Abstract

The clamp has two pairs of jaws (1, 2) with one pair (1) fixed directly on a pivoting support (8) of an arm (7) of an engine or by a mediation of a rapid clamp, and another pair (2) or inferior jaws articulated freely on the prior pair according to an axis. The jaws are pivoted in a reverse direction of movement and support under the arm by the mediation of a beam when the inferior jaw, pushed by the arm, contacts an object B. The axis is merged with an articulation of the support, and the jaws are articulated between them.
