A locking mechanism for a planning block comprises a locking part formed on the axle of a planing block, a locking plate which has a combined hole formed with a hole for locking the locking part to stop the rotation of the planing block and a hole for unlocking the locking part to allow the planing block to rotate, and a cover to move the locking plate in the direction to lock the planing block when opened and in the direction to unlock when closed, thereby enabling the planing block to be locked whenever the cover is opened.
