Abstract
The invention describes a spreading tool (1) for widening openings, in particular for use in extricating trapped persons, having a drive (3) to which a pressurised medium (4) is applied and, coupled therewith in order to effect a synchronous counter-pivoting motion in the form of cutting and/or spreading elements, pivotably mounted pivot arms (16, 17) in a housing (15) accommodating the drive (3). The pivot arms (16, 17) are drivingly linked to a pressure ram assembly (48) which is displaceable in the direction of a parallel extending longitudinal central axis (53) substantially parallel with a pivot plane (20) of the pivot arms (16, 17).
