Screw capable of being screwed without tool and used for round pile production

Abstract

The invention discloses a screw capable of being screwed without a tool and used for round pile production. The screw comprises a screw body, a screw head, a screw tail, a mounting nut and a twisting handle, wherein the screw head is welded at the bottom of the screw body, the screw tail is arranged at the top of the screw body, a fixed annular block is welded at the bottom of the mounting nut, and the whole mounting nut is connected with the screw tail through threads. According to the screw, through the detachable structure of a bearing groove and a mounting block and the rotating effect of a fixing clamping block in a fixing clamping groove, the splicing operation between the twisting handle and the mounting nut can be rapidly achieved, the connecting component can achieve the connecting purpose without being screwed through the tool, the trouble of carrying the tool can be effectively avoided, and after use is completed, the whole twisting handle can be quickly disassembled, so that the whole assembly is flexible and free, mounting and the disassembly are quick and convenient, and meanwhile, the aesthetic property of the screw body after the whole installation is not influenced by the unfolded twisting handle.

Description

technical field [0001] The invention relates to the technical field of screws, in particular to screws for producing round piles without tools. Background technique [0002] Screw is a common fastener, which is widely used in machinery, electrical appliances and buildings. The general material is metal, which is cylindrical, and the surface is engraved with concave and convex grooves called threads. At present, during the installation and use of screws, generally need Some installation tools are used, because these installation tools are troublesome to carry, and it is impossible for customers to use installation tools such as wrenches to adjust the position on site. Therefore, in view of the above problems, it is proposed to solve the above problems by using screws that are tightened without tools for the production of round piles. above question. Contents of the invention [0003] The purpose of the present invention is to provide a screw that can be tightened without t...
