It is provided at least one anti-pulling screw on upper surface and around groove, which is made of the head of a nail and nail rod, described
The head of a nail be fixedly welded on the upper surface of screw cap, nose cone is processed into the upper end of the nail rod, and circular cone is located in nail rod
It is disposed with from top to bottom between head and the head of a nail towards the inclined ring tooth of the head of a nail.
Further, the planform of the groove is for quincunx or interior hexagon or with the quincunx of column.
Further, there are two anti-pulling screw settings, and two anti-pulling screws are oppositely arranged.
Further, the attachment screw is tapping screw.
3. beneficial effect
It is had the following beneficial effects: compared with existing well-known technique using technical solution provided by the utility model
(1) a kind of lines of the utility model install nail, simple in sturcture, ingenious in design, due to the upper surface of screw cap
Center position setting is fluted, therefore the head fits of auxiliary tool are inserted into groove, will connect spiral shell by auxiliary tool
Nail is screwed into wall, and due to being provided at least one anti-pulling screw on the upper surface of screw cap and around groove, can
Directly to tap payment to a porter by external force anti-pulling screw is entered inside payment to a porter, installation is simple firm in this way, and does not destroy foot
The decorative cover of line, does not affect the appearance；
(2) a kind of lines of the utility model install nail, and the head of a nail is fixedly welded on the upper surface of screw cap, anti-pulling
Stable connection between screw and attachment screw is formed with the anti-pitch thread of umbrella in nail rod, knocks in payment to a porter convenient for anti-pulling screw,
And payment to a porter is made to be not easy to be pulled out, so that installation is firm.

Specific embodiment
For the content for further appreciating that the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments.
Embodiment 1
In conjunction with Fig. 1, a kind of lines of the present embodiment install nail, including the attachment screw to be connected with wall, this implementation
Attachment screw is tapping screw in example, and attachment screw is made of screw cap 11 and screw rod 12, the upper surface centre bit of screw cap 11
Set place setting fluted 13,13 planform of groove had by existing market screwing any one, as long as not interfering
Later period anti-pulling screw is fixed and later period auxiliary tool is not interfered to turn work, the structure shape of the present embodiment further groove 13
Shape be it is quincunx (shown in Figure 2), will be even by auxiliary tool by the head fits insertion groove of auxiliary tool when use
Screw is connect to be screwed into wall, referring herein to auxiliary tool be electric screw driver, it is time saving and energy saving convenient for the installation of attachment screw,
And acted in groove 13 to be conducive to the cutter head of electric screw driver, the center position of groove 13 is provided with positioning column (ginseng
As shown in Figure 3), the cutter head of corresponding electric screw driver is equipped with the location hole to cooperate with positioning column；Screw cap 11 it is upper
Groove is provided at least one anti-pulling screw on surface, payment to a porter can be directly tapped by external force and make anti-pulling screw
Into inside payment to a porter, installation is simple firm in this way, and does not destroy the decorative cover of payment to a porter, does not affect the appearance, and anti-pulling screw by
The head of a nail 21 and nail rod 22 form, and the head of a nail 21 is fixedly welded on the upper surface of screw cap 11, anti-pulling screw and attachment screw it
