ABSTRACT:
A plane-blade adjusting device for a planing machine includes a blade shaft, a plurality of plane blades, plural covers and plural eccentric tubular posts. The blade shaft body is provided with plural set flat surfaces for each plane blade to rest on and then each cover secured on the plane blade and screwed tightly. The eccentric tubular post has an eccentric rotary portion formed in an upper portion, fitting in the rectangular hole of each plane knife and secured tightly on the shaft body for sandwiching a plane blade on the shaft body. So the eccentric tubular post is rotated to shift each plane blade up and down in a micro-distance with easiness, quickness and accuracy.
