The invention relates to a tool, suitable for body shops for correcting damaged vehicle body sheets, but also suitable for saving people trapped in a damaged vehicle and also for other applications that require opposite codirectional forces of high intensity with a rectilinear movement of a movable element, which is practical and independent from external energy sources. The tool ( 1 ) uses, as source of rotational movement, a common electric screwer ( 2 ) connected in a releasable way within the box ( 70 ) of said tool, with its driven shaft connected to a screw mechanism which supports in translational movement a movable element ( 10 ). The box of the tool has a front face ( 8 ) and a rear face ( 23 ), arranged at the lend of the side faces ( 29, 29 ') and the lower face kept together by the four screw pulling elements ( 28, 28 ') tightened by respective four nuts ( 25 ). On the front face ( 8 ) a fixed element ( 9 ) is connected, in which telescopically slides the movable element ( 17 ) operated by the screwer ( 2 ). The fixed element ( 9 ) and the movable element ( 10 ) have threads ( 16, 17 ) at respective distal lends, to allow assembling to said tool ( 1 ) elements interfacing to force application surfaces on the vehicle body. On the rear face ( 23 ) an screw threaded element ( 24 ) is provided for connection of said interface elements.
