Abstract:
1. A multiple tool device, for preparing tubular elements to be welded by electrofusion, comprising: a cup member which is associable with an end portion of a tubular element; a motion transmission element for use in turning or rotating said multiple tool device; a scraper configured to remove an outer surface layer of said end portion; and a facing member adapted to face an edge of said end portion in order to render said edge perpendicular to a longitudinal axis of said tubular element, said scraper having an operating motion in one direction and said facing member having an operating motion in an opposite direction, said scraper comprising at least one first tool, said facing member comprising a second tool, said second tool being fixed to said cup member at a base thereof, said second tool having a cutting edge that protrudes from an internal surface of said base at right angles to a longitudinal axis of said cup member, wherein: said at least one first tool is fixed to a first arm of a rocker lever which is articulated to said cup member, said rocker lever having an articulation or pivot axis that is transverse to the longitudinal axis of said cup member, further comprising an elastic or spring element that pushes a second arm of said rocker lever and that abuts against said cup member; said first arm oscillates inside a slit that is formed in a side wall of said cup member; a cutting edge of said at least one first tool protrudes from the internal surface of said cup member, parallel to the longitudinal axis of said cup member; the oscillation of said first arm is limited by at least one pin associated transversely with said first arm and abutting against an outer lateral surface of said cup member; and said rocker lever is provided with a locking component adapted to lock the oscillation of said first arm, said locking component comprising at least one threaded element which engages a corresponding female thread provided in said second arm, said threaded element abutting against an outer lateral surface of said cup member.
