As a further improvement on the present invention, described hoop is set to together or twice.
As a further improvement on the present invention, described hollow cylinder structure, convex portion and hoop are formed in one structure.
As a further improvement on the present invention, described can the thickness of stretched portion be 0.5mm to 1.50mm.
As a further improvement on the present invention, the thickness of described convex portion is 1.00 mm to 2.50mm.
As a further improvement on the present invention, the width of described hoop is 1.00mm to 3.00mm, and thickness is 0.7mm to 2.50mm.
As a further improvement on the present invention, described elastoplastic material is polypropylene or polyoxymethylene.
The invention has the beneficial effects as follows:
1, because of seamless, during injection moulding, overlap and burr can not be there is at opening, jump ring can not be caused in hair cover to turn motionless or dumb, thus hair can not be caused to be enclosed within roll frame rotating abnormal and cannot using.
2, opening jump ring of the prior art, the handspike inserts in the process of jump ring, when just inserting, have outs open not strutted completely by the handspike, easily cause the axis deviation of jump ring, with hair cover axle center not exclusively on an axis, formed the handspike insert time there will be stop phenomenon, cause use to feel to have some setbacks.Use people who are unskilled if run into, the handspike firmly may be struck inward, thus cause the handspike that hair cover is struck bad.The present invention is seamless jump ring is not because having opening, and the process that the handspike inserts hair cover is very smooth and easy, avoids and occurs the problems referred to above.
