Abstract

SE DESCRIBE UNA HERRAMIENTA DE CORTE GIRATORIA (30) DESTINADA A SER MONTADA EN EL AGUJERO (22) DE UN BLOQUE QUE INCLUYE UN CUERPO SIMETRICO DE FORMA ALARGADA (32) QUE PRESENTA UNAS PARTES DELANTERA (34) Y POSTERIOR (36), TERMINANDOSE LA PARTE DELANTERA (34) EN UNA EXTREMIDAD DELANTERA DONDE EXISTE UNA PUNTA DE CORTE (44) MIENTRAS QUE LA PARTE POSTERIOR (36) TIENE UN DIAMETRO GENERALMENTE CONSTANTE Y SE TERMINA EN UNA EXTREMIDAD POSTERIOR (46). LA PARTE POSTERIOR (36) CONTIENE UN CANAL ADYACENTE A LA EXTREMIDAD POSTERIOR (46). UN RETENEDOR ELASTICO (60) RODEA SUSTANCIALMENTE LA TOTALIDAD DE LA PARTE POSTERIOR (36) Y SE EXTIENDE HACIA ATRAS MAS ALLA DE LA EXTREMIDAD POSTERIOR (46). EL RETENEDOR (60) TIENE UN SALIENTE ORIENTADO HACIA EL INTERIOR (74) QUE SE SITUA EN EL INTERIOR DEL CANAL DE TAL MANERA QUE EL CUERPO DE FORMA ALARGADA (32) Y EL RETENEDOR, QUEDEN MANTENIDOS CONJUNTAMENTE. EL RETENEDOR (60)TIENE UN DIAMETRO NO ESTIRADO SUPERIOR AL DIAMETRO DEL AGUJERO (22) DE TAL MANERA QUE CUANDO LA HERRAMIENTA DE CORTE (30) SE INTRODUCE EN EL AGUJERO (22) EL RETENEDOR (60) SE ENSANCHA CONTRA EL AGUJERO (22) PARA QUEDAR MANTENIDO EN EL, CON LO CUAL EL CUERPO (32) PUEDE GIRAR LIBREMENTE RESPECTO AL BLOQUE (14).
