The draw ring can be by pulling-on piece mounting ring set wherein when being close for two pull heads；The second clamping plate portion include upper plate portion with
And lower board unit, in the upper plate portion positioned at the pulling-on piece mounting ring remote first pull head side offer one lead to
Groove, is provided with a reed in the side of the close pulling-on piece mounting ring of the groove, when the reed includes nature to
The bent plate portion of upper bending and the folded plate of one end of the generallyperpendicular remote pulling-on piece mounting ring for being connected to the bent plate portion
Portion, the folded plate portion is inserted into the slot and the plate when being in straightened condition after the bent plate portion is pressurized
The lower prong in portion can pass through the slot and protrude from the lower surface of the upper plate portion；In the remote draw ring of the draw ring
One end of mounting ring is provided with extension plate portion, magnet is provided with the extension plate portion, when the draw ring entangles the pulling-on piece
The lower end of the magnet can be attracted and conform to the upper surface of the upper plate portion during mounting ring, and the pulling-on piece can be attracted
And fit in the upper end of the magnet.
It is of the present utility model that there are the anti-double pull heads for opening function using above-mentioned technical proposal, when the first pull head and second are drawn
When close, by draw ring to the side oscillation of the second pull head one, pulling-on piece is passed through into the draw ring, then draw ring is enclosed on pulling-on piece mounting ring
Wherein, now the lower end of magnet is attracted and conforms to the upper surface of the upper plate portion, then by pulling-on piece to the side oscillation of magnet one,
And pulling-on piece is fitted in the upper end of the magnet, on the one hand draw ring is avoided with vibration or mobile and light by the effect of magnet
Easily depart from upper plate portion, on the other hand can also attract to fix pulling-on piece, pulling-on piece is not arbitrarily swung, will not unexpected scratching arrive other
On article, safe to use, and integrally-built steadiness ensure that.It is of the present utility model that there are the anti-double pull heads for opening function,
Effectively it can prevent slide fastener from surprisingly pulling open, and its is simple in construction, convenient operation.
