Patent attributes
A circular saw includes a worktable, a sliding unit including a mounting base mounted on the worktable and providing an accommodation slot and two sliding shafts axially slidably inserted through the mounting base at two opposite sides of the accommodation slot in a parallel manner, and a cutting unit including a saw arm pivotally connected between the two sliding shafts and providing an accommodation portion and a saw blade pivotally mounted at the saw arm. Thus, when the saw arm is in an upper limit position, the accommodation of the saw arm is partially disposed outside the accommodation slot. When the saw arm is in a lower limit position, the accommodation portion is received in the accommodation slot. Subject to the design described above, the circular saw achieves the effects of reduced overall dimension, low vibration and high cutting accuracy.
