Self-locking manipulator with telescopic transformation performance

The utility model aims to provide a self-locking manipulator with a telescopic transformation performance, which comprises a rotating arm, a ratchet wheel, a movable rod, a fixed pulley, a fixed rod, a wire wheel, a steel wire and a speed reducing motor, wherein the movable rod is connected with the fixed rod, the speed reducing motor and the fixed pulley are mounted at two ends of the fixed rod respectively, the wire wheel is connected with an output end of the speed reducing motor, the steel wire penetrates through a hole at one end of the movable rod and is wound on the fixed wheel and the wire wheel, one end of the rotating arm is connected with the movable rod, and the ratchet wheel is mounted at the joint of the rotating arm and the movable rod. By means of self-locking of the ratchet wheel, the manipulator is more suitable for small-range operation requiring transformation.
