Abstract
Improved trench, characterized by comprising a tubular piece, attached at one end to a fork, the tubular part having internally housed as an axis, a longitudinal rod projecting from the two ends, which is joined together at the rear end, to a button pushbutton, which has a step, which acts as a guide for a bushing, partially housed inside the tubular part and whose circular edge presses on a spring that surrounds the central rod, being joined by the front end in solidarity, to a crosspiece having holes in it, where the fork legs are inserted, the crosspiece moving when the push button is pressed, the cutter being held by an external transverse part integral with the tubular body, where the fingers rest on the bottom.
