Polishing tool

The invention discloses a polishing tool which comprises a bottom plate assembly, a polishing assembly and a polishing assembly. The bottom plate assembly comprises a bottom plate and a polishing piece fixed to the bottom plate. The machine shell assembly is arranged on the bottom plate and comprises a machine body machine shell; the driving mechanism is arranged to drive the bottom plate assembly to move; the supporting frame is arranged between the machine body shell and the bottom plate; the supporting frame comprises a floating arm, and when the floating arm is subjected to axial and/or radial acting force, the floating arm deforms to enable the machine shell assembly and the driving mechanism to move relative to the bottom plate; the diameter of the floating arm is larger than or equal to 1.0 mm and smaller than or equal to 4.0 mm. The supporting structure is high in supporting strength and meanwhile has high anti-seismic and anti-swing performance. 本发明公开了一种打磨工具，包括：底板组件，包括底板以及固定于所述底板上的打磨件；机壳组件，设于所述底板上，包括
