摘要： The method of the present invention is intended to be used in association with a headed fastener such as a tree nut, but not limited to a tree nut. The present method contemplates embodiments of a riveting pin having protuberances that cause the flared end of the shaft(13) to be flared in one or more discontinuous portions of the circumference of the shaft, whereby "push out" and "spin-out" are deterred. Where the length of the fastener shaft(13) is no longer than the thickness of the material(2) through which it is inserted, a first design of flaring pin is provided. Where the length of the shaft of the fastener employed is greater than the thickness of the material through which it extends, a second embodiment of flaring pin is employed. In the former case, at least one discrete portion(67,69,71,73) of the circumference of the shaft is flared into the wall of the passageway through which the shaft(13) extends. In the latter case, at least one portion of the circumference of the shaft enters the wall of the passageway and at least one other portion folds over the exterior surface of the material.
摘要翻译：本发明的方法旨在与诸如树形螺母的头部紧固件相关联使用，但不限于树形螺母。本发明的方法考虑到具有突起的铆钉的实施例，其使得轴（13）的扩口端在轴的圆周的一个或多个不连续部分中扩张，由此“推出”和“脱出”是却步。在紧固件轴（13）的长度不超过其被插入的材料（2）的厚度的情况下，提供扩口的第一设计。所使用的紧固件的轴的长度大于其延伸通过的材料的厚度，采用扩口的第二实施例。在前一种情况下，轴的圆周的至少一个离散部分（67,69,71,73）被扩张到轴（13）延伸通过的通道的壁中。在后一种情况下，轴的圆周的至少一部分进入通道的壁，并且至少一个其它部分折叠在材料的外表面上。

摘要： A portable device (10) for inserting fixing elements (100) into predefined seats (210) in a work piece, the portable device including a drive head (12); a drive rod (20) extending downward from the drive head; a hollow nose piece (50) slidably fit around a lower end of the drive rod, the nose piece being attached to the head and being movable vertically by a predetermined distance with respect to the head and the drive rod; a magazine (60) mounted on the nose piece at a predetermined angle with respect to a lower face of the nose piece for feeding a first t-nut fixing element into a horizontal slot (52) on the lower face the nose piece; and a drive mechanism providing a pulsating force produced by a pressurized fluid to an upper end of the drive rod when downward pressure is applied by a user on the drive head. The pulsating force on the drive rod drives the first t-nut fixing element into the predefined seat in the work piece.
