Abstract
The invention discloses a crossed pan head self drilling screw which comprises a nut, a first screw rod, a second screw rod and a third screw rod, wherein the nut is fixedly connected to the upper end of the first screw rod, a crossed screwing hole is formed in the nut; the first screw rod, the second screw rod and the third screw rod are fixedly connected in sequence; an outer thread is formed on the second screw rod; and a drilling spiral notch is formed in the lower end of the third screw rod. By adopting the manner, the crossed pan head self drilling screw can drill for a connecting piece at the innermost end, and therefore, tightness between the connecting pieces is improved, fastening effect is good, and use effect is good.
Description
Technical field
The present invention relates to fastener areas, particularly relate to a kind of crossed pan head SELF DRILLING SCREWS.
Background technique
Crossed pan head SELF DRILLING SCREWS is used for fixing several link, and it needs on the link of innermost end, carry out boring and connects, and effectively can prevent innermost end screw from deforming or expanding like this, effectively ensure the tautness connected.
Summary of the invention
The technical problem that the present invention mainly solves is to provide that a kind of fastening effect is good, the better crossed pan head SELF DRILLING SCREWS of using effect.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of crossed pan head SELF DRILLING SCREWS, comprise: nut, the first screw rod, the second screw rod and the 3rd screw rod, described nut is fixedly connected on the upper end of described first screw rod, described nut is provided with cross Pan Kou, described first screw rod, the second screw rod, the 3rd screw rod are fixedly connected sequentially, and described second screw rod is provided with outside thread, and the lower end of described 3rd screw rod is provided with auger notch.
In a preferred embodiment of the present invention, described first screw rod is also provided with outside thread.
In a preferred embodiment of the present invention, the length of described first screw rod is greater than the length of described second screw rod.
In a preferred embodiment of the present invention, the length of described second screw rod is greater than the length of described 3rd screw rod.
The invention has the beneficial effects as follows: crossed pan head SELF DRILLING SCREWS of the present invention can be holed to innermost end link, improves the tautness between link, and fastening effect is good, and using effect is better.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of crossed pan head SELF DRILLING SCREWS one of the present invention preferred embodiment.
Embodiment
