Embodiment Construction

[0013] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] Such as figure 1 Shown, a kind of screw comprises screw body 5, and described screw body 5 is cylindrical and its outer surface is provided with serrated thread, and the head surface of described screw body 5 is provided with cross-shaped groove; Said screw body There is an annular connector 1 on the edge of the head of 5, and four conical screws are welded on the connector 1. The surface of each screw consists of three parts, and the smooth surface 3 starts from the head near the screw body 5. , Thread surface 4 and blade surface 2. The surface of the screw body 5 is coated with a polymer material. The included angle of the four conical screws is 90 degrees.

[0015] 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...

Abstract

The invention provides a crew which comprises a screw body. The screw body is cylindrical, and the outer surface of the screw body is provided with a zigzag thread. A crossed groove is formed in the surface of a head of the screw body. An annular connecting piece is arranged at the edge of the head of the screw body. Four conical threaded rods are welded to the connecting piece. The surface of each threaded rod comprises a smooth face, a threaded face and a blade face sequentially from the portion close to the head of the screw body. The screw is simple in design and practical, connection of multiple objects can be achieved, and raw materials are saved.

Description

technical field [0001] The invention belongs to the technical field of hardware accessories, and in particular relates to a screw. Background technique [0002] Screws are the most widely used type of fastener. Fastener connection has become one of the indispensable connection methods in industry and life. As one of the fasteners, the screw connection is currently mostly used for single use and multiple connection methods. In this way, when it is necessary to connect several identical objects, such as atomic models, it is a waste of raw materials and easy to lose screws. Contents of the invention [0003] The problem to be solved by the present invention is to provide a self-tapping screw for connecting multiple objects at the same time. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0005] A screw, comprising a screw body, the screw body is cylindrical and its outer surface is p...
