The invention discloses a mechanical arm for a mechanical construction platform. The mechanical arm comprises a big arm, a small arm, a telescopic driving mechanism and a rotary driving mechanism. Therotary driving mechanism comprises a rotary driving motor, a spline shaft, a spline belt wheel, a synchronous belt, a sliding sleeve, a first movable guide mechanism, a rotary tooth disc, a bearing pedestal and a guide belt wheel. The big arm and the small arm are overlaid in the vertical direction, and the small arm is located above the big arm. The small arm is connected with the big arm through the telescopic driving mechanism. The rotary tooth disc comprises a disc body, and multiple driving teeth evenly distributed along the upper circumference of the disc body. The sliding sleeve sleeves the big arm and the small arm and is in movable matched connection with the big arm through a first movable guide mechanism, and the sliding sleeve is in movable matched connection with the small arm through the first movable guide mechanism. The mechanical arm is ingenious in structural design, convenient to use and low in manufacturing cost.
