Durable sander and oscillation buffer element applied to sander

Abstract

A durable sander comprises a body with a drive motor, a sanding disk driven by the drive motor to perform sanding movement against the body and at least one oscillation buffer element. The oscillation buffer element includes an upper connection bar fastened to the body, a lower connection bar fastened to the sanding disk and a plurality of buffer portions bridging the upper connection bar and lower connection bar in an integrated manner. Each buffer portion has a first connection end connected to the upper connection bar, a second connection end connected to the lower connection bar and an elastic buffer section interposed between the first connection end and second connection end. The length of the elastic buffer section is greater than the distance between the first connection end and the second connection end.
