ABSTRACT:
A saw machine includes a base body with rear and front portions. A worktable extends from the rear portion toward the front portion, and has a sawing slot formed therethrough. An upright support arm has an intermediate section pivoted to the rear portion of the base body. An upper hollow arm extends above the front portion of the base body from an upper section of the support arm. A lower hollow arm extends below the front portion of the base body from a lower section of the support arm. A pair of upper and lower levers have rear ends pivoted respectively in the upper and lower hollow arms, and front ends aligned with each other to define cooperatively a straight line that passes through the sawing slot. An elongated saw blade has two ends connected to the front ends of the upper and lower levers so as to pass through the sawing slot. An angle-adjusting assembly is connected to the lower hollow arm for turning the lower and upper hollow arms and the upright support arm simultaneously to adjust an inclined position of the saw blade. A driving assembly is disposed adjacent and is connected to the front end of the lower lever to reciprocate the lower lever, thereby moving the saw blade along the straight line.
