Embodiment Construction

[0008] like figure 1 As shown, a screw includes a nail body 2 and a nail cap 1, concave and convex threads are evenly distributed on the nail body 2, the nail cap 1 is arc-shaped, and the upper end of the nail body 2 is broken out of the nail cap 1. The nail cap 1 not only increases the fixed action surface to improve the firmness of the fixation, but also prevents the speed of the nail body 2 from rusting to a certain extent, and has the characteristics of simplicity, practicality, convenience, reliability, and wide application range.

[0009] An embodiment of the present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention, and cannot be considered as limiting the implementation scope of the present invention. All equivalent changes and improvements made according to the application scope of the present invention shall still belong to the scope covered by the patent of the present invention.

Abstract

The invention discloses a screw which comprises a screw body and a screw head. Concave-convex threads are evenly distributed on the screw body. The screw head is arc-shaped. The tip of the upper end of the screw body is exposed out of the screw head. The screw has the advantages that the fixing acting face of the screw is increased by the screw head so as to increase fixing firmness, rusting speed of the screw body is reduced to a certain degree, and the screw is simple, practical, convenient, reliable, wide in application range, and the like.

Description

technical field [0001] The invention relates to a screw. Background technique [0002] Existing screws will rust in a short period of time, greatly reducing the utilization rate of the screws, and when fixing materials such as glass fiber reinforced plastics or asbestos tiles, the fixing reliability is poor, and safety accidents are likely to occur. Contents of the invention [0003] The purpose of the present invention is: to improve the fixation strength and prevent the rusting speed of the nail body, and to provide a screw with the characteristics of simplicity, practicability, convenience and reliability, and a wide application range. [0004] The technical solution of the present invention is: a screw, including a nail body and a nail cap, characterized in that concave-convex threads are evenly distributed on the nail body, the nail cap is arc-shaped, and the broken end of the nail body is exposed outside the nail cap. [0005] The advantages and positive effects of ...
