ABSTRACT:
A grinding machine with a length-adjustable dust collecting structure includes a dust collecting structure, and the dust collecting structure includes a dust collecting pipe and a moving element, and the moving element is installed at a front end of the dust collecting pipe for collecting dusts produced after a grinding process, and the moving element can be pushed or retracted from the front end of the dust collecting pipe, such that the displacement of the moving element at the front end of the dust collecting pipe allows the dust collecting pipe to effectively suck the dusts produced during the grinding process.
