When used for the connection and fixation of doors, windows, cabinets, etc. involving hinges, the traditional screw fastening method is usually used, and the screws are directly driven into the screw holes of the connected parts, and the screw end caps are directly exposed, which not only affects the connected parts. Moreover, the end caps of the screws exposed for a long time are easy to rust, and there are burrs in the end processing of the general screws. When used for fastening connections, the end caps of the screws are easy to scratch people, which affects the appearance and is not safe.

In pressure vessels such as oil cylinders, the existing sealing structures are all seals (such as O-rings, etc.) plus a retaining ring. The cross-sectional shape of the retaining ring is generally rectangular. The retaining ring of this shape is limited in the sealing structure. It protects the sealing ring and does not participate in the sealing effect.

In order to meet the needs of different assembled installation components, there are also hand-tightening methods for tightening the screws, but in actual use, ordinary manual screws can easily cause hand pain to the user, and the operation is extremely inconvenient; at the same time, due to tightening The contact area between the screw and the installation component is too small. If the user exerts too much force, the uneven force per unit area of the installation component will cause deformation and depression, which will affect the use. Therefore, a manual screw is proposed to solve the above problems.
