The invention provides a combined series telegraph pole. A fixed seat and a bearing seat are connected together by an upper end and a lower end of a ball rotating type locking seat, and are locked through a locking screw after an angle is adjusted in place, and a gravity cone is arranged on the bearing seat; and an inner taper hole is matched with an outer taper surface, after the inner taper hole and the outer taper surface are fixed, an inner taper surface and the outer taper surface which cling to each other are automatically locked through an annular lock groove and a self-locking pin which are matched with each other. A porcelain insulator is fixed on the top of a top pole column of the assembled telegraph pole. The combined series telegraph pole is simple in structure and quite convenient to manufacture, mount and use; and tools are not required when the telegraph pole is assembled, the telegraph pole is assembled quickly, conveniently, safely and reliably, and production cost and using cost are reduced.
