fixing sections

232, 233 of the first deformation element 23 are used to connect the receiving unit 21 and the offset unit 22, and the

fixing sections

242, 243 of the second deformation element 24 are used to connect the offset unit 22 and the polishing pad 30, wherein the first deformation element 23 and the second deformation element 24 may be one of a spring, an elastic sheet or rubber.

In order to facilitate understanding of the deformation operation state of the present invention, in the embodiment, a spring is first used as the first deformation element 23 and the second deformation element 24, please refer to fig. 1 and fig. 2, in the initial state or when a user performs a polishing operation on a horizontal polishing surface, the receiving unit 21 and the polishing pad 30 are relatively horizontal, and the offset unit 22 and the receiving unit 21 can also be relatively horizontal.

Referring to fig. 3-1 and 3-2, which are schematic diagrams illustrating a deformation state of the polishing pad 30 on a non-horizontal polishing surface being a concave surface according to the present invention, when a user manually applies a force to the receiving unit 21 by the polishing power source 10 to polish the curved polishing surface, in order to make both sides of the polishing pad 30 generate a deformation state according to the curvature of the curved surface, at this time, the external force applied from the polishing power source 10 and the force fed back from both sides of the polishing pad 30 will cause the

central deformation sections

central deformation sections

231, 241 are different according to the material, including but not limited to one or a combination of compression or bending of the

central deformation sections

231, 241, and at this time, when the central deformation section 231 of the first deformation member 23 deforms, the

other fixing section
