ABSTRACT:
A working machine includes a main frame, a work table, a plurality of working tools, and a distance adjustment device. The distance adjustment device includes two guide tracks, two positioning members, and an adjustment unit. Thus, the adjustment unit can be used to adjust the position of the workpiece relative to the work table to adjust the working distance of the workpiece, thereby facilitating a user working the workpiece. In addition, the locking portion of each of the positioning rods is locked in the positioning holes of the respective positioning member closely, so that each of the fixing seats is fixed on the respective positioning member to position the adjustment unit so as to adjust the working distance of the workpiece exactly.
