rotate, the volute spiral spring 58 is twisted and deformed, when the protective cover 67 moves upwards to contact with the first travel switch 68, the first travel switch 68 sends a signal, the control module receives the signal and controls the output shaft of the driving motor 64 to stop rotating, when the output shaft of the driving motor 64 stops rotating, the control module simultaneously controls the extension rod of the first electric push rod 63 to extend for five seconds, so that the first support 62 is driven to move upwards for five seconds, the driving motor 64, the screw rod 65, the nut 66, the protective cover 67, the spray head 3 and the first travel switch 68 are driven to move upwards for five seconds, after the five seconds, the control module controls the extension rod of the first electric push rod 63 to shorten for five seconds, so that the first support 62 is driven to move downwards for five seconds, the driving motor 64, the screw rod 65, the nut 66, the protective cover 67, the spray head 3 and the first travel switch 68 are driven to move downwards for five seconds, when the first support 62 moves downwards for five seconds and then contacts with the second travel switch 69, the second travel switch 69 sends a signal, the control module receives the signal and then controls the telescopic rod of the first electric push rod 63 to stop working, and simultaneously controls the output shaft of the driving motor 64 to rotate reversely, so as to drive the screw rod 65 to rotate reversely, so that the nut 66 moves downwards and further drives the protective cover 67 to move downwards, when the protective cover 67 moves downwards, the protective cover 67 drives the spray head 3 to move downwards, the scroll spring 58 resets to drive the connecting pipe 55 to rotate reversely, so that the hose 56 is wound, so that the winding wheel 57 rotates reversely, when the protective cover 67 moves downwards and contacts with the third travel switch 610, the third travel switch 610 sends a signal, and after receiving the signal, the control module controls the output shaft of the driving motor 64 to stop working and also controls the water pump 53 to be closed; when people can press the second starting switch 71, the second starting switch 71 sends a signal, the control module receives the signal and then controls the telescopic rod of the second electric push rod 74 to extend, so as to drive the second bracket 73 to move upwards and further drive the sliding block 75, the first spring 76, the first roller 77 and the pressure sensor 78 to move upwards, when the first roller 77 moves upwards and contacts with the wall surface, the first roller 77 moves downwards and then drives the sliding block 75 to move downwards, the first spring 76 is compressed, when the sliding block 75 moves downwards and presses the pressure sensor 78, the pressure sensor 78 detects that the pressure value of the pressure sensor is consistent with the pressure value in the control module, the control module controls the telescopic rod of the second electric push rod 74 to stop extending, when people press the second starting switch 71 again, the second starting switch 71 sends a signal, the control module receives the signal and then controls the telescopic rod of the second electric push rod 74 to shorten to the minimum position, the second bracket 73 is driven to move downwards, the sliding block 75, the first spring 76, the first roller 77 and the pressure sensor 78 are driven to move downwards, when the first roller 77 moves downwards and is not in contact with the wall surface, the sliding block 75 is driven to move upwards due to the resetting of the first spring 76, so that the sliding block 75 cannot extrude the pressure sensor 78, and after the telescopic rod of the second electric push rod 74 is shortened to the minimum position, the control module controls the telescopic rod of the second electric push rod 74 to stop working; people can push the handrail 81 to move, so that the second roller 83 rotates and the third roller 85 rotates, the whole device is driven to move, the moving effect is realized, and the handrail 81 is stopped being pushed when the handrail does not need to be moved; people can push the pressing plate 97 to move downwards, so that the sliding block 95 moves downwards, the second spring 96 is compressed, the sliding sleeve 94 is driven to move downwards, the friction block 92 swings rightwards, the torsion spring 93 is twisted and deformed, when the friction block 92 swings rightwards and is not in contact with the second roller 83, people can push the handrail 81 to move, and after people release hands, the second spring 96 resets to drive the sliding block 95 to move upwards, so that the sliding sleeve 94 and the pressing plate 97 are driven to move upwards, the torsion spring 93 resets to drive the friction block 92 to swing leftwards, so that the friction block 92 is in contact with the second roller 83, the second roller 83 can be clamped, and the locking effect is realized; when the liquid level sensor 101 detects that the liquid level value of the coating in the material box 2 is lower than the liquid level set value in the control module, the liquid level sensor 101 sends a signal, the control module receives the signal and then controls the LCD display screen 102 to display the water quantity in the material box 2, meanwhile, the buzzer 103 is controlled to sound for five seconds, people can be reminded of needing to supply the coating, after the five seconds, the control module controls the buzzer 103 to stop sounding, and when the device is powered off, the control module controls the LCD display screen 102 to display and stop working.
