AI Technical Summary

Technical Problem

Existing putty scraper devices cannot accurately find the optimal fitting angle when facing irregular or rough walls, resulting in poor uniformity of the putty layer. Furthermore, the spring preset force may cause excessive pressure that damages the wall surface or affects the coating effect.

Method used

Design a putty scraper device, including a floating seat, a scraper assembly and a limiting device. The floating seat can float through an elastic device, and the limiting device can switch between working and non-working states, allowing the scraper to freely adjust its angle according to the wall condition, avoiding the limitation of the spring preset force.

Benefits of technology

It improves the uniformity and stability of the putty layer, avoids damage to the wall surface caused by excessive pressure, enhances the effect and safety of putty application, simplifies the structure and reduces power requirements.
