"PERFECTED SERGEANT", which is characterized by being an angular piece, whose shorter side forms the fixed jaw and the longer allows the sliding of an arm that presents its opposite end provided with a series of teeth, arranged in semicircle and angularly to the radius, between which penetrates a fingernail in which a lever ends that tilts on an axis located between the two branches of the fork that forms the control piece, to which an arched leaf spring is attached that presses on the lever keeping the clamp pressed in the interdental spaces to act as a ratchet, when the control piece that rotates on an axis arranged in the toothed head is pressed and that, at the same time, it serves as axis of rotation to the branches of a U-piece that, reinforced at its base, constitutes the mobile clamp itself, whose position is affirmed by pressing the control piece so that the claw runs one after the other teeth, increasing the pre sion that will not yield until the lever is pressed, overcoming the pressure of the spring, the claw comes out of its housing and the mobile arm can move freely.
