Abstract

A dust coupler adapted to different dust outlet tubes has a collecting pipe connector and an elastic sheathing element. The collecting pipe connector has a first end and a second end being opposite to each other. The first end is configured to be inserted into a collecting pipe of a dust collection system for woodworking. The elastic sheathing element is connected to the second end of the collecting pipe connector, has a mouth, and is configured to be elastically sheathed onto a dust outlet tube of a woodworking machine. A woodworker first mounts the dust coupler on the collecting pipe, and the collecting pipe can be combined with any one of different dust outlet tubes of different woodworking machines having different sizes via the dust coupler. The dust coupler allows the collecting pipe to be quickly combined with or detached from the dust outlet tube.
