发明名称 POSTAL FASTENING TOOL DEVICE
摘要 Apparatus is disclosed for gripping and pulling on an elongated mandrel of a blind rivet, and having a first handle with a supporting surface and an opening therethrough for receiving the mandrel. A second handle having a mandrel receiving portion is mounted on the tool about a pivotal axis. A jaw is mounted for movement relative to the second handle about the pivotal axis. A mandrel is insertable through the opening between the receiving portion and the jaw. A spring initially biases the jaw means into contact with the supporting surface while the second handle moves towards the closed position such that the receiving portion moves towards the jaw to cause the mandrel to become tightly gripped between it and the jaw whereupon the continued movement of the second handle to the closed position moves the jaw away from contact with the supporting surface and into tighter gripping engagement with the mandrel to forcefully pull generally upwardly on the mandrel.
