A device for quick elevating and micro-adjusting a planing workbench includes a movable workbench pivotally assembled on a bottom base, an adjusting device pivotally connected with the bottom base by a connecting rod, an adjusting base provided with an elevating rod and a support shaft pivotally connected to a preset position of the movable workbench. When the elevating rod is activated to move up or down, the movable workbench will ascend or descend quickly by an interaction of the connecting rod. In case the elevating rod is rotated to activate the support shaft to turn around, the movable workbench is micro-adjusted to move up or down slightly. Then, a locking grip is provided at one end of the elevating rod for tightly locking the elevating rod, rendering it unmovable up or down any longer but merely capable to micro-adjust the movable workbench to ascend or descend slightly.
