The utility model relates to a technical field is carried to the circuit, is can not carry out the altitude mixture control and the multifunctional cement pole of cross arm liftable that provides to current cement pole cross arm. Comprises a pole body, the integral type is pre -buried when body of rod shaping has along the steel of body of rod length direction setting, and it slightly punishes inthe draw -in groove of outer groove width to have the inside groove along body of rod length direction on these steel, this steel notch exposes outside, and the steel number is at least one, still include the cross arm, this cross arm one end is equipped with the dop of card in steel, this dop can move along draw -in groove length direction in the draw -in groove of steel, it all is equipped withthe fixture block that restricts the cross arm up -and -down motion to be located upper end and the lower extreme of hugging closely the cross arm in the draw -in groove of steel. The utility model discloses when producer's processing cement pole, at the pre -buried section C structural section of pole body, assemble according to the circuit condition at the scene, through the fixed cross arm of fixing device, can realize multiple special pole type, through adjusting the cross arm position, can realize the crossing of circuit, the disinvestment simultaneously.
