The invention discloses an air exhaust type lampshade demounting and mounting rod with a protection function. The air exhaust type lampshade demounting and mounting rod comprises a handheld rod. The outer side of one end of the handheld rod is connected with a lengthened sleeve pipe in a sleeved manner. A transverse rod is vertically mounted at the end, away from the handheld rod, of the lengthened sleeve pipe. A support rod is vertically mounted at the end of the side, away from the lengthened sleeve pipe, of the transverse pipe. An air supply sharp mouth is vertically connected to the end, away from the transverse rod, of the support rod, and one end of the air supply sharp mouth is connected with an air pipe. A protection device is arranged on the side, close to the support rod, of thetransverse rod. The ends, away from the transverse rod, of two sets of supporting rods are vertically connected with supporting plates. Antiskid pads are arranged on the sides, away from the supporting rods, of the two sets of supporting plates. According to the air exhaust type lampshade demounting and mounting rod, through cooperation of a pinched inflator pump, a manual air exhaust pump and theair supply sharp mouth, air is supplied into or exhausted from a lampshade, and therefore mounting and demounting of the lampshade are achieved, and replacement and cleaning of the lampshade are facilitated; and meanwhile, by means of the protection device, the lampshade can be prevented from falling off accidentally when demounted, and the safety of the lampshade and a user is guaranteed.
