4. The system according to claim 1 , wherein the bodies of said front-foot unit ( 14 ) and said rear-foot unit ( 15 ) are formed as a single body ( 116 ) which houses said connection group (GC) and leveling group (GL) of both said front-foot unit ( 14 ) and said rear-foot unit ( 15 ).

5. The system according to claim 1 , further comprising one or more pins protruding from said shoulder ( 11 ) and inserted in holes ( 21 ′, 121 ) formed in said body for receiving said blocking element of said connection groups (GC) that consist of one or more grub screws ( 26 ) positioned inside one or more threaded pass-through holes ( 27 , 27 ′; 127 , 127 ′) of said body.

6. The system according to claim 5 , wherein said one or more threaded pass-through holes ( 27 , 27 ′; 127 , 127 ′) of said body ( 16 , 116 ) are positioned alongside according to a horizontal direction in said body ( 16 , 116 ).

7. The system according to claim 1 , wherein each front-foot unit ( 14 ) and rear-foot unit ( 15 ) provides said connection group (GC) comprising a pin ( 24 ), positioned integrally in a shoulder ( 11 ), and said blocking element consists of a grub screw ( 26 ) positioned inside a threaded hole ( 27 , 27 ′; 127 , 127 ′; 45 ) of said body ( 16 , 116 ) and movable in engagement with said pin ( 24 ), and said leveling group (GL) provided with a vertical regulation mechanism in height of a lower supporting part of the foot ( 33 ).

8. The system according to claim 7 , wherein said grub screw ( 26 ) is caused to move inside a vertical hole ( 45 ) of said body ( 16 ) by a regulation mechanism positioned in said body according to a vertical direction and protruding to be housed in a hole ( 54 ) formed in said bottom ( 12 ) intersecting a hole ( 21 ″) in which said pin ( 24 ) integral with said shoulder ( 11 ), is inserted.

9. The system according to claim 1 , wherein said body ( 16 , 116 ) provides at least one interlocking pin ( 17 ) and at least one snap pin ( 18 ) respectively positioned in a hole ( 19 ) of said shoulder ( 11 ) and at least one hole ( 20 ) of said bottom ( 12 ).

10. The system according to claim 1 , wherein said regulation mechanism in height of said leveling group (GL) provides a pinion-toothed crown bevel comprising a pinion ( 34 ) rotatingly positioned inside a hole formed in a casing ( 31 , 32 ), which engages with a toothed crown ( 35 ), produced as a head of a threaded screw ( 36 ) in turn positioned in an axial threaded hole ( 37 ), internal and connected to a lower foot portion ( 33 ).

11. The system according to claim 1 , wherein said connection group (GC) comprises said blocking element consisting of a blocking grub screw ( 26 ) screwed into a threaded pass-through hole ( 27 ) of a body ( 16 , 116 ), said hole ( 27 ) having a flared outer end and being formed in a direction perpendicular to a pass-through hole ( 21 ′) which receives a pin ( 24 ) that extends from a shoulder ( 11 ) intersecting said pin.
