         2 . The rod mounting device of  claim 1 , wherein the rod clamp unit includes a clamp housing liftably installed on the lid and at which an installation space, which has an opening portion provided at a line coaxially passing through the driving shaft of the head portion, is formed; at least one pair of jaw units installed on the clamp housing, configured to grasp a rod coupled to the driving shaft of the head portion, and moved forward and backward by a third actuator; and the third actuator installed at the clamp housing and the jaw unit and configured to rotate the jaw unit with respect to the clamp housing. 
     
     
         3 . The rod mounting device of  claim 2 , further comprising a position setting unit installed on an upper surface of the clamp housing and configured to coaxially vertically match the rod inserted into the installation space by the rod supply/recovery unit to a central axis to the driving shaft of the head portion,
 wherein the position setting unit includes first and second grasping members respectively rotated by first and second brackets on both sides of the installation space of the clamp housing and configured to grasp a lower portion of the rod, and fourth and fifth actuators installed on the first and second brackets and configured to rotate the first and second grasping members.   
     
     
         4 . The rod mounting device of  claim 1 , wherein the rod supply/recovery unit is provided with a base member installed at an edge of the lid insertion hole of the body frame and rotatably installed on a support frame, a rotating member hinge-coupled to one side of the base member and configured to grasp and rotate the end portion of the rod coupled to or separated from the driving shaft, a grasping portion installed on the rotating member and configured to clamp the end portion of the rod, a sixth actuator installed on the base member and configured to rotate the rotating member in a direction in which the rod is vertically raised or horizontally laid, and a driving portion configured to rotate the base member installed on the support frame, and the grasping portion is provided with a fixing jaw installed on an upper surface of the rotating member, a moving jaw rotatably installed on the fixing jaw, and a seventh actuator installed on the rotating member and the moving jaw and configured to rotate the moving jaw with respect to the fixing jaw. 
     
     
         5 . The rod mounting device of  claim 1 , wherein the rod containing portion is provided with first and second support rods installed to be close to the body frame, configured to support both sides of each of the plurality of rods to be contained in a state in which the plurality of rods are parallel to and in contact with each other, and inclined to enable the plurality of rods to be moved to a front side of the rod containing portion, and a guide portion installed parallel to the first and second support rods and configured to align end portions of the plurality of rods. 
     
     
         6 . The rod mounting device of  claim 1 , wherein:
 the rod elevating portion includes first and second guide roads installed at a front side of the grasping portion in parallel with each other, first and second racks respectively installed at front sides of the first and second guide roads, first and second elevating members respectively lifted along the first and second guide roads, first and second pinions installed on the first and second elevating members and engaged with the racks, and a pinion driving portion configured to drive the first and second pinions,   the first and second elevating members are provided with first and second forward/backward movement members that are installed to be simultaneously movable forward and backward by ninth and tenth actuators,   the first elevating member is provided with the rod elevating portion configured to lift the rod in the horizontal state and transfer the rod to the side corresponding to the grasping portion of the rod supply/recovery unit, and   the second elevating member is provided with the auxiliary rotating portion configured to guide the rod to be vertically raised by the rod supply/recovery unit.
