Mechanical arm for intelligent robot

The mechanical arm for the intelligent robot comprises a mechanical arm body, an article taking end and a taking mechanism are installed at one end of the mechanical arm body, the taking mechanism is installed on the inner wall of the article taking end, a two-way lead screw is movably installed on the inner wall of the taking mechanism, and the two-way lead screw is movably installed on the mechanical arm body. Multiple sets of first threaded rods are movably mounted on the inner wall of the taking mechanism, and a mounting base is mounted at the bottom of the mechanical arm body. According to the mechanical arm, by installing the taking mechanism, when objects made of different materials are taken by the mechanical arm, stable taking can be conducted without replacing the taking end, non-iron materials can be clamped and taken by the mechanical arm through installation of the taking mechanism, iron objects can be adsorbed and taken, and the mechanical arm is convenient to use. And in this way, when the mech
