A planing machine includes a carriage locking mechanism disposed above a cutter carriage, which in turn, is connected movably to left and right pairs of vertical posts. The carriage locking mechanism includes an elongated mounting plate disposed fixedly on the cutter carriage, a left locking unit having a pair of left clamping claws that press respectively and releaseably against the left pair of posts, and a right locking unit having a pair of right clamping claws that press releaseably against the right pair of posts. A cam member is disposed pivotally on the mounting plate. The cam member has two projections that engage respectively the left and right locking units. A pivot end of a rotary lever is mounted pivotally on the mounting plate, and is connected to the cam member so as to rotate synchronously with the cam member. The rotary lever is rotatable so as to remove the projections of the cam member from the left and right locking units. Left and right biasing units bias the left and right clamping claws to separate from the posts, respectively, when the projections of the cam member are removed from the left and right locking units.
