Abstract
A clutch device for a roller sand for controlling reciprocating movement of a roller includes a belt wheel, a connecting shaft and a adjusting button. The roller sander consists of a base, a motor set, a roller set and a linking device. The belt wheel is pivotally connected with the connecting shaft, mounted around by a belt that is also mounted around a belt wheel of a shaft of the motor set. In addition, the belt wheel of the clutch device is provided with plural fixing grooves at its front end. The adjusting button is connected with the connecting shaft, provided with a fixing bar fitting in a slot in an annular outer surface of said connecting shaft. Then the adjusting button is pushed in or pulled out to let the roller reciprocate or not. Therefore, two operating ways are optional for the roller sander.
