Abstract
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.
Claims5
A locking mechanism for locking a planing block of a planing machine comprising a locking part formed on an axle of the planing block;
- a locking plate which has a combined hole including a hole for locking said locking part on said axle thereby preventing the rotation of the planing block and a hole for unlocking said locking part thereby allowing the planing block to rotate;
- a cover to press down said locking plate when it covers said planing block so that said hole for unlocking is engaged with said locking part and also to release the locking plate when it uncovers the planing block, an urging member for urging said locking plate so that said hole for locking is engaged with the locking part when said cover releases said locking plate, and a guiding unit along which said locking plate travels when the locking plate is moved in association with opening and closing of said cover.
