A tool-shaft locking device for a planing machine is connected with a second end of the tool shaft having a first end connected with a belt wheel, including a bearing base, a locking rod, a spring and a locking button. The bearing base has a sidewise hole, two opposite deep position grooves at an upper and a lower side of the hole and two opposite shallow grooves at a right and a left side, and the locking rod has a first threaded end tightly engaging a center threaded hole of the locking button, which has two opposite position projections possible to be fitted tightly in the deep grooves so that the inner end of the locking rod may insert in one of position holes of the tool shaft body so as to lock the tool shaft immovable. Then a planing knife fixed on the tool shaft with bolts can be adjusted in its position, conveniently by easily screwing off the bolts.
