A quick elevating and micro-adjusting device for the worktable of a manual planer includes a base, a stationary worktable, a movable worktable and an adjustment device. The adjustment device has its support shaft inserted in the fixing holes of two side plates of the movable worktable. The adjustment device has an elevating rod to be moved up or down for actuating the support shaft to quickly move the movable worktable upward or downward. A micro-adjusting rod has its worm engaged with the worm gear of a threaded shaft for rotating together to drive the threaded rod of the threaded shaft to rotate and move the holding frame of the threaded shaft, which is secured on the movable worktable. Thus, by turning the micro-adjusting rod, the movable worktable can be micro-adjusted in position. Thus the worktable can be adjusted quickly and precisely.
