ABSTRACT:
The present invention relates to a multi-functional riveter, whose basic structural components include a body and a body head having a hollow upper portion with an extended hand grip. Located within the interior of the body head is a lever hinged thereto. The one end of the lever is connected to a transmission shaft which, in turn, is attached to a press handle extended and exposed to the outside of the body. The other end of the lever is coupled with a sleeve. The basic structures mentioned above are all indispensable parts of a riveter layout. The functional enhancement and improvement embodied in the present invention are based on specific mechanical arrangements designed to allow a rivet-pulling apparatus, a nut-pulling apparatus, and an anchor rivet apparatus to be integrally disposed within a riveter through its sleeve, resulting in a convenient and multi-functional riveter with the characteristics of a structural simplicity, among other things.
