When the second wheel 207 rotates, the first rotating shaft 205 and the second bevel gear 211 are driven to rotate. Since the second bevel gear 211 is meshed with the first bevel gear 210, the second bevel gear 211 drives the stirring shaft 208 to rotate through the first bevel gear 210, and the stirring shaft 208 further drives the multiple groups of stirring blades 209 to rotate inside the glue storage tank 201, so that the multiple groups of stirring blades 209 stir the metal repair agent inside the glue storage tank 201, ensuring that the components are uniform and preventing the occurrence of Layering, start the electric turntable 301, so that the support arm 302 can be adjusted in angle, further adjust the spraying position of the multiple groups of glue spray heads 408, start the delivery pump 401, so that the metal repair agent inside the glue storage tank 201 enters the transfer shell 405 through the No. 1 glue delivery hose 402, the No. 2 glue delivery hose 403 and the rotary joint 404, the metal repair agent entering the transfer shell 405 enters the glue spray hose 407 through the No. 3 glue delivery hose 406, and the metal repair agent entering the glue spray hose 407 is evenly sprayed onto the polished cracks on the ventilation duct through the multiple groups of glue spray heads 408, forming a strong bonding force with the corresponding ventilation duct cracks, thereby achieving crack repair.

[0045] The external wall-climbing robot 101, electric turntable 301, servo motor 312, grinder 310, delivery pump 401, camera 105 and lighting lamp 106 of a cabin ventilation duct repairing device of the present invention are purchased on the market, and technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for creative labor by technicians in this field.
