• an electric motor housing and an electric motor disposed in the electric motor housing, a machine body and a bridging member mounted to the machine body, the bridging member is rotatably connected to the electric motor housing, and the clutch device comprises:
• a slide chute formed in the bridging member;
• and
• a triggering member rotatably supported on the electric motor housing, and having a first end provided with a sliding column which is slidaby fitted in the slide chute, and a second end provided with a toggling rod which is configured to stir the electric motor to move,
• wherein when the bridging member drives the slide chute to move, the sliding column slides along the slide chute so as to rotate the triggering member, and when the triggering member rotates, the toggling rod stirs the electric motor to rotate with respect to the electric motor housing;
• wherein the electric motor drives a brushroll of the upright vacuum cleaner to roll by a drive belt and is rotatable between a first vertical position of tensioning the drive belt and a first inclined position of loosening the drive belt;
• the bridging member is rotatably connected to the electric motor housing so that the machine body is rotatable between a second vertical position and a second inclined position;
• when the machine body is moved from the second vertical position to the second inclined position, the bridging member drives the electric motor to move from the first inclined position to the first vertical position by the triggering member.
