Abstract
An elevation adjusting device of a belt-form saw machine is disclosed. An elevation adjusting unit has two elevation adjusting rods. A lower end of each elevation adjusting rod is installed with a screw rod. The machine table has two oil pressure rotary units. A universal linkage of a universal connector is connected between the two oil pressure rotary units. The oil pressure rotary units are screwed to the screw rods of the elevation adjusting rods so that the elevation adjusting rods of the screw rod will rise upward or descend so as to adjust the elevation of the saw teeth of the saw unit to a desired value. A universal linkage of a universal connector is connected between the two oil pressure rotary units so that the screw rods rise and descend synchronously, and thus the two elevation adjusting rods rise and descend synchronously.
