Abstract
A wood planing device includes a support carriage movably mounted on a wood planing machine, and a rotatable shaft rotatably mounted on the carriage and having a coupling segment. A coupling sleeve surrounds the shaft and is movable between engaging and disengaging positions to engage and disengage the shaft. A rolling member is driven to rotate by a rotational force from the coupling sleeve to feed-in a workpiece supported on the machine. A clutch member is disposed to connect the coupling sleeve and a reduction gear train when the coupling sleeve is in the disengaging position. As such, the rolling member can be rotated by a first rotational drive delivered by the shaft through the coupling sleeve at a high speed, or by a second rotational drive through the clutch member and the reduction gear train at a low speed.
