AI Technical Summary

Technical Problem

Existing screw fixing devices are difficult to securely fix under complex working conditions, and are prone to loosening, falling off, fatigue damage and corrosion. In addition, they lack flexibility and cannot adapt to the installation requirements of screws of different specifications.

Method used

The hydraulic telescopic rod drives the limiting mechanism to adjust the position. Combined with the locking mechanism and the limiting mechanism, the hollow threaded rod is locked by meshing with the elastic plate and the rotation limit of the movable connecting block to achieve a stable fixation of the screw, which can meet the installation requirements of screws of different specifications.

Benefits of technology

It improves the fixing stability and firmness of the screw under complex working conditions, reduces the risk of loosening, enhances the applicability to different specifications of screws and the flexibility of installation, and simplifies the operation steps.
