Abstract

This invention relates to structure of a connection seat and an improved structure of a suspension seat of a connection seat for a suspension round saw. The connection seat formed as one unit will not product error when the left-right angle of the sawing blade is adjusted and/or when the sawing blade moves up and down. The middle position of the suspension seat is provided with a plurality of securing sections so as the weight of the connection seat is distributed equally to the plurality of securing sections.
