AI Technical Summary
In existing technologies, wall sanding devices cannot effectively perform electric sanding on inside corners such as wall corners and column bases, resulting in low sanding efficiency and requiring manual secondary sanding.
Design a wall putty sanding device that uses a Noller triangular grinding disc in conjunction with an eccentric shaft. The device is driven by a motor to cover the entire square groove, enabling electric sanding of internal corners such as wall corners and column bases. The eccentric shaft generates vibration to improve the sanding effect.
It enables electric sanding of inside corners such as wall corners and column bases, avoiding secondary manual sanding, improving sanding efficiency, and enhancing the sanding effect through vibration sanding.
