a combined tandem telegraph pole is characterized in that a connecting seat is fixed on a fixed seat, a connecting shaft is connected with the connecting seat and a bearing seat, and a gravity hammer is mounted on the bearing seat; an inner taper hole is fixed with an outer conical surface in a matched manner, and after the inner taper hole and the outer conical surface are matched and well fixed, an inner conical surface and the outer conical surface which are well fit are automatically locked through matching between an annular locking slot and a self-locking pin; and a porcelain insulator is fixed to the upper part of the uppermost rod string of the well assembled telegraph pole. The combined tandem telegraph pole is simple in structure, very convenient to manufacture, mount and use, does not need tools during assembly, quick, convenient, safe and reliable in assembly and lowered in manufacturing cost and use cost.
