Benefits of technology

The purpose of the invention is to create a way to easily remove the central shaft of a sanding belt from a grinding machine. It does this using a special notch in the grinding machine and a locking post on the central shaft. This makes it simpler and faster to change the central shaft without having to remove the grinding machine.

Problems solved by technology

For example, as removing the central shaft of the sanding belt, a first hand tool is used to fix a connection column, and a second hand tool is applied to screw or unscrew the at least one screw bolt, thus replacing the connection column troublesomely.
