A multi-functional riveter having a hollow body head with an extended hand grip, said hollow body head having therein a hinged lever, one end of said lever being fastened to a transmission shaft, said transmission shaft being coupled to a hinged press handle extending external said hollow body head of the riveter to provide an activating force;
- the other end of said lever being connected to a sleeve, said sleeve comprising means for providing a rivet-pulling apparatus, a nut-pulling apparatus, or an anchor riveting apparatus to be used interchangeably as desired, and
- wherein said rivet-pulling apparatus comprises a rivet holding tube adapted to be to a lower end of said sleeve, said rivet holding tube has two conical blocks, one press block, and one coiled spring disposed in that order therein, an outer sleeve head surrounding said holding tube and adapted to be attached to said hollow body head at a base end thereof, said outer sleeve head being secured to a fixed screw nut threadedly secured thereto and a sleeve ear threadedly secured to said fixed screw nut, said rivet holding tube adapted to be linearly displaced by said sleeve for pulling a rivet by an activating force derived from the press handle which is concurrently displaced;
- wherein said nut-pulling apparatus comprises a pulling rod adapted to be located within said sleeve, an upper end portion of said pulling rod constituting a press head which is rotatably located within an outer screw tube adapted to be threadedly secured to an upper end of said said sleeve, a lower end of said pulling rod constituting an outer screw thread;
- said body head being secured to an outer sleeve head, said outer sleeve head being threadedly secured to an adjustable screw having a set screw nut mounted thereon, said pulling rod being displaced responsive to a displacement of said press handle thereby to force a pulling nut adapted to be threadedly secured to said pulling rod to be firmly attached to a metal lamella;
- wherein said anchor riveting apparatus comprises a pull tube adapted to be attached to a base of said sleeve, a base of a said pull tube constituting a square pull block which has a U-shaped slot formed through a frontal end therefore;
- an outer sleeve head adapted to be attached to said hollow body head, said outer sleeve head extending externally of said hollow body head, said pull block being slideably displaceable within said outer sleeve head, a set screw nut is secured between the hollow body head and said outer sleeve head, said set screw nut being used to determine the position of said outer sleeve head with respect to stopper block having a U-shaped slot, said recovery rod adapted to extend through said sleeve and extending through said outer sleeve head and said pull tube, a press head being secured to an upper end of the recovery rod, a screw nut and a coiled spring being disposed at a mid-section of the recovery rod, said recovery rod having a base end formed in a cross-sectional shape of a tapered cross, said pull tube being displaced resonsive to a displacement of said sleeve by said press handle, resulting in a displacement and expansion of an anchor rivet, wherein said cross-sectional shaped tapered cross of said recovery rod is adapted for contiguously interfacing with and rotationally adjusting the position of a screw rod of an anchor rivet;
- and
- said construction of the multi-functional riveter being used interchangeably with said rivet-pulling apparatus, said nut-pulling apparatus, and said anchor riveting apparatus.
