Abstract

Improvements in the construction of portable gag devices, characterized by the fact that an apparatus consisting of a set of jaws is made, in which one of them is fixed to a fixed arm, while the other has a double articulation with a mobile arm and with the previous fixed arm, an intermediate lever being connected between both arms which articulately relates to the mobile arm and sliding inside the fixed arm, with limitation of the sliding movement by means of a support point for the activation phases, having a spring of traction that relates the fixed arm to the mobile clamp, between the two points of articulation of the same, in order to cause a tendency to the opening of the clamps, all this so that the simultaneous tightening of the two arms, for their mutual approach, overcoming the opposition of the spring, also determines the approximation of the jaws, until when the s pieces to be pressed by those is obtained an unstable situation that must be overcome accentuating the tightening, which is reached at the moment in which the point of articulation of the intermediate lever with the mobile arm is aligned with the point of support of the lever itself and with the articulation between said arm and its clamp, in which situation the position of stable pressing equilibrium is achieved, which remains unchanged until its alteration is caused when the two arms are separated.
