AI Technical Summary

Technical Problem

Existing electric screwdrivers require dragging the power transmission harness over a wide range of distances during use, resulting in poor operability, easy damage to the harness, and high labor intensity for workers.

Method used

A screw removal and installation device is designed, including a base fixing component and a multi-directional movable component. An electric screwdriver is connected to the multi-directional movable component, which is rotatably connected to the base fixing component and can extend and retract to achieve multi-angle and multi-directional movement of the electric screwdriver, avoiding dragging of the power transmission cable harness.

Benefits of technology

It improves the operability of electric screwdrivers, reduces the labor intensity of workers, extends the service life of power transmission harnesses, and avoids wear and tear on the harnesses.
