Abstract
A piecing device comprises a chuck and a hollow fastening sleeve. The chuck comprises a columnar thread part and a clamping claw part connected with the thread part. The clamping claw part comprises a plurality of elastic clamping claws, one ends of the plurality of clamping claws are connected with the end surface of the thread part, and the clamping claws are arranged at intervals so as to enclose a ring form. The vertical distance between the outer surface of each clamping claw and the axle center of the thread part is enlarged gradually along with the distance gradually enlarged between the clamping claw and the end surface of the thread part. The fastening sleeve comprises an inner side surface which comprises a threading part and a fastening part connected with the threading part. An inner space enclosed by the fastening part is frustum-shaped. The thread part is in threaded connection with the threading part. The fastening part is close to or far away from the clamping claw part by the relative rotation of the threading part and the thread part so as to press the clamping claws to be close to each other or loosen the clamping claws to be separated from each other. The piercing device adopts the mutual matching between the clamping jaw part and the fastening part to realize the connection of rod pieces, and is suitable for connecting the rod pieces with different sizes.

Embodiment
To combine accompanying drawing that the present invention is done one below specifically introduces.
See also Fig. 1 and Fig. 2, be depicted as the schematic representation of piecing devices 100 of the present invention, said piecing devices 100 comprise a chuck 10 and a fastening sleeve 20.
Said chuck 10 comprises a screw section 11 and a jaw portion 12 that links to each other with said screw section 12.Said screw section 11 is a column, is formed with outside thread 111 on its outer side surface.Said jaw portion 12 comprises a plurality of jaws that are separated from each other 121, and said a plurality of jaws 121 surround between an annular and per two the adjacent jaws 121 equidistance at interval.Said each jaw 121 1 end and 20 1 end ends, said screw section are fixedly linked, and the other end court extends away from the direction of the end face of said screw section 20.Said each jaw 121 comprises internal surface 121a and and the opposing outer surface 121b of said internal surface 121a towards the center of circle of surround annular.Said outer surface 121b is certain angle of inclination with respect to the axle center of said screw section 11; And along on the direction away from said screw section 11 end faces; Perpendicular distance between said outer surface 121b and 11 axle center, said screw section increases gradually, makes said jaw portion 12 external overall be taper.Said internal surface 121a comprises a clamping part 121c near said jaw 121 ends, almost parallel between said clamping part 121c and 11 axle center, said screw section.Said a plurality of jaw 121 all has certain elasticity, makes said jaw 121 to draw close each other or to scatter each other.
Said fastening sleeve 20 is hollow tube-shape, and it comprises an outer side surface 21 and an inner side surface (figure does not indicate).Said inner side surface comprises a spiro union portion 221 and an engagement portion 222 that links to each other with said spiro union portion 221.The inner space that said spiro union portion 221 is surrounded is a column, is formed with the internal thread 221a suitable with the outside thread of said screw section 11 111 on the said spiro union portion 221.The inner space that said engagement portion 222 is surrounded is a frustum-like shape, and has bigger diameter at the end away from said spiro union portion 221.
Please consult Fig. 1 to Fig. 3 in the lump; Said piecing devices 100 are when assembling; Said fastening sleeve 20 is sheathed on the said chuck 10; Wherein, said screw section 11 is threaded with said internal thread 221a through said outside thread 111 with said spiro union portion 221 each other, and said engagement portion 222 is sheathed on jaw portion 12 peripheries.Through the said fastening sleeve 20 of turn can make said engagement portion 222 near or away from said jaw portion 12; When said engagement portion 222 during near 12 motions of said jaw portion; Can oppress said jaw 121 draws close each other; When said engagement portion 222 during away from 12 motions of said jaw portion, said jaw 121 can scatter under himself elastic reaction each other.
Usually, the screw section 11 of said chuck 10 links to each other with a rod member (or pipe fitting) 200 away from an end of said jaw portion 12, and said screw section 11 can be formed in one with the Placement of said rod member 200, and gummed connects and welding etc.Said rod member 200 links to each other with another rod member (or pipe fitting) 300 through said cartridge device 100.During connection, the said fastening sleeve 20 of turn makes said engagement portion 22 away from said jaw portion 12, makes the jaw 121 of said jaw portion 12 scatter each other; One end of said rod member 300 is inserted in the said jaw portion 12; The said fastening sleeve 20 of turn makes said engagement portion 22 near said jaw portion 12 and oppress said jaw 121 to drawing close mutually; The clamping part 121c of said jaw 121 internal surface 121b interconnects said rod member 200 and rod member 300 drawing close the said rod member 300 of clamping in the process each other.
Said piecing devices adopt said jaw portion and the said engagement portion connection rod member that cooperatively interacts, and the pipe fitting that can be suitable for different size connects, and have increased the convenience of using.
In addition, those skilled in the art also can do other variation in spirit of the present invention, and certainly, these all should be included within the present invention's scope required for protection according to the variation that the present invention's spirit is done.
