Abstract
A clamping and/or spreading tool comprising a push or pull rod to which a mobile jaw is fixed, a fixed jaw, a gear mechanism which can be used to move the mobile jaw towards or away from the fixed jaw by moving the push or pull rod in a clamping or spreading direction, and to apply clamping and/or bracing forces between the jaws, and a lock used to block movement of the push or pull rod in an opening direction opposing the clamping or spreading direction, in order to maintain clamping and/or spreading forces produced between the jaws. A mechanism for dissipating the stored clamping and/or spreading forces enables an absorption movement of the push or pull rod in the opening direction along a pre-determined absorption course, and especially detachably blocks an absorption movement of the push or pull rod over the predetermined absorption course, in the opening direction.
