Abstract
A locking device for a wooden planing machine is fixed on an upper surface of a machinery base combined movably with four posts located at four corners of a base of a wooden planing machine, including two brackets each located at two sides of the upper surface of the machinery base and having two sleeves separated with an opening on a bottom plate, a long drive shaft having two ends fixed with a cam located in the opening, and four tightening pins each passing through a coil spring placed in each of the sleeves and having its end fixed with a tightening member which is fixed with the end of each tightening pin and has a front concave surface to fit around the convex surface of the posts. Then a handle of the drive shaft is pressed down from an unlocked position to a locking position or vice versa, wherein the tightening pins are moved to tighten or loosen the tightening members against or from the posts to lock or unlock the machinery base.
