Adjustable-angle wall surface polisher

The invention provides an adjustable-angle wall surface polisher which is driven by an external drive motor through a flexible shaft. Through an angle adjusting mechanism, a polishing head can move for angle adjustment in a relatively large range so as to polish a dead angle area. Dust collection holes of the wall surface polisher are uniformly distributed around a center hole of a dust collection cover and are concentric with a rotary shaft of a grinding disc so as to realize uniform dust collection. Moreover, a handheld main pipe of the wall surface polisher can be subjected to telescopic adjustment according to the need. The adjustable-angle wall surface polisher provided by the invention has a simple structure, is convenient to operate, reduces the labor intensity of an operator, and improves the polishing efficiency.
