ES253094U - Perfected thrust for marchamar (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Improved pincer for marching, characterized in that it essentially comprises a supporting structure, articulated at its center and provided with two opposite main arms, oppressible and approachable with each other and two front arms of smaller proportions, equally opposite, so that the aforementioned central articulation is included between both pairs of arms, the lower front arm being the prolongation of the upper rear arm and vice versa, so that when closing, bringing forward and pressing the two main arms, the two front ones also approach, with the particularity of that the two front arms, of smaller dimensions, are, in turn, articulated to two other opposite extension pieces that form suitably guided extensions with respect to the supporting structure, said extensions being related to the arms of the supporting structure through means elastic that allow slight movements of v aiyen and, on the other hand, the upper prolongation its front end that has a nail shape, carrying in its inner-lower part a central pin presser of the latch, while the other lower extension piece bears, at its front end, a resistant block with a second lug axially sliding with respect to said block and linked thereto by elastic means, being substantially coaxial with the first pressing lug integral with the nail of the other forward extension, so that between both lugs pressure is exerted on the hand in the time to fix the latter in the right place.
