Cable-free modularized reconfigurable mechanical arm system

The invention relates to a cable-free modular reconfigurable mechanical arm system, and relates to the field of mechanical arms, every two adjacent functional modules are detachably connected through a docking mechanism module, and the functional modules are joint modules or connecting rod modules. The butt joint mechanism module comprises two butt joint fixed heads and a butt joint movable head, one ends of the two butt joint fixed heads are fixedly connected with the two adjacent function modules respectively, and the two ends of the butt joint movable head are detachably connected with the two butt joint fixed heads respectively. The mechanical arm has the beneficial effects that all components of the mechanical arm are modularly designed, the multiple joint modules, the butt joint mechanism modules and the connecting rod modules form a module library, and mechanical arm assembly of different configurations can be achieved through different permutation and combination of the multiple joint modules and the
