Embodiment Construction

[0026]The following is an explanation with reference to the figures of the blind rivet fastening device in the first embodiment of the present invention. FIG. 1 shows the blind rivet fastening device 1 before a blind rivet 2 has been mounted with the blind rivet fastening device in the original position. The blind rivet fastening device 1 fastens blind rivets 2 to fastened components such as car panels. The blind rivet 2, as shown in FIG. 1, is of the well known type and consists of a mandrel 3 and a blind rivet main body 5, and the rivet main body 5 consists of a hollow sleeve 6 and a flange 7 on one end. The mandrel 3 consists of a portion passing through the rivet main body 5, extending a long length from the flange 7 and gripped by the blind rivet fastening device 1, and a mandrel head 9 extending from the end of the sleeve 6 on the opposite side of the flange 7 with a diameter larger than the inner diameter of the sleeve. As is well known, a blind rivet 2 is applied by insertin...

Abstract

To provide a blind rivet fastening device that makes it easy to mount a blind rivet in the nose and that keeps the mounted blind rivet from falling out of the nose.
When the nose is connected slidably to the tool housing in the axial direction, the nose resists the action of the elastic pushing means and is slid so as to be pulled rearward in the axial direction, and the jaw is pulled rearward in the axial direction in the jaw guide. When this has occurred, the inner diameter of the jaw is increased, the mandrel is easily inserted into the jaw, the force pulling the nose rearward in the axial direction is released, the jaw is returned forward axially in the jaw guide by the pushing force of the elastic pushing means, and the inner peripheral surface of the jaw is frictionally engaged with the mandrel.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from Japanese Patent Application No. 2009 111053, filed on Apr. 30, 2009, the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to a blind rivet fastening device and, more specifically, to a blind rivet fastening device that makes it easy to mount a blind rivet in the nose and that keeps the mounted blind rivet from falling out of the nose.[0003]A blind rivet consists of a hollow rivet main body and a mandrel inserted into the rivet main body. The rivet main body consists of a hollow sleeve and a flange at one end of the sleeve. The mandrel passed through the sleeve is forcibly pulled until it becomes ruptured on the flange side. This distorts a portion of the sleeve so that it expands. The expanded sleeve portion and the flange secure the fastened components on both sides and fasten the rivet main body to the fastened components. A blind...
