Abstract: A tenon and mortise are formed with a taper-dovetail shape. As the tenon is inserted into the mortise, because of the friction force between the contacting surfaces and the squeezing force of the taper, the tenon is fixed sturdily in the mortise and the tenon can be easily assembled or dismantled by a particular shaping of its outer surface.
