ABSTRACT:
A circular saw includes a work table, and an angle adjustment device mounted on the work table. The angle adjustment device includes an outer tube, a drive block, an inner rod, a drive gear, a fixed rod, a push barrel, and a driving unit. Thus, the user can rotate the handgrip of the outer tube at the front side of the work table to change and adjust the tilt or bevel angle of the pivot arm directly, thereby facilitating the user adjusting the tilt angle of the pivot arm. In addition, the user can rotate the handgrip of the outer tube easily and conveniently, so that the tilt angle of the pivot arm is adjusted exactly.
