Abstract: Disclosed are an umbrella pole device, an electric umbrella and a telescopic device. The umbrella pole device includes an umbrella head, a middle rod, and an umbrella pole transmission assembly. The middle rod includes a plurality of casings, the casing in an innermost part of the middle rod is an inner casing, the casing in an outermost part of the middle rod is an outer casing, and one end of the inner casing is connected to the umbrella head. The umbrella pole transmission assembly is arranged in the inner casing, including a first transmission tube and a second transmission tube. The first transmission tube is telescopically sleeved with the second transmission tube. One end of the transmission tube is rotatably connected to the umbrella head, and one of the first transmission tube and the second transmission tube is a rectangular spring.
