Problems solved by technology

[0002] Screws are widely used as a joint structure of parts. As a mechanism for fastening such screws, the following mechanisms have been generally used in the past: a plus-shaped "cross hole" is formed on the top of the screw, or a minus-shaped "one hole" is formed on the top of the screw. When these mechanisms are in use, they usually work with a screwdriver corresponding to the shape of the top. When some screwdrivers are not found, sometimes the staff directly tightens or loosens the screws by hand. However, at this stage The nuts of some screws on the market usually have a smooth surface, and it is more laborious to tighten the screws

Abstract

The invention provides a long screw, which comprises a screw rod (1) and a screw cap (2), wherein the screw cap (2) is provided with threads. According to the long screw provided by the invention, a friction force between the screw and hands can be increased through the threads arranged on the screw cap, thereby the screw is screwed with hands in a more convenient and labor-saving manner.

Description

technical field [0001] The invention relates to a long screw. Background technique [0002] Screws are widely used as a joint structure of parts. As a mechanism for fastening such screws, the following mechanisms have been generally used in the past: a plus-shaped "cross hole" is formed on the top of the screw, or a minus-shaped "one hole" is formed on the top of the screw. When these mechanisms are in use, they usually work with a screwdriver corresponding to the shape of the top. When some screwdrivers are not found, sometimes the staff directly tightens or loosens the screws by hand. However, at this stage The nuts of some screws on the market usually have a smooth surface, and it takes a lot of effort to tighten the screws. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a long screw that can be easily unscrewed. [0004] To achieve the above object, the present invention provides a long screw, includi...
