In said structure, also between the movable end of described long-armed shape frame and magnetic bases, be provided with frame lifting rotating pin and protractor, between the middle part of long-armed shape frame and magnetic bases, be connected with frame lifting rotational positioning stretching bar, form three positive port scribers of a kind of oblique.
In aforementioned or said structure, also at described connecting support, be provided with slip eccentric scale pressure pin on by slideway conjunction, the connecting support that has described scale pressure pin at slip eccentric scale pressure pin upper sliding sleeve, described scale pressure pin, by rotating pin and scale pressure pin connecting support phase fit, forms a kind of quadrature, oblique, the eccentric three port scribers of handing over.
In said structure, described fixture also adopts bundling belt, matches as fixture with described magnetic bases.
The invention adopts the designed this three port scribers of technique scheme, can extensively be suitable for following multiple three port opening line: 1, isometrical pipe three ports of quadrature; 2, quadrature reducing pipe three ports; 3, isometrical pipe three ports of oblique; 4, oblique reducer tee mouth; 5, quadrature, oblique reducing, isometrical eccentric three-way mouth; And, 6, pipe quadrature, oblique, the eccentric cone of handing over; 7, pipe quadrature, oblique, the eccentric spheroid of handing over; 8, pipe quadrature, oblique, the eccentric bend pipe etc. of handing over, 9, large arm femalely manages (body) with one voice with little; 10, pipe (body) gap.
During use, open magnetic switch by magnetic bases, inhale solid on pipeline to be onstructed, or with bundling belt, magnetic bases are fixed on pipeline, according to setting arm radius, sniperscope is adjusted to the corresponding scale position on scale pressure pin, open sniperscope switch, sniperscope with scale pressure pin on pipe surface, take connecting support as the center of circle, along counterclockwise turn, with recording pen, sniperscope is incident upon to the lip-deep infrared light spot of pipe and retouches and link up, there are three port opening line, with cutting torch, cut out three ports.When to oblique three port line, according to setting arm oblique angle, the respective corners number of degrees on contrast protractor, adjust frame lifting rotational positioning stretching bar, then press aforesaid operations method and use, and realize various oblique three port line opening operations.When eccentric three-way mouth is rule, take off scale pressure pin rotating pin, change slideway conjunction together with slip eccentric scale pressure pin, scale pressure pin rotating pin is linked on scale pressure pin connecting support together with sniperscope, according to setting arm eccentricity value, adjust the corresponding scale position of scale pressure pin connecting support on eccentric scale pressure pin, last, according to aforementioned operation method, use, complete the operation of various eccentric three-way mouth line opening.
The invention is through this three port scribers of trial-production, have and be widely used, easy to use, demonstrate pipeline rules fast and accurately with one voice, for various pipelines (body), accelerate improvement and installation a kind of desirable scriber is provided, there is outstanding essential characteristics and significant advantage, be deeply subject to those skilled in the art's favorable comment.
