Spacing-adjustable clamping manipulator

The utility model relates to a spacing-adjustable clamping manipulator which comprises a base, an upper mechanical arm is arranged at the top of the base, an additional arm is connected to an inner cavity of the upper mechanical arm in a sliding mode, a lower mechanical arm is connected to one side of the additional arm in a rotating mode, and a power assembly is arranged at the top of the inner cavity of the upper mechanical arm. The mechanical arm has the advantage that the clamping range can be adjusted, in the actual using process, if a user wants to clamp a far object, the user drives the driving gear to rotate by controlling the motor, the driving gear drives the driven gear to rotate, and finally the additional arm can slide in the inner cavity of the upper mechanical arm; the position of the lower mechanical arm can be adjusted by adjusting the position of the lower mechanical arm, the effect of increasing the clamping range is achieved, the clamping efficiency of the clamping mechanical arm is improv
