ABSTRACT:
A belt sander includes a main frame, a drive roller, a driven roller, a sand belt, and a sand belt replacement apparatus. Thus, the user only needs to rotate the control handle to move the driven roller relative to the drive roller so as to change the distance between the drive roller and the driven roller so that the user can adjust the tension of the sand belt easily and rapidly, thereby facilitating the user adjusting the tension of the sand belt, and thereby facilitating the user mounting and replacing the sand belt.
