ABSTRACT:
A clutch device for a rollers' swinging mechanism of a belt sander, which includes a roller set, a swinging gear set, is composed of a control bar, a linking member and a clutch member. The roller set is driven by the swinging gear set to carry out an axial movement. The control bar is set with an eccentric wheel at its lower side, and the eccentric wheel is connected with the linking member, which is pivotally connected with the clutch member at its other end. When the eccentric wheel is driven to turn around, the linking member moves successively the clutch member to work for controlling the swinging gear set to provide two operating models optional for the belt sander.
