A planing machine includes a carriage locking mechanism disposed above a cutter carriage, which in turn, is connected movably to upstanding posts of a machine base that is disposed below the cutter carriage. The locking mechanism includes a pair of post bracing members, each of which extends at one side of a respective pair of the posts, and has two post embracing units that embrace the respective pair of the posts. The post bracing members are mounted on the carriage. A right regulator plate is disposed above the carriage, and has a first end portion connected pivotally to the right post bracing member, and a second end portion formed with a wheel accommodating slot. A left regulator plate has a first end portion fixed to the left post bracing member, and a second end portion overlapping the second end portion of the right regulator plate. The second end portion of the left regulator plate defines a shaft mounting hole in communication with the wheel accommodating slot, and having an axis offset from an axis of the slot. A shaft unit is disposed rotatably through the shaft mounting hole in the left regulator plate, and has an eccentric wheel fixed thereto. The eccentric wheel is confined rotatably within the slot.
