Continuous multi-joint mechanical arm device

The invention provides a continuous multi-joint mechanical arm device. The continuous multi-joint mechanical arm device comprises two parts, i.e. a pedestal and a mechanical arm, wherein the pedestal part consists of a driving part, a lower motor fixing plate, an upper motor fixing plate, a lower pulley plate, an upper pulley plate, a pulley component and connecting rods; the connecting rods are arranged among the plates; the driving part comprises a motor, a coupler and a screw rod; the mechanical arm consists of a joint with two freedom degrees and a plurality of joint backbones; each joint and each joint backbone are of the same structure; the driving part is arranged in the pedestal of the mechanical arm device; the other end of the driving device is connected with a rope; the other end of the rope is fixed to joint plates of the joint backbones. The mechanical arm provided by the invention is flexible in structure, so that the continuous multi-joint mechanical arm device is good in obstacle avoidance ability; the mechanical arm is applied in a narrow and complex work space environment, such as ruins rescuing and mechanical fitting assembly, so that the continuous multi-joint mechanical arm device is wide in application range.
