In the steel wire rolling process, under the effect of torsional spring between fly leaf 502 and connecting rod 501, and then can make first roller 504 compress tightly the steel wire, along with the steel wire rolling to the I-shaped wheel, can make fly leaf 502 overturn along the anticlockwise direction of right side view, simultaneously under the effect of the inside torsional spring of activity ring 503, can drive second roller 506 through activity ring 503, connecting block and arc 505 drive and remove, make second roller 506 can contact with the steel wire, and compress tightly the steel wire, in addition when the user carries out the unwrapping wire through coiling mechanism, the user drives the I-shaped wheel and sees anticlockwise rotation right side view, because of the tail end perk of steel wire, can make the steel wire tail end and arc 505 contact, coiling mechanism continues to drive the I-shaped wheel and sees anticlockwise rotation right side and can take off the structural steel wire of I-shaped wheel, high durability and convenient use.

Further, as shown in fig. 2, the two end faces of the arc-shaped bar 104 of the present embodiment are respectively embedded with magnets 105, and the opposite faces of the magnets 105 and the adjacent magnets 105 are homopolar. Because the homopolar repulsion of magnet 105, and then can adjust the clearance between arc 104, convenient to use person installs the I-shaped wheel structure on the coiling mechanism, stacks the I-shaped wheel structure in addition, can produce the suction between the magnet 105 on this I-shaped wheel structure and the magnet 105 on other I-shaped wheel structures for the I-shaped wheel structure is stacked more stably.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
