ABSTRACT:
A saw equipment includes a working table, a rotary arm unit, two adjustment members, a lock unit, a hacksaw, and a guide unit. The rotary arm unit has a rotary arm mounted pivotally on the working table, and two positioning plates respectively secured to two ends of the rotary arm. Each of the positioning plates has several angularly equidistant engaging slots formed therein. Each of the adjusting members includes a lock block and two parallel rods extending upward from the lock block. Each of the lock blocks has several angularly equidistant engaging tongues which engage a first set of the engaging slots of the corresponding positioning plate. The lock unit locks the adjusting members releasably on the rotary arm unit. The guide unit is vertically movable on the adjusting members so as to guide the saw blade to reciprocate on the adjusting members along a straight path. When the adjusting members are removed from the rotary arm unit, the engaging tongues can be engaged with a second set of the engaging slots so as to adjust the angle of the saw blade relative to a horizontal plane.
