         11 . The device of  claim 10 , wherein the at least one head frame holder includes a first portion including the first end of the at least one head frame holder and a second portion including the second end of the at least one head frame holder, wherein one of the first portion of the at least one head frame holder or the second portion of the at least one head frame holder defines a central longitudinal opening, and an other of the second portion of the at least one head frame holder or first portion of the at least one head frame holder is slidingly disposed within the central longitudinal opening of the at least one head frame holder. 
     
     
         12 . The device of  claim 11 , wherein the one of the first portion of the at least one head frame holder or the second portion of the at least one head frame holder defines one or more side openings, the at least one head frame holder further including one or more locking pins disposable within the one or more side openings of the at least one head frame holder to rigidly couple the first portion of the at least one head frame holder to the second portion of the at least one head frame holder. 
     
     
         13 . The device of  claim 1 , wherein the first end of the at least one head frame holder is slidingly coupled to the base by a rail and bearing. 
     
     
         14 . The device of  claim 1 , further comprising at least two legs extending from the base, wherein the at least two legs have a first end coupled to the base and a second end spaced apart from the first end of the at least two legs. 
     
     
         15 . The device of  claim 14 , wherein the second end of the at least two legs can be moved between a first position to a second position, wherein the second end of the at least two legs is closer to the first end of the at least two legs in the first position than in the second position.
