1. A multi-joint driven console box for construction equipment, the multi-joint driven console box being configured to control a control lever while allowing a driver's elbow to be placed thereon, the multi-joint driven console box comprising:
a multi-joint driven forward and backward drive mechanism configured to enhance forward and backward movements of the multi-joint driven console box through multi-joint operations; and
a stand control box connected to a top of the multi-joint driven forward and backward drive mechanism,
wherein the multi-joint driven forward and backward drive mechanism comprises:
a movable link top coupling bracket connected to an underside of the stand control box in such a manner as to be movable forwardly and backwardly;
a fixed link underside coupling bracket spaced apart from the movable link top coupling bracket by a given distance in up and down directions to fixedly support undersides of a first link and a second link; the first link and the second link spaced apart from each other by a given distance to allow one side of each of the first link and the second link to be connected to an underside of the movable link top coupling bracket and another side of each of the first link and the second link to be connected to a top of the fixed link underside coupling bracket;
a link plate coupled to the movable link top coupling bracket corresponding to a center point between top ends of the first link and the second link and the fixed link underside coupling bracket corresponding to a center point between underside ends of the first link and the second link by hinge pins; and
a link plate forward and backward drive mechanism disposed between the link plate and the fixed link underside coupling bracket to rotate the link plate forwardly and backwardly within a range of a given angle in an alternating manner, to operate the first link and the second link and to thus move the multi-joint driven console box forwardly and backwardly.
