AI Technical Summary

Technical Problem

The existing double-ended screwdriver bits have fixed connections at both ends, which means that a large number of different sizes of screwdriver bits need to be carried in scenarios involving mixed screws of various sizes. Furthermore, the working head at one end cannot be replaced after it wears out, making it inconvenient to use.

Method used

A double-ended screwdriver bit with replaceable working heads was designed. By setting up a fixed frame, insertion slot, moving parts and compression spring, the working heads can be detachably connected and stably fixed. It supports the use of screws of different sizes, and the magnetic part provides attraction and wear-resistant layer to improve service life.

Benefits of technology

It achieves compatibility and stability of double-ended screwdriver bits on screws of different sizes, reduces misalignment and wear, and improves ease of use and durability.
