Abstract
A two-sided wood working planner includes a base, an adjustment seat and at least two auxiliary pressure cylinders. The base includes a plurality of straight screws thereon. The adjustment seat has a plurality of threaded holes corresponding to the screws. The screws are screwed to the threaded holes, so that the adjustment seat is mounted above the base. Two ends of each auxiliary pressure cylinder are connected to the base and the adjustment seat, respectively. The auxiliary pressure cylinder has a prestressing force to lift the adjustment seat with respect to the base. The flank at one side of threads of the screw is against the corresponding flank of threads of the threaded hole to eliminate the backlash between the threads so as to prevent the adjustment seat from vibrating during the operation of the two-sided wood working planner.
